The invention pertains to payment by means of user devices. The invention pertains more particularly to payment by means of a user device comprising means to make a payment through a digital wallet (also called an electronic wallet) which is at least partially associated with the user device. Such a user device can take the form of a mobile terminal.
Payment by mobile terminals is being promoted by numerous actors. This type of payment, designed to be more practical and more secured, takes mainly two forms. The first form uses a specific application of the terminal which contains bank data. This application uses contactless data transmission capacities to get physically connected to a merchant's payment terminal and carry out a payment transaction. This is an alternative to the insertion of a payment card into a payment terminal, with or without use of a pin code. The second form of payment by mobile terminal uses an identifier associated with the user's mobile terminal. This identifier is used by the possessor of the mobile terminal, in conjunction with a PIN code, to validate the transaction on the merchant's payment terminal (here again, this is an alternative to the insertion of a payment card into the merchant's terminal). These types of payment can replace the payment card for making purchases physically.
In addition to this type of use of the mobile terminal, there are uses of modes of payment using electronic wallets. These electronic wallets are often intended for payments of small sums of money to a merchant or again for making Internet payments. In this type of use, a payment service provider, to whom the user of the mobile terminal has entrusted bank data, takes charge of making payment of behalf of the user of the terminal. This payment services provider is often different from the bank establishment of which the user is a customer. To make payments by using this payment service provider, the user has a digital wallet which is installed in his terminal (or in a dedicated payment card). The merchant for his part, when he is an individual, has an application on his terminal associated with the payment services provider to enable validation of the payment. This type of payment using a payment services provider is also done without contact by means of what is called an NFC technology.
Payment services providers who propose electronic wallets each have a special architecture for data processing. The merchant's payment terminal (for example of an NFC type) therefore also needs to have a special application adapted to each payment services provider. Thus, to take two examples, the architecture of the “Google™Wallet” is not the same as the architecture of the “Paypal™ Wallet”.
Indeed, unlike in wallet architectures such as the Google™ or Isis™ architectures, where the credit/debit operations for cards, loyalty offers and information are loaded into and secured in the smartphone or in a micro SD card of the telephone, PayPal™ records its customers' data in a cloud.
The payment application for PayPal™ in the merchant's payment terminal is then completely different from the payment application for Google™ or Isis™. Since the development of payment solutions is done without consultation with the terminal manufacturers, the result is that the manufacturers have to adapt as best as they can to the different ways in which the payment service providers operate.
Concomitantly, there is an increasing number of offers coming from payment service providers. Payment terminal manufacturers, under pressure from the merchants, are therefore obliged to implement numerous special applications in their payment terminals to make sure that merchants can meet their clients' expectations, whatever their payment service provider.
Now, one of the problems encountered relates to the management of fleets of payment terminals. Indeed, when a payment service provider decides to modify the way in which the payment is managed through his digital wallet, the payment terminal manufacturer is then obliged to modify the application used for this provider in every terminal of the fleet. Another problem is the obligation to make sure that a transaction takes place within a given time span. Now, for example in the case of PayPal™, the numerous exchanges that occur in the network (the cloud) in order to carry out the transaction within a given time span make it necessary to have available high-performance communications networks, capable of transmitting and receiving information at high speed. This therefore increases the costs for the merchant of managing the digital wallets without any possibility for this merchant of passing on the cost to the customer. In other words, a part of the cost of processing this type of payment must be borne by the merchant.
There is therefore a need to propose a technique which, on the one hand, simplifies the task of management by manufacturers of terminals and managers of terminal fleets. On the other hand, proposed solution must limit the amount of network resources used to carry out payment operations.
The present technique at least partly resolves the above-mentioned problems. In particular, the present technique pertains to a method for processing a transaction within a server called an intermediate server.
