Abstract

Abstract A data card which can be encoded by the user without special encoding facilities has a substrate with a first light reflection characteristic. The substrate carries a code field embracing all possible ''''bit'''' locations in the code. Selected bit areas in the field are treated to give them a different light reflection characteristic from the substrate in the remainder of the field, thereby impressing a code pattern in the code field consisting of ''''bit'''' locations having one of two different light reflection characteristics.

Claim 17
Dependent Claim 72 words
The method of making a data card as defined in claim 4 and including the additional step of removing the tape strips from selected ones of the depressions in accordance with written instructions so as to create a code pattern on the card surface consisting of the depressions containing no tape strips and having the first light reflection characteristic and the depressions containing tape strips and having the second light reflection characteristic.
