Abstract

The present disclosure is related to a field of payment transactions using a card that discloses a computer-implemented method and a system for restricting a transaction while using a payment card. A card processing server may receive card details, a transaction amount, a flag, and signature data of the payment card from a remote terminal upon initiating a transaction using the payment card. Further, the card processing server validates the payment card based on the card details and the signature data of the payment card and thereafter determines a value associated with the flag upon successful validation. The value associated with the flag indicates one of two conditions, e.g., a true condition and a false condition. Based on the condition indicated by the flag, the card processing server performs one of a first action and a second action related to either processing or declining the transaction.

First claim

What is claimed is:

1. A computer-implemented method comprising:
receiving, by a card processing server, card details, a transaction amount, a flag, and signature data of a payment card from a remote terminal communicatively interfaced with the payment card for initiating a transaction;
validating, by the card processing server, the payment card based on the card details and the signature data of the payment card;
determining, by the card processing server, a value associated with the flag received from the remote terminal upon successful validation, wherein the value associated with the flag indicates one of two conditions;
performing, by the card processing server, one of a first action and a second action based on the condition indicated by the flag, wherein the first action comprises: processing the transaction when the transaction amount is determined to be less than a predefined transaction limit; and declining the transaction when the transaction amount is determined to be more than the predefined transaction limit, wherein the second action comprises processing the transaction; and
determining, by the card processing server, an attachment or a detachment of a first portion of the payment card and a second portion of the payment card based on the value associated with the flag received from the remote terminal, wherein the first portion of the payment card is configured with a primary chip and the second portion of the payment card is configured with a secondary chip.

2. The computer-implemented method of claim 1 , wherein the signature data comprises at least one of a first signature associated with the primary chip of the payment card and a second signature associated with the secondary chip of the payment card.

3. The computer-implemented method of claim 1 , wherein validating the payment card comprises relating a first signature associated with the primary chip of the payment card and a second signature associated with the secondary chip of the payment card to detect a match.

4. The computer-implemented method of claim 1 , wherein the attachment is determined when the value associated with the flag indicates a true condition, wherein the value is set to indicate the true condition when signature data received at the remote terminal comprises a first signature associated with the primary chip and a second signature associated with the secondary chip.

5. The computer-implemented method of claim 1 , wherein the detachment is determined when the value associated with the flag indicates a false condition, wherein the value is set to indicate the false condition when signature data received at the remote terminal comprises one of a first signature associated with the primary chip or a second signature associated with the secondary chip.

6. A card processing server comprising:
at least one processor; and
a memory communicatively coupled to the processor, wherein the memory stores processor-executable instructions, which, on execution, causes the at least one processor to:
receive card details, a transaction amount, a flag, and signature data of a payment card from a remote terminal communicatively interfaced with a payment card for initiating a transaction;
validate the payment card based on the card details and the signature data of the payment card;
determine a value associated with the flag received from the remote terminal upon successful validation, wherein the value associated with the flag indicates one of two conditions;
perform one of a first action and a second action based on the condition indicated by the flag, wherein the first action comprises: processing the transaction when the transaction amount is determined to be less than a predefined transaction limit; and declining the transaction when the transaction amount is determined to be more than the predefined transaction limit, wherein the second action comprises processing the transaction; and
detect an attachment or a detachment of a first portion of the payment card and a second portion of the payment card based on the value associated with the flag received from the remote terminal, wherein the first portion of the payment card is configured with a primary chip and the second portion of the payment card is configured with a secondary chip.

7. The card processing server of claim 6 , wherein the signature data comprises at least one of a first signature associated with the primary chip of the payment card and a second signature associated with the secondary chip of the payment card.

8. The card processing server of claim 6 , wherein the processor validates the payment card by relating a first signature associated with the primary chip of the payment card and a second signature associated with the secondary chip of the payment card to detect a match.

9. The card processing server of claim 6 , wherein the processor determines the attachment when the value associated with the flag indicates a true condition, wherein the value is set to indicate the true condition when the signature data received at the remote terminal comprises a first signature associated with the primary chip and a second signature associated with the secondary chip.

10. The card processing server of claim 6 , wherein the processor determines the detachment when the value associated with the flag indicates a false condition, wherein the value is set to indicate the false condition when the signature data received at the remote terminal comprises one of a first signature associated with the primary chip or a second signature associated with the secondary chip.

11. A payment card comprising:
a first portion with a primary chip;
a second portion with a secondary chip;
a mechanism capable of detachably connecting the first portion and the second portion; and
a physical communication link configured between the primary chip and the secondary chip to communicatively connect the first portion and the second portion of the payment card, wherein the physical communication link facilitates a determination whether the first portion is physically intact with the second portion, wherein the primary chip is associated with a first signature and the secondary chip is associated with a second signature, and wherein the first signature and the second signature facilitate authentication of the first portion and the second portion of the payment card when the first portion and the second portion are physically intact.

12. The payment card of claim 11 , wherein the physical communication link is further configured to transmit signature data from the primary chip and the secondary chip to a remote terminal when the payment card is interfaced with the remote terminal, wherein the signature data comprises at least one of the first signature and the second signature.

13. The payment card of claim 11 , wherein the mechanism is a magnetic link.

14. A system comprising:
a payment card;
a remote terminal; and
a card processing server,
wherein the remote terminal is configured to:
retrieve card details from the payment card communicatively interfaced with the remote terminal;
receive signature data from at least one of a primary chip of the payment card and a secondary chip of the payment card;
set a value of a flag to indicate a true condition, when the signature data is received from the primary chip and the secondary chip, or a value of the flag to indicate a false condition, when the signature data is received from one of the primary chip or the secondary chip;
transmit the card details, the signature data, the flag, and a transaction amount to the card processing server associated with the remote terminal fo
