Patent attributes
A system includes a service provider device and a point of sale (POS) device. A session between a user device and the POS device is established. An authentication request associated with the user device is provided via a user interface of the POS device. Subsequent to an authentication of information, responsive to the authentication request, the POS device receives funding instrument (FI) proxy information corresponding to FIs, which is unusable to identify the FIs by a merchant. A selectable representation corresponding to the FI proxy information is provided via the user interface. Responsive to receiving an indication of a selected member from the selectable representation, information for the selected member is sent. The service provider device determines that the session corresponds to an account associated with the user device and the merchant, and performs a transaction for the session using a first FI that corresponds to the selected member.
