FRAUD DETECTION IN A POSTAGE SYSTEM

摘要

A method and system for processing and printing shipping labels having posta ge is described. In one configuration a postage dispensing system allows a shipping label reprint for a relatively short period of time. In another configuration, the system offers a refund after the second unsuccessful prin t attempt and logs the label identifier as an invalid identifier. If the print is successful, the identifier is logged as a successful identifier. The syst em occasionally receives identifiers that have been processed in the mail strea m and reports fraud if an unexpected identifier is present.
