Front & Back Heat Sensitive Ink - Separate Color
The pink thermochromatic 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 disappearing.
Endorsement
The KnightTM, Fingerprint SecurityTM wording & the Fingerprint are printed in pink thermochromatic ink in the endorsement area on the back of the check.
The U.S. Patent numbers are printed on the face of the check in pink thermochromatic ink in the left margin.
ABSENCE OF U.S. PATENT NUMBERS IN THE LEFT MARGIN INDICATES THAT THIS CHECK IS FRAUDULENT. THIS AREA IS PRINTED WITH A PINK HEAT SENSITIVE INK THAT WILL DISAPPEAR WHEN BLOWING OR RUBBING
Watermark Features
The Knight ™ & Fingerprint watermarks are viewable when holding at an angle and also appear when viewed under a blacklight. |
