Claims

1. A security system for negotiable instrument operable for automatic scanning and processing in combination with an algorithm system comprising:

a planner member of generally rectangular configuration;

a first field area on said member coated with an invisible fluorescent ink bar code by the printer of said instrument;

a second field area coated with an invisible fluorescent ink;

a second indicia on said second field area;

code means for identifying each of said first and second field areas;

an algorithm combining said first indicia with said second indicia to provide a summation in a numerical format;

a third field area on said instrument to receive sad summation;

said algorithm including means capable of decrypting said summation in a manner to insure that said second indicia comports with said second indicia as originally applied.

2. The security system of claim 1 wherein said second indicia is the payee of said instrument.

3. The security system of claim 2 wherein said second indicia is entered by the maker of said instrument.
