Tap on mobile device zones

A mobile device for performing a transaction with a payment card, the mobile device comprising:

• a first Near Field Communication (NFC) device;
• a memory;
• a processor coupled to the first NFC device and the memory, wherein the processor is configured to:
• perform a calibration process that discovers a location within the first mobile device where the first NFC device is located based on exchanging information between the first NFC device and a third NFC device during the calibration process, and the processor performing the calibration process further comprises the processor to:
• display a visual indication of a potential tap zone corresponding to a potential location where the first NFC device may be located,
• determine whether information has been read by the first NFC device from the third NFC device as a result of a tap of the third NFC device at the potential tap zone, and
• when information is determined not to have been read by the first NFC device,
• determine that another potential tap zone exists in a different location where the first NFC device may be located in the first mobile device,
• display another visual indication corresponding to the different location where the another potential tap zone is located, and
• repeat the determining that another potential tap zone exists and the displaying the another visual indication until information is determined to have been read by the first NFC device from the third NFC device, and
• when information is read by the first NFC device at either the potential location or the different location, store the potential location or the different location where the information has been read as a location within the first mobile device where the first NFC device is located,
• create, based on the location of the first NFC device, a user interface depicting an image of a tap zone, the user interface different from a user interface rendered on the first device, and the tap zone being an area of the first mobile device that a second NFC device of a second mobile device may be placed in proximity to enable NFC communication to occur between the first and second NFC devices, and
• send the user interface to the second mobile device that contains the second NFC device to cause the second mobile device to display the user interface with the image on a display screen of the second mobile device.

A non-transitory computer readable storage medium, having instructions stored thereon, which when executed by a processing system of a first mobile device, cause the first mobile device to perform operations, comprising:

• performing a calibration process that discovers a location within the first mobile device where a first Near Field Communication (NFC) device is located based on exchanging information between the first NFC device and a third NFC device during the calibration process, and performing the calibration process further comprises:
• displaying a visual indication of a potential tap zone corresponding to a potential location where the first NFC device may be located,
• determining whether information has been read by the first NFC device from the third NFC device as a result of a tap of the third NFC device at the potential tap zone, and
• when information is determined not to have been read by the first NFC device,
• determining that another potential tap zone exists in a different location where the first NFC device may be located in the first mobile device,
• displaying another visual indication corresponding to the different location where the another potential tap zone is located, and
• repeating the determining that another potential tap zone exists and the displaying the another visual indication until information is determined to have been read by the first NFC device from the third NFC device, and
• when information is read by the first NFC device at either the potential location or the different location, storing the potential location or the different location where the information has been read as a location within the first mobile device where the first NFC device is located;
• creating, based on the location of the first NFC device, a user interface depicting an image of a tap zone, the user interface different from a user interface rendered on the first device, and the tap zone being an area of the first mobile device that a second NFC device of a second mobile device may be placed in proximity to enable NFC communication to occur between the first and second NFC devices;
• and
• sending the user interface to the second mobile device that contains the second NFC device causing the second mobile device to display the user interface with the image on a display screen of the second mobile device.
