FIELD

The present application relates to the field of financial transaction security, and particularly to a card substitution prevention method and apparatus.

BACKGROUND

With the rapid development of social economy, transactions between merchants and customers are increasingly frequent. Self-service terminals (such as ATM, i.e., automatic teller machine) are greatly favored by customers due to advantages such as being convenient and efficient, 24 hours self service, wide distribution, and etc.

In a conventional self-service terminal, for example an ATM, an irregular-shaped mouth is mounted on a port of a card reader to protect a bank card, prevent the bank card from dropping and prevent the bank card from being taken away by criminals. However, there is also a potential safety hazard. While a customer is operating at an interface to perform a transaction after inserting a bank card into the card reader and entering a password, if a lawbreaker, at this time, inserts a false card into the irregular-shaped mouth of the card reader and then tells the customer that the customer's bank card has exited, and the customer, upon seeing the false card in the irregular-shaped mouth of the card reader, would consider that his own bank card has exited, and then takes out the false card in the irregular-shaped mouth of the card reader and leaves. Actually, the bank card of the customer is still in the card reader and the correct password has been entered; at this time, the lawbreaker may perform a transaction and withdraw cash from the bank account of the customer. This is how the lawbreaker stealthily substitutes a false card for the bank card of the customer and steals cash from the bank account of the customer at present by utilizing the feature of the conventional card reader that a card can be inserted into the irregular-shaped mouth of the card reader.

Therefore, in the field of self-service terminals such as ATMs, it is required to provide a method for protecting a card of a customer and effectively preventing the card of the customer from being stealthily substituted, thereby improving the service quality of a self-service terminal and maintaining the trade credit of a merchant.

DETAILED DESCRIPTION

A card substitution prevention method and apparatus for a self-service terminal are provided according to the present application, for effectively protecting a card of a customer and preventing the card of the customer from being stealthily substituted, thereby improving the service quality of the self-service terminal and maintaining the trade credit of a merchant.

For making the objects, features and advantages of the present application clearer and easier to be understood, the technical solutions according to the present application are described clearly and completely hereinafter in conjunction with the drawings in the embodiments of the present application. Apparently, the embodiments described hereinafter are only a part of the embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all of other embodiments, made by the person skilled in the art without any creative efforts, fall into the scope of the present application.

Referring to FIG. 1, an embodiment of a card substitution prevention method for a self-service terminal according to the present application includes steps 101 to 102.

Step 101 may include determining whether a card exists in a card reader of the self-service terminal; and performing step 102 if it is determined that a card exists in the card reader of the self-service terminal; and continuing to wait if it is determined that no card exists in the card reader of the self-service terminal.

Firstly, it may be determined whether a card exists in the card reader of the self-service terminal, and step 102 is performed if it is determined that a card exists in the card reader of the self-service terminal, and the self-service terminal continues to wait if it is determined that no card exists in the card reader of the self-service terminal.

Step 102 may include performing, by a card feeding portion of the self-service terminal, an alteration operation, to make the card feeding portion unable to receive another card and prevent the another card from being placed in the card feeding portion.

When it is known that a card exists in the card reader of the self-service terminal, it may be deemed that the self-service terminal is being used by a customer. Thus, the card feeding portion of the self-service terminal may perform an alteration operation, such that the card feeding portion cannot receive another card and the another card cannot be placed in the card feeding portion.

In this embodiment, in the case that a card exists in the card reader of the self-service terminal, the card feeding portion of the self-service terminal performs an alteration operation, such that the card feeding portion cannot receive another card and the another card cannot be placed in the card feeding portion. In this embodiment, after a card of a customer is inserted into the card reader, this card exists in the card reader of the self-service terminal, then the card feeding portion is altered to make a lawbreaker to unable to insert a false card into the card reader or place it in the card feeding portion, to prevent the card of the customer from being stealthily substituted by the false card of the lawbreaker, thereby effectively protecting the card of the customer and preventing the card of the customer from being stealthily substituted, and improving the service quality of the self-service terminal and maintaining the trade credit of a merchant.

For ease of understanding, the card substitution prevention method for the self-service terminal according to the embodiments of the present application is described in detail below. Referring to FIG. 2, another embodiment of the card substitution prevention method for the self-service terminal according to the present application includes steps 201 to 202.

Step 201 may include determining whether a card exists in a card reader of the self-service terminal; and performing step 202 if it is determined that a card exists in the card reader of the self-service terminal; and continuing to wait if it is determined that no card exists in the card reader of the self-service terminal.

Firstly, it may be determined whether a card exists in the card reader of the self-service terminal, and step 202 is performed if it is determined that a card exists in the card reader of the self-service terminal, and the self-service terminal continues to wait if it is determined that no card exists in the card reader of the self-service terminal.

