Method and system for facilitating secure card-based transactions

A method for facilitating secure card-based transactions, the method comprising:

• receiving, by an electronic chip of a transaction card, upon activation, a transactional input provided by a cardholder of the transaction card for initiating a transaction, wherein at least one input button on the transaction card is used for providing the transactional input;
• generating, by the electronic chip, an electrical signal based on the transactional input, wherein the electrical signal includes encrypted transactional data associated with the transaction card;
• converting, by a signal transmitter of the transaction card, the electrical signal to one or more light pulses;
• and
• transmitting, by the signal transmitter, the one or more light pulses to one of a user device of the cardholder or a terminal device for executing the transaction, wherein the transaction is processed by an issuer of the transaction card based on the encrypted transactional data included in the one or more light pulses.

A system for facilitating secure card-based transactions, the system comprising:

• a transaction card, comprising:
• at least one input button for receiving a transactional input provided by a cardholder of the transaction card for initiating a transaction;
• an electronic chip that is coupled to the input button and configured to generate, upon activation, a first electrical signal based on the transactional input, wherein the first electrical signal includes encrypted transactional data associated with the transaction card;
• and
• a signal transmitter that is coupled to the electronic chip and configured to:
• receive the first electrical signal from the electronic chip, and
• convert the first electrical signal to one or more light pulses;
• and
• a terminal device configured to:
• receive the one or more light pulses from the transaction card,
• convert the one or more light pulses to a second electrical signal that includes the encrypted transactional data required for processing the transaction, wherein the transaction is processed based on the encrypted transactional data.
