Multiplexing-based validation via a proxy card at a terminal device

A method, comprising:

• identifying, by one or more processors coupled with memory, from one or more slots corresponding to one or more integrated circuit cards, a slot corresponding to an integrated circuit card of the one or more integrated circuit cards;
• validating, by the one or more processors, the slot using a proxy card in communication with one or more devices;
• determining, by the one or more processors via a circuit of the proxy card, that the integrated circuit card is coupled with the one or more devices;
• initiating, by the one or more processors, via an automation script, a synthetic transaction to be executed using data of the integrated circuit card;
• executing, by the one or more processors responsive to the determination and via the one or more devices, the synthetic transaction in accordance with the automation script using the data of the integrated circuit card;
• and
• determining, by the one or more processors responsive to the execution of the synthetic transaction, a validation status of the integrated circuit card.

A non-transitory computer readable medium storing processor-executable instructions which, when executed by one or more processors, cause the one or more processors to:

• identify, from one or more slots corresponding to one or more integrated circuit cards, a slot corresponding to an integrated circuit card of the one or more integrated circuit cards;
• validate the slot using a proxy card in communication with a terminal device of the one or more devices;
• determine, via a circuit of the proxy card, that the integrated circuit card is in communication with the terminal device;
• initiate, via an automation script, a synthetic transaction to be executed using data of the integrated circuit card;
• execute, responsive to the determination and via a point of sale device of the one or more devices, the synthetic transaction in accordance with the automation script using the data of the integrated circuit card;
• and
• determine, responsive to the execution of the synthetic transaction, a validation status of the integrated circuit card.
