1. A computer-readable memory device having instructions stored thereon that, in response to execution by a mobile device, cause the mobile device to perform operations comprising:
- querying a purchase transaction device to request a radio frequency identification (RFID) number associated with a purchase item;
comparing the RFID number with a library of items associated with a plurality of RFID numbers to identify a description of the purchase item;
combining the RFID number together with the description to form a composite file;
querying the purchase transaction device with at least a portion of the composite file to determine an availability of the purchase item; and
transmitting the composite file from the mobile device to the purchase transaction device to request the purchase item.

14. An apparatus comprising:
-
means for querying a purchase transaction device to request a radio frequency identification (RFID) number associated with a purchase item; means for comparing the RFID number against a library of items available for purchase to identify a description of the purchase item, wherein the library of items comprises descriptions of the items, and wherein each of the items is associated with a unique RFID number; means for combining the RFID number together with the description to form a composite file, wherein the purchase transaction device is further queried with at least a portion of the composite file to determine an availability of the purchase item; and means for transmitting the composite file from a mobile device to the purchase transaction device to request the purchase item. - View Dependent Claims (15, 16, 17, 18, 19, 20)
