RFID WIRELESS SCANNING SYSTEM FOR NON-RFID MOBILE DEVICES, AND RELATED OPERATING METHODS
First Claim
1. A wireless scanning system for obtaining data related to items, the system comprising:
- a radio frequency identification (RFID) reader configured to interrogate RFID tags and obtain tag data from interrogated RFID tags;
a mobile wireless device that is incapable of interrogating RFID tags; and
a device RFID tag in close proximity to the mobile wireless device, the device RFID tag being configured to convey data that identifies the mobile wireless device when interrogated by the RFID reader.

Abstract
A wireless scanning system for obtaining data related to items includes a radio frequency identification (RFID) reader configured to interrogate RFID tags and obtain tag data from interrogated RFID tags, and a mobile wireless device that is incapable of interrogating RFID tags. The system uses a device RFID tag in close proximity to the mobile wireless device, where the device RFID tag is configured to convey data that identifies the mobile wireless device when interrogated by the RFID reader. When the mobile wireless device is within close proximity to an item of interest having a corresponding item RFID tag, the RFID reader interrogates the device RFID tag and the item RFID tag. Thereafter, the RFID reader routes the item tag data in a manner destined for the mobile wireless device. This system enables the mobile wireless device to obtain the item tag data even though the mobile wireless device has no native RFID reader capabilities.

9. A wireless scanning method for obtaining data related to items, the method comprising:
-
generating a radio frequency identification (RFID) interrogation signal to interrogate RFID tags within an interrogation range; receiving, in response to the RFID interrogation signal, a first return signal from an item RFID tag corresponding to an item of interest, and a second return signal from a device RFID tag corresponding to a mobile wireless device; obtaining device tag data, which is conveyed in the second return signal; processing item tag data, which is conveyed in the first return signal, for routing to the mobile wireless device in accordance with the device tag data. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. In a wireless scanning system comprising a radio frequency identification (RFID) reader, an item of interest having an associated item RFID tag, and a mobile wireless device having an associated device RFID tag, the mobile wireless device being incapable of interrogating RFID tags, an RFID reader operating method comprising:
-
monitoring an item location of the item RFID tag, and a device location of the device RFID tag; detecting when a distance between the item location and the device location is less than a threshold distance; in response to the detecting step, interrogating the item RFID tag to obtain item tag data; and routing the item tag data in a manner destined for the mobile wireless device. - View Dependent Claims (18, 19, 20)
