Abstract

A communication device including a digitizer pad and a substrate including a radio frequency tag, where the tag and the digitizer pad are operatively arranged to communicate with each other. A method of communication between a radio frequency identification tag, preferably secured to a business form, and a digitizing tablet.

Claims

1. A communication device, comprising:

a digitizer tablet comprising communication means and a pressure sensitive top surface; and

a substrate comprising a business form and a radio frequency identification tag, wherein said substrate and said digitizer tablet are operatively arranged for communication.

2. A communication device as recited in claim 1, wherein said substrate is made of paper.

3. A communication device as recited in claim 1 wherein said radio frequency identification tag is mounted atop a surface of said substrate.

4. A communication device as recited in claim 1 wherein said radio frequency identification tag is integral with said substrate.

5. A communication device as recited in claim 1 wherein said radio frequency identification tag is flush mounted to said substrate.

6. A communication device as recited in claim 1 wherein said digitizer tablet includes a radio frequency transmitter operatively arranged to transmit a radio frequency signal to said radio frequency identification tag.

7. A communication device as recited in claim 1 wherein said digitizer tablet includes a radio frequency receiver operatively arranged to receive a radio frequency signal reflected from said radio frequency identification tag.

8. A communication device as recited in claim 1 wherein said digitizer tablet includes a radio frequency receiver operatively arranged to receive a radio frequency signal transmitted from said radio frequency identification tag.

9. A communication device, comprising:

a digitizer tablet comprising communication means and a pressure sensitive top surface; and

a substrate comprising a business form and a radio frequency identification tag, wherein said substrate and said digitizer tablet are operatively arranged for communication and said radio frequency identification tag is programmed with information relative to said business form.

10. A method of communication, comprising:

transmitting a radio frequency signal from a transmitter in a digitizer tablet having a pressure sensitive top surface;

reflecting said radio frequency signal from a radio frequency identification tag,

where said radio frequency tag modulates said radio frequency signal to include information; and

receiving said radio frequency signal by a receiver in said digitizer tablet.

11. A method of communication as recited in claim 10 wherein said radio identification tag is secured to a substrate.

12. A method of communication as recited in claim 11 wherein said substrate comprises a business form.

13. A method of communication as recited in claim 10 further comprising the step of demodulating said radio frequency signal.

14. A method of communication, comprising:

transmitting a first radio frequency signal from a transmitter in a digitizer tablet having a pressure sensitive top surface;

receiving said first radio frequency signal by a radio frequency identification tag;

transmitting a second radio frequency signal by said radio frequency identification tag in reply to the reception of the first radio frequency signal; and

receiving said second radio frequency signal by a receiver in said digitizer tablet.

15. A method of communication as recited in claim 14 wherein said radio identification tag is secured to a substrate.

16. A method of communication as recited in claim 15 wherein said substrate comprises a business form.

17. A method of communication as recited in claim 14 further comprising the step of demodulating said radio frequency signal.

18. A communication device, comprising:

a digitizer tablet comprising communication means and a pressure sensitive top surface; and

a paper substrate comprising a radio frequency identification tag, wherein said substrate and said digitizer tablet are operatively arranged for communication.
