SYSTEM FOR VERIFYING AUTHORIZED USE OF A CREDIT CARD OR THE LIKE
First Claim
1. A system for reading a first coded set of coded identification indicia visible to the human eye associated with a credit card or the like and for reading a second set of identification indicia which is invisible to the human eye and which is associated with a credit card or the like and for varifying authorized use thereof comprising:
- means for scanning said first and second coded sets of identification indicia with a spot of light;
a transducer positioned adjacent said credit card or the like for converting light intensity emanating from said card as said coded sets of identification indicia are scanned into signals corresponding to said light intensity;
a three-level discriminator coupled to said transducer for producing a first electrical signal when said spot of light is congruent with an opaque bit upon said credit card or the like, for producing a second electrical signal when said spot of light is congruent with a non-opaque bit and for producing a third electrical signal when said spot of light is congruent with a bit position which fluoresces in response to being struck by said spot of light;
first storage means coupled to said three-level discriminator for storing said first coded set of identification indicia read off of said credit card or the like;
second storage means coupled to said three-level discriminator for storing said second coded set of identification indicia associated with said credit card or the like; and
first comparator means coupled to said first and second storage means for indicating whether or not the coded sets of identification indicia stored within said first and second storage means correspond with each other.

Abstract
A system is disclosed for machine scanning a first and second set of identification indicia recorded upon a credit card or the like wherein said first set of identification indicia is visible to the human eye and a second set of identification indicia is invisible to the human eye. Circuitry is provided for comparing the visible and invisible sets of identification indicia to determine whether or not they correspond, lack of correspondence thereof indicating the possible presence of a counterfeited card. Further circuitry is provided for having a bank teller, for example, manually insert the card holder'"'"''"'"'s identification number, which is orally transmitted to the teller by the card holder, into the system whereby the manually inserted identification number is compared with the machine scanned coding associated with the card. If all three codes correspond, it is extremely unlikely that unauthorized use of the credit card is occurring or that coded indicia has been misread by the scanner.
