2. Signature Area & Amount Line
   U.S. Patent
   The signature area and amount line are printed with the different pantographic backgrounds from the front of the check.

The signature area also has a warning clause indicating that the signature has a colored background.

3. Micro Printing

4. ABA Check Endorsement Clause
   U.S. Patent
   The American Banking Association (ABA) endorsement clause is printed on the back of the document with a warning clause indicating that the face of the check contains a colored background, a facsimile of the watermark, etc. The checks pantographic background is also part of the endorsement clause.

5. Watermark Certification Seal
   U.S. Patent
   An EPA approved watermark certification seal & fingerprint that cannot be photocopied are on the back of every check with appropriate warning clauses printed on the front and back of the check. The watermark(s) also certifies that the paper meets all specifications for laser check printing.

6. Heat sensitive Ink - Separate Color
   U.S. Patent
   The patented ink will disappear at temperatures above 85� F. This will allow the payer to verify that the check is not a fraudulent document. Because the ink is heat sensitive it is virtually impossible to make copies or scan the document without the fingerprint and security seal disappearing.

7. Fingerprint Watermark Security Seal
   U.S. Patent
   In addition to the visible fingerprint security seal in the ABA endorsement area, the same fingerprint and seal are incorporated in the watermark(s) to further guarantee the authenticity of the negotiable document.

8. Warning Clause
   U.S. Patent
   The ABA endorsement area also contains the FingerprinTsecurIty warning clause to alert the payer that rubbing or breathing on the heat sensitive ink will make the ink temporarily disappear.

9. Fluorescent Fibers
   Artificial yellow fluorescent fibers on the back will intensify under black light.

10. Control Numbers
    Each FingerprinTsecurIty check is printed with a control number to further assure authenticity. These numbers, along with the fingerprint, are registered with FingerprinTsecurIty, Inc.(Available for additional charge)
