Coin-discriminator voucher anti-counterfeiting method and apparatus
View Patent ↗Vouchers and methods for providing vouchers configured to assist in distinguishing unauthorized duplicate or counterfeit vouchers are disclosed herein. In one embodiment, a voucher can include a substrate, a first indicia on the substrate, and a thermally responsive second indicia on the substrate. At least one of the first indicia and the second indicia can indicate a value of the voucher. A system which assists in detecting alteration of value documents or transmissions, such as a coin counter voucher is provided. Voucher information such as the voucher value is included in the voucher in an encrypted or otherwise modified form. When the voucher is presented for redemptions, the encrypted information is decrypted and compared to independently available voucher information. Failure of the information to match indicates that the voucher has been altered or should otherwise be further checked.

6. The method of claim 1 wherein the plurality of coins is a first plurality of coins, wherein the total is a first total, wherein the portion of voucher substrate is a first portion of voucher substrate, wherein the at least one preprinted serial number is a first preprinted serial number, and wherein the method further comprises:
counting a second plurality of coins in the coin counting machine to determine a second total;
printing a value related to the second total on a second portion of voucher substrate in the coin counting machine, wherein the second portion of voucher substrate includes a second preprinted serial number different from the first preprinted serial number;
printing a second identifier number on the second portion of voucher substrate proximate to the second preprinted serial number, wherein the second identifier number matches the second preprinted serial number; and
dispensing the second portion of voucher substrate from the coin counting machine.
7. The method of claim 1 , further comprising:
encrypting transaction-identifying information, wherein the transaction-identifying information is associated with the coin counting transaction; and
printing the encrypted transaction-identifying information on the portion of voucher substrate.
8. The method of claim 1 , further comprising:
encrypting the value by permuting the digit order of a number which includes the value to provide a first permuted number;
printing the encrypted value on the portion of voucher substrate;
decrypting the encrypted value; and
redeeming the substrate for at least one of cash and merchandize up to the value.
9. The method of claim 8 wherein permuting the digit order is performed with a permutation vector.
10. The method of claim 8 wherein encrypting the value includes adding a selected number to the permuted number.
11. A coin counting machine comprising:
a computer;
a coin discriminator operably connected to the computer, wherein the coin discriminator is configured to count a plurality of coins to determine a total;
a voucher printer operably connected to the computer; and
a voucher substrate loaded into the voucher printer:
wherein the voucher substrate includes a plurality of preprinted serial numbers preprinted along the length of the voucher substrate;
wherein the plurality of preprinted serial numbers includes at least a first preprinted serial number;
wherein the computer controls the voucher printer to print an identifier number on a portion of the voucher substrate proximate to the first preprinted serial number prior to dispensing the portion of voucher substrate from the coin counting machine; and
wherein the identifier number matches the first preprinted serial number.
12. The coin counting machine of claim 11 :
wherein the plurality of preprinted serial numbers further includes a second preprinted serial number different than the first preprinted serial number;
wherein the identifier number is a first identifier number;
wherein the computer controls the voucher printer to print a second identifier number on the portion of voucher substrate proximate to the second preprinted serial number prior to dispensing the portion of voucher substrate from the coin counting machine; and
wherein the second identifier number matches the second preprinted serial number.
13. The coin counting machine of claim 11 wherein the plurality of preprinted serial numbers change in a preset manner along the length of the voucher substrate.
14. The coin counting machine of claim 11 :
wherein the computer is configured to encrypt a value related to the total of coins counted by permuting the digit order of a number which includes the value to provide a first permuted number; and
wherein the computer further controls the voucher printer to print the encrypted value in machine-readable form on the portion of voucher substrate prior to dispensing the portion of voucher substrate from the coin counting machine.
15. The coin counting machine of claim 14 wherein the computer is configured to permute the digit order with a permutation vector, and wherein the computer is further configured to encrypt the value by adding a selected number to the permuted number.
