An apparatus for issuing a transaction card comprises a value receiving mechanism in the form of a card reader or a bank note acceptor or both. The apparatus includes a memory for storing the exchange rate for a plurality of currencies as compared to a local visitor's voucher which can be issued by the apparatus. A mechanism is also provided for storing a maximum transaction limit corresponding to a selected number of visitor's vouchers, which in turn corresponds to value of currency received. The transaction card is advantageously a smart card or chip card, which carries a program mechanism and central processing unit for manipulating the values which can be stored in the card.