The method comprises:
Thus, according to the proposed technique, it is not the payment terminal that processes the transaction and its progress. This task is performed by a server, which can be called an intermediate server or a proxy server, to which the payment terminal transmits a standardized request comprising at least some of the data needed to implement the transaction. It is therefore no longer necessary to have a plurality of applications available within the payment terminal, each application being adapted to a particular payment service provider. The optional character of the specific parameters varies according to the requirements of the transactional server.
According to one particular characteristic, said method furthermore comprises a step of decryption of the request for processing by means of a private key proper to said server.
Thus, it is ensured that the content of the request cannot be modified by a third-party entity. The request is first of all encrypted by the payment terminal and then transmitted to the intermediate server.
According to one particular embodiment, said step in which the server implements a payment transaction on the basis of data of said request for processing comprises:
Thus, the intermediate server acts towards the transactional server as if it were a payment terminal. For the transactional server, the transaction is done normally, without any modification of procedures.
According to one particular embodiment, said step of implementation, by the server, of a payment transaction on the basis of the data of said request for processing furthermore comprises:
Thus, it is possible, on the part of the payment terminal, to obtain complementary data which can be required to efficiently carry out the transaction from the server.
According to one particular characteristic, said at least one piece of complementary data belongs to the group comprising:
The present invention also relates to a server for processing payment transactional data coming from a digital wallet.
Thus, the technique described can be implemented by a server. Such a server for processing a transaction comprises:
The present technique also relates to a payment terminal capable of managing payments by using data given by a digital wallet.
The digital wallet can for example take the form of a smartphone which, depending on the architecture, comprises all or part of the data needed to implement the digital wallet. The smartphone can also be replaced by any other device used to fulfill the above-mentioned functions, and especially used to implement a digital wallet, such as a Smartwatch or a pair of Smartglasses, a contactless card (which in this case acts passively) or a 1D or 2D QR-code-based card.
In at least one embodiment, the technique also relates to a method for obtaining transactional data within a payment terminal.
This method comprises the following steps subsequently to a step for obtaining a transactional amount:
The proposed technique also relates to a device for obtaining transactional data installed within a payment terminal.
Such a device comprises:
According to a preferred embodiment, the different steps of the methods according to the invention described are implemented by one or more software programs or computer programs comprising software instructions to be executed by a data processor of a relay module according to the technique described and being designed to control the execution of the different steps by the methods.
The invention is therefore also aimed at providing a program that can be executed by a computer or by a data processor. This program comprises instructions to command the execution of the steps of a method as mentioned here above.
This program can use any programming language whatsoever and can be in the form of a source code, object code or a code that is intermediate between source code and object code, such as in a partially compiled form or in any other desirable form.
The technique described also aims to provide an information carrier readable by a data processor and comprising instructions of a program as mentioned here above.
The information carrier can be any entity or device whatsoever capable of storing the program. For example, the carrier can comprise a storage means such as a ROM, for example a CD ROM or a microelectronic circuit ROM or again a magnetic recording means, for example a floppy disk or a hard disk drive.
Again, the information carrier can be a transmissible carrier such as an electrical or optical signal which can be conveyed via an electrical or optical cable, by radio or by other means. The program according to the invention can be especially uploaded to an Internet type network.
As an alternative, the information carrier can be an integrated circuit into which the program is incorporated, the circuit being adapted to executing or to being used in the execution of the method in question.
According to one embodiment, the invention is implemented by means of software and/or hardware components. In this respect, the term “module” can correspond in this document equally well to a software component and to a hardware component or to a set of hardware and software components.
A software component corresponds to one or more computer programs, one or more sub-programs of a program or more generally to any element of a program or a piece of software capable of implementing a function or a set of functions as described here below for the module concerned. Such a software component is executed by a data processor of a physical entity (terminal, server, gateway, router, etc) and is capable of accessing hardware resources of this physical entity (memories, recording media, communications buses, input/output electronic boards, user interfaces, etc).
