Physical Point-of-Sale Integration With Third-Party Expense Systems

A computer-implemented method for point-of-sale (POS) third-party application integration implemented at a point of sale system that includes (i) a user interface;

• (ii) a transceiver configured to interrogate one or more tags:
• (iii) a memory storing a plurality of applications having respective identifiers, the applications being configured to interface with one or more application servers via respective one or more application programming interfaces (APIs);
• and (iv) a controller operatively connected to the user interface and the transceiver, wherein the method comprises:
• triggering, via the controller, the transceiver to interrogate the one or more tags to obtain a data string indicative of an application identifier and a user credential;
• identifying, via the controller, an application based on the application identifier:
• obtaining, via the controller, transaction information for a transaction performed by the user via the POS system:
• generating, via the controller, an instruction to submit the transaction information to an account associated with the user credential, wherein the instruction is formatted in accordance with the one or more APIs of the one or more application servers corresponding to the identified application;
• and
• transmitting, via the controller, the instruction to the one or more application servers.
