Abstract: A method and machine for verifying or validating coupons wherein the method comprises passing at least two juxtaposed coupons, each of which has a bar code printed or formed thereon, through or relative to a bar code reader, such that the juxtaposed coupons if accepted by said bar code reader cause matter to be dispensed from a holding and dispensing device. In the machine for verifying or validating coupons, a bar code reader adjacent the inlet, a holding and dispensing device and a programmed processor are also provided within the housing. The arrangement is such that on at least two juxtaposed coupons being passed into and through said bar code reader substantially simultaneously, and being accepted thereby, a predetermined or desired amount of matter is caused to be dispensed from said holding and dispensing device.