In the same way, a hardware component corresponds to any element of a hardware unit capable of implementing a function or a set of functions as described here below for the module concerned. It can be a programmable hardware component or a component with an integrated processor for the execution of software, for example an integrated circuit, a smartcard, a memory card, an electronic board for the execution of firmware, etc.
Each component of the system described here above naturally implements its own software modules.
The different embodiments mentioned here above can be combined with one another to implement the proposed technique.
Other features and advantages of the proposed technique shall appear more clearly from the following description of a preferred embodiment, given by way of a simple illustratory and non-exhaustive example and from the appended drawings, of which:
The general principle of the described technique, as explained here above, consists so to speak in removing the payment terminal from the payment sequence when implementing payment by means of a digital wallet, while at the same time preserving the benefits of the presence of this payment terminal (for example to obtain complementary data, to secure the transaction or quite simply to reassure the merchant and his customers). Indeed, for the merchant who ultimately is the individual most burdened by constraints on the use of electronic wallets (since he must accept every existing wallet), it is important that the payment terminal given to him by his bank should not to be the weak link in the payment sequence. The solution to this problem is to make sure that the payment terminal is not responsible for managing numerous applications for payment by means of a digital wallet. This also brings a definite advantage for the merchant who is not obliged to sign contracts with all the payment services providers. Besides, an intermediate server that replaces the payment terminal fulfils the role of a “meta-merchant” relative to the payment service providers thus simplifying the task of the merchant who no longer has any more than one contract to sign with the manager of the “meta merchant” to accept all types of digital wallets managed by this manager.
Thus, in at least one embodiment of the described technique, rather than having an application adapted to each digital wallet, the invention implements an application called a generic application within the payment terminal. This generic application is capable of obtaining and processing specific data. This generic application comprises means for obtaining at least two pieces of data: a digital wallet identifier (payment service provider's service identification code, which makes it possible to know which is the payment service provider to be contacted to process the transaction) and a user identifier (these two pieces of data are for example transmitted by the user device which may be a smartphone, a contactless card or QR code based card). It can be noted, in an alternative version that the digital wallet identifier can also be selected by the merchant on the payment terminal from a list of payment service providers available through the payment terminal (this list is for example transmitted periodically by an intermediate server).
The service identification code is proper to the payment services provider whose digital wallet is being used. This code is not standardized. Thus, the mobile terminal comprises means for searching for this code among the pieces of data transmitted by the payment application. The user's identifier for its part is not standardized either. However, it is transmitted during the initiation of the payment transaction.
According to the proposed technique, these two pieces of data are transmitted by the payment terminal to an intermediate server which is in a communications network and processes the transmitted data. The processing operations carried out by the intermediate server are chiefly the following: identifying the type of digital wallet used, building a request for processing on the basis of the type of digital wallet identified, this request for processing comprising the user's identifier. The user's identifier is formatted according to the requirements of a transactional server of the payment service provider. The request for processing is then transmitted to the transactional server by the intermediate server, using a dedicated application. Upon reception of the request for processing, the transactional server processes the transaction (i.e. it accepts or does not accept the payment for the user) jointly with the dedicated application of the intermediate user.
Thus, it is no longer the payment terminal that is in charge of managing the transaction with the payment service provider but an intermediate server (or proxy) that receives the data needed to process the transaction. Naturally, depending on the requirements of the transactional servers of the different payment service providers, the pieces of data transmitted are not the same. This means that the intermediate server can either request complementary data from the payment terminal (such as for example the amount of the transaction) or can request complementary information from the user device (when this device is able to do so). This complementary information travels through the payment terminal which then acts as a gateway between the user device and the intermediate server.
Here below we describe two special embodiments for implementing the present technique. It is clear however that these embodiments are not exhaustive but that they represent only one possibility of implementation adapted to an existing technical context. Thus, for example, when the user device is not a smartphone but for example a connected watch, the exchanges that take place between the payment terminal and the connected watch can be significantly different from those existing with a smartphone. What is important for the present technique is to obtain data making it possible to remove the payment terminal while the same time being transparent relative to the user device on the one hand and the transactional server of the payment service provider on the other hand.
