Personal item reminder
First Claim
1. A system for detecting the presence of items labeled with radio frequency (RFID) tags, comprising:
- a memory for storing a current list of at least one item;
an RFID interrogator for sending signals to bigger RFID tags;
an RFID receiver for receiving and identifying signals transmitted by RFID tags; and
a tracker for receiving a query from a user through a user interface, for instructing the RFID interrogator which of at least one RFID is to be searched for, for receiving from the RFID receiver an identification of any items in the current list for which the RFID tag is not within detection range, and for displaying on the user interface an identification of any items for which the RFID tag is not within detection range; and
a location detector for determining a current location of the personal communication device.

Abstract
A system and method are provided for allowing users to verify the presence of personal items. RFID tags are attached to personal items, and the items are entered into a list. The user makes travel lists from the list of items. When traveling, the user queries the system to determine whether all personal items in the travel list are within range of the system. The system checks for the presence of the RFID tags associated with the items in the travel list. If any RFIDs are not present, the user is alerted. Optionally, the system updates the last known location of items whenever checking for the presence of personal items, so that if an item is not found the user can determine where the item was last known to have been.

8. A method of detecting the presence of items labeled with radio frequency identification (RFID) tags, comprising:
-
storing a current list of at list one item; in response to a query by a user, detecting whether the RFID tag of each item in the current list is within detection range; and for each item whose RFID tag is not within detection range, notifying the user that the item is missing, wherein storing the current list comprises storing the current list in a central database operated by a network provider. - View Dependent Claims (9, 10, 11, 12, 13, 14)