Step 202 may include rotating a card feeding portion of the self-service terminal to cause an entrance of the card feeding portion to be misaligned with respect to a card feeding port of the card reader, to make the card feeding portion unable to receive another card and prevent the another card from being placed in the card feeding portion.

When it is known that a card exists in the card reader of the self-service terminal, it may be deemed that the self-service terminal is being used by a customer. Thus, the card feeding portion of the self-service terminal may be rotated to cause the entrance of the card feeding portion to be misaligned with respect to the card feeding port of the card reader, such that the card feeding portion cannot receive another card and the another card cannot be placed in the card feeding portion.

It may be understood that in the case that no card exists in the card reader, i.e., the self-service terminal is not being used, the entrance of the card feeding portion and the card feeding port of the card reader are aligned with respect to each other and thus a card may be inserted into the card reader through the entrance of the card feeding portion and the card feeding port of the card reader. After a card is inserted into the card reader, the entrance of the card feeding portion is misaligned with respect to the card feeding port of the card reader. Thus, other cards cannot pass through the entrance of the card feeding portion and the card feeding port of the card reader at the same time, and thus other cards cannot be inserted into the card reader. Meanwhile, the entrance of the card feeding portion may be closed after the card feeding portion is rotated to be misaligned with respect to the card feeding port of the card reader, thus another card cannot be inserted into the card feeding portion by a sufficient depth and the another card cannot be placed firmly in the card feeding portion.

It is to be noted that, the card feeding portion of the self-service terminal may be rotated upwards about a horizontal axis and may also be rotated downwards about the horizontal axis.

In this embodiment, in the case that a card exists in the card reader of the self-service terminal, the card feeding portion of the self-service terminal is rotated to cause the entrance of the card feeding portion to be misaligned with respect to the card feeding port of the card reader, such that the card feeding portion cannot receive another card and the another card cannot be placed in the card feeding portion. In this embodiment, after a card of a customer is inserted into the card reader, this card exists in the card reader of the self-service terminal, then the card feeding portion is rotated to make a lawbreaker to unable to insert a false card into the card reader or place it in the card feeding portion, to prevent the card of the customer from being stealthily substituted by the false card of the lawbreaker, thereby effectively protecting the card of the customer and preventing the card of the customer from being stealthily substituted, and improving the service quality of the self-service terminal and maintaining the trade credit of a merchant.

The solution in which the card feeding portion is altered by means of rotation has been mainly described hereinabove. A card substitution prevention method for the self-service terminal is described below in detail in which the card feeding portion is provided with a trigger switch to perform an alteration operation. Referring to FIG. 3, another embodiment of the card substitution prevention method for the self-service terminal according to the present application includes steps 301 to 304.

Step 301 may include determining whether a card exists in the card reader of the self-service terminal; and performing step 302 if it is determined that a card exists in the card reader of the self-service terminal; and performing step 303 if it is determined that no card exists in the card reader of the self-service terminal.

Firstly, it may be determined whether a card exists in the card reader of the self-service terminal. If it is determined that a card exists in the card reader of the self-service terminal, it may be deemed that the self-service terminal is being used, and step 302 may be performed at this time. If it is determined that no card exists in the card reader of the self-service terminal, it may be deemed that the self-service terminal is not being used, and step 303 may be performed.

Step 302 may include locking, by a trigger switch of a card feeding portion of the self-service terminal, a card feeding port of the card reader, to make the card feeding portion unable to receive another card and prevent the another card from being placed in the card feeding portion and/or the card feeding port.

When it is known that a card exists in the card reader of the self-service terminal, it may be deemed that the self-service terminal is being used by a customer. Thus, the trigger switch provided in the card feeding portion of the self-service terminal locks the card feeding port of the card reader, such that the card feeding portion cannot receive another card and the another card cannot be placed in the card feeding portion and/or the card feeding port.

It may be understood that, in the case that no card exists in the card reader, i.e., the self-service terminal is not being used, the trigger switch is switched on and the card feeding port of the card reader can receive a card. After a card is inserted into the card reader, the trigger switch locks the card feeding port of the card reader, thus other cards cannot be inserted into the card reader. The trigger switch may simply be a pin provided at the card feeding port of the card reader and may also be a baffle, and the trigger switch may have any structure as long as there is no sufficient space for a card to enter into the card feeding port after the trigger switch locks the card feeding port.

Step 303 may include unlocking, by the trigger switch, the card feeding port of the card reader.

When it is known that no card exists in the card reader of the self-service terminal, it may be deemed that the card in the self-service terminal has been retained by the self-service terminal. Then the trigger switch unlocks the card feeding port of the card reader and thus other cards can be inserted into the card reader.