In this embodiment, we describe a process for managing a transaction for purchasing one or more goods or services in the shop of a merchant which is an individual. This process uses a user terminal (TU) playing the role of the user device. This embodiment is described in relation with
Subsequently to this step of initialization:
From the viewpoint of the intermediate server, the technique that is the object of the present disclosure starts with:
Thus, as explained in this sequence of steps, the transaction is conducted from the intermediate server (SI). This server is, in a way, perceived by the transactional server (ST) as being the payment terminal (TP). In this embodiment, which presents a standard situation, the intermediate server (SI) can:
This choice can be considered to be a design choice. In reality, it responds to a specific problem: depending on the number of types of transactional servers to be addressed, the management of a general code used to address all types of transactional servers can be complicated. Besides, it can also be envisaged that the payment service providers will each provide their own applications (AppT)s. Thus, the solution that consists in loading and executing an application (AppT) adapted to the transactional server can be a more long-lasting solution.
Besides, depending on the needs of the transactional server (ST) for validating the transaction, additional pieces of data are provided either by the payment terminal (TP) (in this case, these pieces of data are integrated into the request (RqT) transmitted by the payment terminal (TP)), or provided directly by the intermediate server (SI). These pieces of complementary data include especially a localizing of the payment terminal (TP). Indeed, in order to make sure that the user's terminal (TU) is not used fraudulently, the transactional server (ST) may wish to make sure that the payment terminal (TP) and the user's terminal (TU) are situated in identical geographical zones. To this end, the transactional server (ST) can use the IP address of the payment terminal (TP) to obtain a localization (or another piece of data enabling a localization, such as a piece of GPS data or a piece of data for connection to a relay antenna of a GSM type). This means that at least one embodiment of the proposed technique uses a piece of data representing the IP address as a piece of data localizing the payment terminal (TP).
To make the transaction, the intermediate server (SI) emulates the behavior of the payment terminal (TP). Here below, we describe the different steps for implementing this transaction. This description is made with reference to
Thus, the intermediate server (SI) presents itself as the payment terminal (TP).
In a second embodiment, the transaction is managed in two stages. This embodiment is described with reference to
This embodiment has the advantage of not necessitating an excessively lengthy processing time and of being adapted to the environments in which the bit rates of data transmission by network (whether a wired network or a wireless network) are limited.
In a second stage, the intermediate server (SI) makes the transaction (steps 300 and 400) with the transactional server (ST) of the payment service provider. To this end, it uses the application (AppT) adapted to this service provider to make payment. The same data and the same messages are exchanged as in the case of the first embodiment. Thus the intermediate server (SI) retrieves the amount credited to the merchant.
Referring to
In at least one embodiment, the described technique can be implemented by means of a communications network to which the server is connected. In at least one embodiment, the described technique is implemented within a plurality of intermediate servers, for example distributed within a territory to be covered.
In at least one embodiment of the invention, the server is associated with a data base. This data base comprises, in addition to the information needed for identification and execution of transactions with transactional servers, data pertaining to merchants. Such data, stored in a secured manner in the data base, makes it possible for example on the basis of an identifier of the payment terminal to obtain the data needed to carry out the transaction on behalf of the merchant. These pieces of “merchant” data are for example the following: merchant's name, physical address, bank particulars, etc.
Referring to
These means are driven by the microprocessor by means of the program loaded into the memory of the terminal. Depending on the embodiments, the terminal also comprises other means for carrying out exchanges with the intermediate server and enabling the reception, from this server, of temporary encryption keys to carry out data exchanges in a confidential way.
Although the present disclosure has been described with reference to one or more examples, workers skilled in the art will recognize that changes may be made in form and detail without departing from the scope of the disclosure and/or the appended claims.
