ABSTRACT:
An identification document which includes card specific information printed on the card in a first location at a relatively large scale which permits the information to be read without magnification and duplicates the card specific information at a second location on the card at a significantly smaller scale which requires magnification to clearly read the small scale information. The micro-printing of small scale card specific information, such as a person's date of birth on a driver's license, at a second location on the identification card allows the micro-printed text to be compared to the large scale text to determine if the large scale text has been altered.
