check these out, they are virtually impossible to replicate or alter without fraud being evident. Cool thing is the guy that designed it, Frank Abagnale, was the guy whose was portrayed by leonardo dicaprio in "Catch Me if You Can", the check has a slew of security features and is a very good looking check, far as checks go. We spent months researching security check to get and this was the best there is. I never really cared much for the ones we have been sending out, always wanted to be involved in something that produced beautiful, innovative things.
basically, thats the big thing, here are some others: Overt Security Features: Fourdrinier Watermark: There is a Fourdrinier (true) watermark that is pressed into the paper at the mill and is visible from either side when held to the light. This dual-tone watermark provides instant authenticity of the document and is virtually impossible to replicate, copy or scan. Thermochromatic Ink: On the back of the check there is a seal printed with thermochromatic (heat-sensitive) ink that changes colors when heated. This thermochromatic seal can be rubbed for instant authentication of the check. Color copiers cannot reproduce the reactivity of thermochromatic ink. High-Resolution Borders: The check is engineered with intricately designed borders that are difficult to duplicate. High-resolution borders are ideal for covert security because the design often distorts when copied. Microprinting: There is printing so small that it appears as a broken line or pattern to the human eye. When scanned or photocopied, microprinting will often blur on the copy. Chemical Wash Detection Boxes: On the back of the check, there is specially designed box engineered to deter check washing. The check is sensitive to over 80 chemicals, and the box makes chemical tampering instantly evident. Prismatic Printing: The background is designed of subtle gradations between multiple colors. This level of color distinction is difficult to reproduce on most color copiers. Laid Lines: Lines of varying width and spacing are printed on the back of each check to deter cut-and-paste alterations. Warning Banner: There is a warning banner that explicitly describes specific overt security features and advises the recipient to look for these features before accepting the check. This warning banner may also deter a forger from "experimenting" with the check. Covert Security Features: Controlled Paper Stock: The check is manufactured using imported premium-grade security paper. This paper is not available in America, except as the Check, making it nearly impossible for a forger to replicate the check. The paper contains a true watermark, is reactive to 85 chemicals, and is extremely tightly controlled. Chemically Reactive Paper: The check reacts to 85 different chemicals. When chemically washed, the Check and its chemical wash detection box discolor, and no longer look like the original document. Ultraviolet Light-Sensitive Ink: Under UV light, the word "AUTHENTIC" appears on the check, which serves to authenticate the check as original. Ultraviolet Light-Sensitive Fibers: The imported paper used contains ultraviolet light-sensitive fibers that fluoresce under UV light and further serve as an authentication tool.
Well, damn me! I wonder how much it cost to develop all that... and how much each check book costs to produce!
