Abstract
RFID-based systems and methods are presented. A portable electronic device according to one embodiment of the present invention includes an electrical system, a controller coupled to the electrical system, a display screen coupled to the electrical system, input devices coupled to the electrical system, and an RFID tag coupled to the electrical system such that removal or disablement of the tag causes disablement of at least some functionality of the device. A Radio Frequency Identification (RFID) system according to an embodimient of the present invention includes an RFID device tag coupled to a device and an RFID user tag associated with a user. The device tag is associated with the user tag. At least some functionality of the device is disabled based on whether or not a presence of the user tag is detected within a vicinity of the device tag.

57. A method for selectively enabling and disabling a device, the method comprising:
-
receiving an authorization code from an interrogator, the authorization code indidcating that a valid user tag has been dectected; enabling functionality of the device upon receiving the authorization code; and disabling functionality of the device upon receiving a transmission from an interrogator indicating that a valid user tag is not detected.

-
58. A method for selectively enabling or disabling a device having a device tag coupled thereto, the method comprising;
-
detecting a device tag coupled to a device; searching for a valid user tag; performing at least one of the following operations; instructing the device tag to disable the device if a valid user tag is not detected instructing the device tag to enable the device if a valid user tag is detected. - View Dependent Claims (59, 60)

61. A method for selectively enabling or disabling a device having a device tag coupled thereto, the method comprising:
-
detecting a device tag coupled to a device; detecting a valid user tag; analyzing a response signal strength of the device tag and the user tag; estimating a difference between the device tag and the user tag; and determining which of the following operations to perform based on the estimated distance differential; instructing the device tag to disable the device; and instructing the device tag to enable the device. - View Dependent Claims (62)

-
63. A method for selectively preventing disablement of a device having a device tag coupled thereto, the method comprising:
-
detecting a device tag coupled to a device in an active mode using a first interrogator; detecting the device tag in a passive mode using a second interrogator; searching for a valid user tag in a passive mode using the second interrogator; sending an instruction to the device tag to disengage a disabling mechanism that causes disablement of at least some functionality of the device if a valid user tag is detected by the second interrogator, wherein the disabling mechanism causes disablement of at least some functionality of the device if the instruction is not received prior to occurrence of an event. - View Dependent Claims (64, 65, 66)
