Methods and systems for verification of operations of computer terminals and processing networks

A computer-implemented method for verifying operation of a payment terminal and a payment processing network linking the payment terminal to a payment processor, the method implemented by at least one verification computing module including at least one processor in communication with a database, said method comprising:

• receiving, via the payment processing network, a test request message from the payment terminal, the test request message initiated by a user and corresponding to a test payment card transaction, the test request message including at least a test account number and a void flag;
• identifying the void flag included in the test request message;
• bypassing a settlement process for the test payment card transaction based on the identified void flag;
• determining an operating status of the payment terminal and the payment processing network by analyzing at least one of i) a connectivity between the payment terminal and the payment processor, ii) a transmission time of the test request message, and iii) a data integrity of the test request message;
• generating a test response message based upon the determination, the test response message including an indication of the status of the payment processing network and the payment terminal;
• and
• transmitting the test response message, via the payment processing network, to the payment terminal for notifying the user.

A non-transitory computer-readable storage medium having computer-executable instructions embodied thereon, wherein when executed by at least one verification computing module including at least one processor in communication with a database, the computer-executable instructions cause the verification computing module to:

• receive, via a payment processing network linking a payment terminal to a payment processor, a test request message from the payment terminal, the test request message initiated by a user and corresponding to a test payment card transaction, the test request message including at least a test account number and a void flag;
• identify the void flag included in the test request message;
• bypass a settlement process for the test payment card transaction based on the identified void flag;
• determine an operating status of the payment terminal and the payment processing network by analyzing at least one of i) a connectivity between the payment terminal and the payment processor, ii) a transmission time of the test request message, and iii) a data integrity of the test request message;
• generate a test response message based upon the determination, the test response message including an indication of the status of the payment processing network and the payment terminal;
• and
• transmit the test response message, via the payment processing network, to the payment terminal for notifying the user.
