Abstract

A radio frequency identification device includes an attachment means which is maintained in operative relationship with an object or individual by securement means. The attachment means is disposable and the securement means is easily separable therefrom for reuse, the securement means including a radio frequency identification (RFID) circuit which can be reused after the attachment means has been disposed of. One form of the radio frequency identification device is an identification wristband which incorporates attachment means and securement means for said attachment means, the securement means incorporating an RFID such as a chip which is removed from operative relationship with the attachment means when the securement means is removed to permit reuse of the securement means and chip.

Claims

1. A radio frequency identification device, comprising:

attachment means including an elongated and disposable flexible first strap having first and second opposite ends and having a fastening opening in at least one of said ends;

securement means incorporating a fastening element engageable with said fastening opening of said first strap to removably connect said securement means thereto, and to configure said first strap generally in a closed loop configuration encircling and thus retained on a first object or individual to be identified; and

a radio frequency identification circuit carried by said securement means and programmable for receiving and storing information associated with the first object or individual;

said securement means being removable from said first strap to accommodate removal of said first strap from the first object or individual for disposal, and, upon such removal, said fastening element of said securement means being thereupon engageable with a fastening opening of a second strap having first and second opposite ends, to removably connect said securement means thereto, and to configure said second strap generally in a closed loop configuration encircling and thus retained on a second object or individual to be identified; and

said radio frequency identification circuit being re-programmable for receiving and storing information associated with said second object or individual.

2. The radio frequency identification device of claim 1, wherein said first and second straps each include an antenna, and further comprising coupling means for operatively and removably connecting said antenna with said radio frequency identification circuit when said securement means is connected respectively to said first or second strap, and for disconnecting said antenna from said radio frequency identification circuit when said securement means is respectively disconnected from said first or second strap.

3. The radio frequency identification device of claim 2, wherein said antenna on each of said first and second straps is formed from conductive ink.

4. The radio frequency identification device of claim 2, wherein said antenna on each of said first and second straps is formed from a material selected from the group including organic and polymeric materials.

5. The radio frequency identification device of claim 1, wherein said radio frequency identification circuit is embedded within said securement means.

6. The radio frequency identification device of claim 1, wherein said fastening element on said securement means comprises a boss, and wherein said first end of each of said first and second straps is removably connectable to said boss, said securement means further defining an opening extending therethrough for slide-fit passage of said second end of said first and second straps for respectively configuring and retaining said first and second straps in a generally closed loop shape.

7. The radio frequency identification device of claim 6, wherein said second ends of said first and second straps are adjustably retained within the securement means.

8. The radio frequency identification device of claim 1, wherein said fastening opening in said first and second straps comprises at least a a pair of fastening openings formed respectively at said first and second ends.

9. The radio frequency identification device of claim 8 wherein each of said first and second straps comprises an elongated tubular band.

10. The radio frequency identification device of claim 8, wherein said first and second straps each include an antenna carried generally at said first end thereof for operative connection with said radio frequency identification circuit when said first extremity of said securement means is received into the opening at said strap first end.

11. The radio frequency identification device of claim 10, wherein said first end of each of said first and second straps is marked to indicate the location of said antenna.

12. The radio frequency identification device of claim 8, wherein each of said first and second straps each include an antenna extending substantially the entire length thereof and defining opposite ends at said first and second strap ends for respective operative connection with said radio frequency identification circuit when said first and second extremities of said securement means are received respectively into the openings at said first and second strap ends.

13. A radio frequency identification method, comprising the steps of:

providing a plurality of elongated and disposable flexible straps for respective mounting onto a corresponding plurality of objects or individuals to be identified;

providing a securement means incorporating a radio frequency identification circuit programmable for receiving and storing information associated with any one of the plurality of objects or individuals to be identified;

removably connecting the securement means with a first one of the straps to configure and retain the first strap generally in a closed loop configuration encircling and thus retained on a first one of the objects or individuals to be identified for the duration of a first use cycle;

programming the radio frequency identification circuit with information associated with the first object or individual;

disconnecting the securement means from the first strap at the conclusion of said first use cycle to accommodate removal of the first strap from the first object or individual for disposal;

following said disconnecting step, removably connecting the securement means with a second one of the straps to configure and retain the second strap generally in a closed loop configuration encircling and thus retained on a second one of the objects or individuals to be identified for the duration of a second use cycle; and

re-programming the radio frequency identification circuit with information associated with the second object or individual.

14. The method of claim 13, further including the steps of incorporating an antenna into each of the straps, and coupling the radio frequency identification circuit with the antenna upon respective connecting of the securement means with each of the straps, and disconnecting the radio frequency identification circuit from the antenna upon respective disconnecting of the securement means from each of the straps.

15. The method of claim 14, wherein each of the straps has a first end and a second end, and further including the steps of incorporating the antenna into each of the straps at the first end thereof, and marking the strap to indicate the location of the antenna.

16. The method of claim 14, wherein each of the straps has a first end and a second end, and wherein the antenna extends substantially the entire length thereof and defines opposite ends generally at the first and second strap ends, said coupling step comprising the step of operatively connecting the opposite ends of the antenna with the radio frequency identification circuit by coupling the first and second strap ends respectively with first and second opposite extremities of the securement means.

17. The method of claim 14, wherein the antenna on each of the straps is formed from conductive ink.

18. The method of claim 14, wherein the antenna on each of the straps is formed from a material selected from the group including organic and polymeric materials.

19. The method of claim 13, further including the step of embedding the radio frequency identification circuit within the securement means.
