    • Conventional use of card readers is in a situation where the card is returned to the user, e.g. a cash dispenser at a bank. The card is not normally retained by the card reader. When used as a token to pay for use of games apparatus, however, the card is not returned. A problem arises in prior proposals in that once the machine has registered a credit on acceptance of a card, it has been possible to withdraw the card by a piece of string, previously attached, whilst still retaining the credit. Of course the card may then be fraudulently reused many times and the winnings retained by the player. The application discloses safeguards to resist the withdrawal of a card, to signal an alarm if a card is withdrawn and to prevent receipt of a token being credited if the card is withdrawn.
