Abstract

An RFID device includes a first, relatively permanent portion and a second alterable or inactivatable portion. Upon the occurrence of some predetermined event, the second portion and/or its coupling to the first portion is physically altered, inactivating it. The first portion may itself be an antennaless RFID device that may be read at short range, and the second portion may be an antenna that, when coupled to the first portion, substantially increases the range at which the first portion may be read. The second portion may be configured to be altered or inactivated by any of a variety of predetermined events, such as involving physical, chemical or electrical forces, performed either on the RFID device, or upon an object to which the RFID device is coupled.

Claims

1-37. -37. (canceled)

38. A radio frequency identification (RFID) device, comprising:

an RFID device including a transponder chip;

an antenna coupled to the chip;

a power supply is coupled to the RFID device; and

wherein the power supply alters a function of the RFID device when the power supply is activated.

39. The device of claim 38, wherein a low current power is the power supply for the RFID device

40. The device of claim 38, wherein the power supply is coupled to the antenna through at least one RF choke section.

41. The device of claim 38, wherein the power supply is a 12-volt power supply.

42. The device of claim 38, wherein the power supply provides a higher voltage to power electroluminescence backlights on telephones and computers

43. The device of claim 38, wherein the power supply alters the function of the function of the RFID device via a fusible link between the antenna and an electrical system ground.

44. The device of claim 38, wherein a current supply causes the antenna to burn out at least a portion of the antenna.

45. The device of claim 43, wherein the fusible links become open circuits upon application of power to the antenna.

46. The device of claim 40, wherein the RF choke section is a fusible link.

47. A radio frequency identification (RFID) device, comprising;

a stretchable substrate;

a conductive trace disposed on a portion of the substrate to create an alterable portion;

an antenna and a chip connected to the antenna; and

wherein upon stretching the substrate the alterable portion deactivates the RFID device.

48. The device of claim 47, wherein the stretchable substrate is selected from a group including polyolefins, paper or combinations thereof.

49. The device of claim 47, wherein the alterable portion includes at least one of an indentation or perforations.

50. The device of claim 47, wherein alterable portion includes a fusible link.

51. The device of claim 47, wherein the conductive trace is a conductive ink.

52. The device of claim 51, wherein the conductive ink is silver ink.

53. A radio frequency identification (RFID) device, comprising:

a substrate;

a transponder chip; and

an antenna coupled to the chip and the antenna has a one or more soluble conductive links integral therewith; and

wherein removal of at least one of the soluble conductive links of the antenna changes electrical characteristics of the antenna.

54. The device of claim 53, wherein the substrate includes a printable layer displaying text, and/or graphics.

55. The device of claim 53, wherein the substrate is a flexible polymeric material

56. The device of claim 54, wherein a laminate is provided over the text and/or graphics.

57. The device of claim 53, wherein the soluble conductive links is removed by washing.
