Open the CIPO recordAbstract From the Canadian patent
Currency is validated by comparing (35) identifying information extracted (33) from the currency such as a serial number associated with the currency to identifying information in a list corresponding to invalid currency such as counterfeit currency. If the extracted identifying information matches (38) identifying information on the list the currency is deemed invalid. A photograph or thumbprint image can be obtained by a person using the invalid currency to help in later identification of that individual. Optical character recognition techniques can be used to extract the identifying information.
