A system and method for postage payment utilizes passive RFID tags as postage 'stamps', with the amount of the postage automatically billed to a previously-established customer account. The tags are stored in a separate stamp database and are 'enabled' by linking the individual tag to a customer account. The use of the RFID stamps eliminates the need for the customer to know the proper postage beforehand. The existence of a customer account with a proper return address reduces the likelihood of a dead letter. Also, a special category of stamps may be used for automatic reply mail. By virtue of using an RFID tag, the mailed item's progress through the postal delivery system may be tracked from dispatch to delivery.

An identification tag that is vulnerable to ionizing or non-ionizing radiation and system for determining the presence of radiation based on corrupted or altered memory in the tag is disclosed. An identification tag comprises: a transceiver for receiving an RF signal and transmitting a modulated RF signal; first memory containing a first code for generating the modulated RF signal, the first code being associated with an object for identification; and second memory containing a second code corresponding to a unique identifier for the tag for further modulating the received RF signal, the second memory being specifically vulnerable to ionizing or non-ionizing radiation such that the presence of ionizing or non-ionizing radiation alters or corrupts the second code, wherein the detection of the altered or corrupted code can be employed to indicate the presence of radiation.
