Claim:
1. A smart check comprising: a first array of organic light emitting diodes (“OLEDs”) forming one or more pixels visible on a first face of the smart check, the first array of OLEDs having a thickness that is not greater than 0.25 mm and having a surface area that is at least 90% of 85.60 mm×53.98 mm; a second array of OLEDs forming one or more pixels visible on a second face of the smart check, the second array of OLEDs having a thickness that is not greater than 0.25 mm and having a surface area that is at least 90% of 85.60 mm×53.98 mm; a rechargeable battery that is not greater than 0.8 mm thick; a contact that extends along one or more sides of the smart check, each side of the smart check having a thickness that is not greater than 0.8 mm, the contact for transferring electrical charge to the rechargeable battery when the smart check is inserted into a card reader; and a processor circuit comprising a non transitory memory and a processor, the processor circuit having a thickness that is not greater than 0.25 mm and the non-transitory memory storing an encrypted value in a first currency; wherein, in operation, when the smart check is inserted into the card reader and electrical charge is transferred from the card reader to the rechargeable battery via the contact: a geographic location associated with the card reader is transferred to the non-transitory memory; second currency information associated with the card reader is transferred to the non-transitory memory; the processor circuit converts the encrypted value into the second currency; and the array of OLEDs is configured to present the location and the second currency on the first face of the smart check.
