A voucher supply system is provided in which a computerized server of a service provider (1) is configured to store data relating to uniquely identifiable vouchers (6) for distribution through a distribution chain and wherein the vouchers are stored in a storage facility (10) pending distribution. The vouchers are thus stored as inactive vouchers (4) and means (1, 21, 23) are provided for activating such inactive vouchers only at about the time of dispatch thereof from the storage facility or dispatch thereof from a subsequent holder (11, 12, 22) of the inactive vouchers. Preferably, the vouchers are carried on voucher carriers (5) that are uniquely identifiable by way of an additional identifier (8) that is readable electronically by a scanner (17, 21, 23) or other appropriate recognition device. The voucher carriers are typically grouped in uniquely identifiable packets containing multiples thereof and the packets may be grouped with other packets into uniquely identifiable batches thereof. |
