Abstract
A self-diagnosing validation device includes an NFC reader having an RF signal range, an active diagnostic chip positioned within the RF signal range of the NFC reader, a memory, and a processing unit. The active diagnostic chip is configured to be selectively powered during a diagnostic procedure. The processing unit is configured to determine that the diagnostic procedure needs to be performed on the NFC reader and perform the diagnostic procedure. The diagnostic procedure includes activating the active diagnostic chip by supplying power to the active diagnostic chip, reading, using the NFC reader, any data being transmitted by the active diagnostic chip, determining whether any data was read by the NFC reader, and determining whether the NFC reader is functioning properly based at least in part of the determination whether any data was read by the NFC reader.
