Abstract

A method and system for electronically recording and authorizing a transaction utilizes an electronic reading device for generating an electronic reproduction of written information by detecting positions of the electronic reading device relative to a particular address pattern in a data entry field of a formatted surface. The electronic reproduction of the written information is sent to a server that stores or processes the electronic reproduction. For example, the server can determine whether the electronic reading device is authorized to use the particular address pattern or whether the electronic reproduction correlates with stored data. In addition, to enable the electronic reading device, detection of a correct user personal identification number (PIN) or user fingerprint may be required.

Claims

1. A system for electronically recording a transaction, comprising:

a formatted surface including a data entry field that includes an address pattern;

an electronic reading device including a position sensor for detecting positions of the electronic reading device relative to the address pattern as information is written in the data entry field, wherein a unique position on the address pattern is identified from an examination of a portion of the address pattern, and wherein the positions of the electronic reading device are used to generate an electronic reproduction of the written information; and

a server for receiving the electronic reproduction of the written information.

2. The system of claim 1, wherein the formatted surface comprises a negotiable instrument.

3. The system of claim 2, wherein the server further stores the received electronic reproduction in connection with a user account associated with the electronic reading device.

4. The system of claim 2, wherein the data field comprises a signature field, the server further operating to compare the electronic reproduction of the written information with a stored user signature.

5. The system of claim 4, wherein the server authorizes a transaction if the electronic reproduction corresponds to the stored user signature.

6. The system of claim 2, wherein the server authorizes a transaction based on a determination of whether the formatted surface is allocated for use in connection with the electronic reading device.

7. The system of claim 1, wherein the data field comprises a personal identification number (PIN) field, the server further operating to compare the electronic reproduction of the written information with a stored PIN.

8. The system of claim 1, wherein the electronic reading device ciphers the electronic reproduction of the written information for transmission to the server.

9. A method for electronically recording a transaction, comprising the steps of:

detecting a plurality of positions of an electronic reading device with respect to a particular address pattern on a formatted surface, said plurality of positions corresponding to information written on the formatted surface with the electronic reading device;

identifying a unique position on the address pattern from an examination of a portion of the address pattern;

determining whether an identifier for the electronic reading device is associated with the particular address pattern; and

establishing whether the written information is valid based on said determination.

10. The method of claim 9, wherein the formatted surface comprises a negotiable instrument.

11. The method of claim 10, wherein the written information comprises a signature, the method further comprising the step of correlating the plurality of positions with stored signature data.

12. The method of claim 10, further comprising step of sending the plurality of positions to a server for providing confirmation of the negotiable instrument.

13. The method of claim 9, further comprising the step of enabling the electronic reading device only if a personal identification number (PIN) written with the electronic reading device corresponds to stored PIN data.

14. An electronic reading system, comprising:

an electronic reading device including a position sensor for detecting positions of the electronic reading device relative to an address pattern on a formatted surface, wherein a unique position on the address pattern is identified from an examination of a portion of the address pattern;

a memory for storing a preselected code; and
