Systems and methods for wireless purchase transactions

A non-transitory computer readable medium containing instructions that when executed by at least one processor cause the at least one processor to perform wireless transactions operations comprising:

• accessing a data structure containing identities of a plurality of display areas and identities of a plurality of products located in the plurality of display areas;
• receiving from a mobile communications device a request for information related to a particular display area, wherein the mobile communications device is located in front of the particular display area and at least one receiver is located in the particular display area;
• receiving location information associated with a locus of the mobile communications device, wherein the at least one receiver is configured to receive wireless signals directly from the mobile communications device;
• in response to the location information, performing a look up in the data structure to identify the particular display area;
• determining, based on the signals received via the at least one receiver, a location of the mobile communications device in relation to the particular display area, wherein determining the location includes using a phase, amplitude, frequency, variation, or data content of the signals received via the at least one receiver;
• based on the identification of the display area, retrieving from the data structure product-related information associated with products located in the particular display area;
• and
• transmitting the product-related information to the mobile communications device;
• and
• prioritizing the transmitted product-related information based on the proximity of the plurality of products to the mobile communications device.
