Abstract
A system for auditing coupon distribution in a retail store. The system includes a plurality of retail stores, each having a coupon-dispensing unit for writing electronic coupons onto portable IC cards carried by each customer. To audit the system, store personnel insert an auditing card into the coupon-dispensing units, to collect the dates and recipients of coupon-dispensing transactions.
