摘要

A sender stamps a combined postage-cum-ID stamp on his letter. Postage value can be adjusted on the stamp. An ID specific to the sender/customer is deposited in a letter-sorting office computer for a letter-dispatch business and given an ID in the event of any loss. The ID specific to the sender is printed on a chip card to be inserted by the customer into the stamp.
