2. Description of the Related Art
Currently, there are hundreds of magnetic stripe readers/swipers on the market. All of them are at least as long as the credit card itself. There are different types of card readers/swipers exist in the market. One of the types is a traditional card swiper with a single rail, which allows a card to be held against a base of the reader by a user and moved across a read head of the reader. Another type of a card reader guides a card by a two sets of rails and a backstop. When the user has inserted the card against the backstop, the card is read as it is removed from the swiper. The magnetic stripe cards having the standard specifications can typically be read by the point-of-sale devices at a merchant location. When the card is swiped through an electronic card reader at a checkout counter in a merchant store, the reader usually uses a built-in modem to dial a number of a company that handles the credit authentication requests. After an account is verified, an approval signal is sent back to the merchant to complete a transaction.
The conventional swipe device using the magnetic card readers for an electronic payment is bulky. Further the merchant has to produce the printed receipts for the customer, which is very cumbersome for the merchant handling the multiple customers. Also the merchant has to keep a record of all the printed receipts, to avoid a dispute about the transactions. It is advantageous for an individual to make a payment to another individual or merchant by swiping his magnetic stripe card through a reader connected to a mobile device. The mobile device should include a communication medium such as GPRS, WiFi, Bluetooth, etc., to transmit the card data to the server. Further the mobile device should be carried everywhere.
At present, there were huge developments in providing the card reader for a mobile device. In the currently available systems, a portable swipe machine is provided for mobile devices and the card data is encrypted on the mobile device. Hence there is a chance of an insecure transaction over the mobile device. Further the existing systems communicate the relevant data through the electrical signals, which are extremely slow compared to the electromagnetic signals. In the current scenario, the communication is always performed on an IP network, since the IP networks are wide spread. Further the existing devices work only with the high end devices such as iPhone, iPad or any other smart phone, thereby making the system very costly for the prospective users. Further the swipe machines used presently are active devices, where the machines need to be charged with an external power supply or through a connected device.
In view of the above facts, there is a need for a secure electronic transaction. There is also a need for a system and method for providing a secure electronic transaction in a cost effective manner. Further there is a need for a system and method to enable a fast, efficient and secure electronic transaction by using a dongle device. Yet there is a need for a system and method to utilize the fast and efficient IP communication, thereby reducing the need for the use of electrical signal.
The above mentioned shortcomings, disadvantages and problems are addressed herein and which will be understood by reading and studying the following specification.
The primary object of the embodiments herein is to provide a dongle device for a secure electronic transaction.
Another object of the embodiments herein is to provide a dongle device with tamper proof characteristics for a secure electronic transaction.
