Abstract: An offline code-based reload device and method for adding value to a reconfigurable memory storage means in a portable storage medium. Reload is effected using a reload device not directly connected by telephone or any other communication network to a value supplier. The system uses a “one time use number” (“OTN”) generated by a computer program containing an algorithm containing information on the value to be added and a transaction sequence number (“TSN”). Upon presentation of the portable storage medium to the reload device and entry of the OTN into a numeric keypad, the reload device decodes or disassembles the OTN to verify its authenticity, validate that it was created for the specific portable storage medium presented to the reload device and to verify through the TSN that the OTN has not been previously used to add value from the receiving reload device or any other reload device.

Abstract: This invention concerns a cashcard system for purchasing laundry services wherein the user is issued with a cashcard and a personal identification number. Each of the laundry facilities is provided with a terminal having means for verifying the user, means for verifying the card, means for updating the card with an amount requested by the user, means for saving the card identification and the amount revalued to the card and means for storing and forwarding at a later time the amounts revalued to the cards for credit verification by a central computer remote to the terminal. In addition, the terminal in verifying the card compares the card to a previously rejected cards before updating the card with a new amount requested.
