In one embodiment, a two-portion cash-dispensing machine has a first secure portion that receives paper currency during bill-breaking operations and vouchers during voucher-redemption operations and a second secure portion that dispenses paper currency. Physical access to the first secure portion is restricted to authorized first agents, and physical access to the second secure portion is restricted to authorized second agents. Physical access to the first secure portion by an authorized first agent does not inherently provide physical access to the second secure portion by the authorized first agent, and vice versa. In one application, two different business entities are respectively responsible for maintaining the two different secure portions, and the machine communicates information associated with requests for transfers of funds from a bank account of the first entity to a bank account of the second entity to reimburse the second entity for bill-breaking and voucher-redemption operations.
