Abstract
A display enabled RFID tag (DERT) receives transaction details from the reader. DERT verifies that the details match their counterparts in the reader public key certificate. The process is aborted in case of a mismatch. DERT extracts and displays user-verifiable data. It then enters a countdown stage that lasts for a predetermined duration. A user observes the transaction information and, if the transaction amount and other details are deemed correct, presses an accept button provided on the DERT before the timer runs out. DERT signs the time-stamped transaction statement and sends it to the reader. This signed statement is then sent to the payment gateway and eventually to the financial institution that issued the payment DERT.
