ABSTRACT:
A system for detecting fraudulent imprints on documents is disclosed. The system comprises a metering device, a host and a verifying facility. The metering device provides a validation signal to the host and its associated printer. Thereafter, the printer prints information which includes information from the validation signal. Thereafter the information printed on a mailpiece can be validated at the verifying facility by detecting the validation information provided by the metering device. The system provides a method to make a secure metering device without an integral printer. This value printing system provides for a secure system that will allow for the detection of fraudulent imprints at a verifying facility.
