title: Can the UID on a RFID chip be overriden?
body: <p>I'm working on a project where I use RFID chips to identify different units, using the UID on the chip. But a security issue came to mind. Is it anyway possible the override or spoof the UID of a RFID chip? And how is the UID stored on the RFID chip? Is it hardwired(ROM) or is it a part of the general read/write memory storage?</p>
