Abstract: Techniques described herein are directed to point-of-sale (POS) authorization and access control. A POS application operating in a first state can send a first instruction to a reader device to prepare to read payment data associated with a payment instrument and, responsive to receiving the payment data from the reader device, can process a transaction using the payment data. In a second state, the POS application can send a second instruction to the reader device to prepare to read non-payment data associated with an identification instrument of a user and, responsive to receiving the non-payment data from the reader device, can verify an identity of the user and/or grant the user permission to perform an operation. The POS application can transition between the first state and the second state based at least in part on a type of instrument to be read by the reader device.

Abstract: The ownership verification and reassignment tracking solution of the present disclosure can be used to identify if a telephone number belongs to a stated customer of a business and identify any change in the telephone status on a periodic basis to ensure continued ownership of the telephone number with the stated customer. Real-time telephone number ownership and disconnection and port history can be used. This data can be accessed directly from the telephony carriers. Ownership and porting data from publicly available data sources can also be used, in some embodiments, to provide complex and comprehensive ownership verification and ownership reassignment tracking for a telephone number.