Step 304 may include unlocking, by the trigger switch, the card feeding port of the card reader in the case that the card in the card reader is to be withdrawn, to allow the card to be withdrawn.

After a customer has inserted a card and has performed business transactions or business processes on the self-service terminal, the customer needs to withdraw the card, and the customer may perform a card withdrawing operation on the self-service terminal, then the trigger switch unlocks the card feeding port of the card reader when the card in the card reader is to be withdrawn, thus the card can be withdrawn.

The solution in which the card feeding portion is altered by means of a trigger switch has been mainly described hereinabove. A card substitution prevention method for the self-service terminal is described below in detail in which a card feeding port of a card reader may be opened or closed. Referring to FIG. 4, another embodiment of the card substitution prevention method for the self-service terminal according to the present application includes steps 401 to 404.

Step 401 may include determining whether a card exists in a card reader of the self-service terminal; and performing step 402 if it is determined that a card exists in the card reader of the self-service terminal; and performing step 403 if it is determined that no card exists in the card reader of the self-service terminal.

Firstly, it may be determined whether a card exists in the card reader of the self-service terminal. If it is determined that a card exists in the card reader of the self-service terminal, it may be deemed that the self-service terminal is being used, and step 402 may be performed at this time. If it is determined that no card exists in the card reader of the self-service terminal, it may be deemed that the self-service terminal is not being used, and step 403 may be performed.

Step 402 may include closing a card feeding port of the card reader by an operation of a card feeding portion of the self-service terminal, to make the card feeding portion unable to receive another card and prevent the another card from being placed in the card feeding portion and/or the card feeding port.

When it is known that a card exists in the card reader of the self-service terminal, it may be deemed that the self-service terminal is being used by a customer. Thus, the card feeding portion of the self-service terminal performs an operation to close the card feeding port of the card reader, thus the card feeding portion cannot receive another card and the another card cannot be placed in the card feeding portion and/or the card feeding port.

It may be understood that, in the case that no card exists in the card reader, i.e., the self-service terminal is not being used, the card feeding port of the card reader is opened and the card feeding port of the card reader can receive a card. After a card is inserted into the card reader, the card feeding portion performs an operation to close the card feeding port of the card reader, thus other cards cannot be inserted into the card reader. The closing of the card feeding port may be embodied as closing of a double door switch of the card feeding port of the card reader, or may also be achieved by blocking the card feeding port with a closed movable baffle, and the closing of the card feeding port may be realized in any manner as long as the card feeding port can be closed.

Step 403 may include opening the card feeding port of the card reader by an operation of the card feeding portion.

When it is known that no card exists in the card reader of the self-service terminal, it may be deemed that the card in the self-service terminal has been retained by the self-service terminal. Then the card feeding portion performs an operation to open the card feeding port of the card reader, thus other cards can be inserted into the card reader.

Step 404 may include opening the card feeding port of the card reader by an operation of the card feeding portion in the case that the card in the card reader is to be withdrawn, to allow the card to be withdrawn.

After a customer has inserted a card and has performed business transactions or business processes on the self-service terminal, the customer needs to withdraw the card, then the customer may perform a card withdrawing operation on the self-service terminal, and when the card in the card reader is to be withdrawn, the card feeding portion performs an operation to open the card feeding port of the card reader, thus the card can be withdrawn.

For ease of understanding, based on the embodiment described in FIG. 4, the card substitution prevention method for the self-service terminal according to the embodiments of the present application is described below in a practical application scenario.

A: a card feeding port of a card reader of a self-service terminal is in an open state and an entrance of a card feeding portion is also in an open state.

B: a customer uses the self-service terminal, inserts a card into the card feeding port of the card reader via the entrance of the card feeding portion, and the card enters into the card reader.

C: after the card has existed in the card reader, a double door switch of the card feeding port of the card reader is closed, i.e., the card feeding port of the card reader is closed, and at this time, if a lawbreaker intends to cheat the customer with a false card, the lawbreaker would find that the false card cannot be inserted into the card feeding port and also cannot be placed at the position of the card feeding port, and if being forcibly placed at the position of the card feeding portion, the false card would drop, therefore, the lawbreaker cannot stealthily substitute the card of the customer with the false card.

D: after the customer used the self-service terminal and needs to withdraw the card, a card withdrawing operation is performed on the self-service terminal, the double door switch of the card feeding port of the card reader is opened and the card is withdrawn, thus the customer completes the transaction safely.

E: if the card is retained by the self-service terminal after the customer inserts the card into the card reader, at this time the self-service terminal would give a card retaining prompt and the double door switch of the card feeding port of the card reader is opened again to wait to be used by a next customer.
