Abstract: Articles and methods for transaction irregularity detection are disclosed. In one example, the article discloses: a memory including a record of a last-reported security-device transaction with the security-device, and including a last-reported transaction counter value associated with the last-reported security-device transaction; a previous device identifier; a record of the previous security-device transaction with the security-device, and including the previous device identifier associated with the previous security-device transaction; a record of a current security-device transaction with the security-device, and including a currently-reported transaction counter value associated with the current security-device transaction; and a back-end device tagging the previous device with fraud if the current transaction counter value differs from the last-reported transaction counter value by other than an increment. In one example, the method discloses: a transaction irregularity detection process based on the article.

Abstract: The disclosure relates to dynamic secure messaging using near-field communication. Example embodiments include a near field communication target device (102) configured to respond to a read request (202) transmitted by a reader device (101) by transmitting a message (204) comprising an unencrypted portion and an encrypted portion, the encrypted portion incorporating a counter that is incremented each time a read request is received.

Abstract: There is described a method of checking whether a transponder device (220) is in proximity of a reader device (210), the method comprising (a) transmitting a first command (331) from the reader device to the transponder device, (b) in response to receiving the first command at the transponder device, transmitting a first response (332) to the reader device, the first response including an expected transponder device response time (pubRespTime) which is stored in a memory (224) of the transponder device, (c) transmitting a second command (333) from the reader device to the transponder device, (d) in response to receiving the second command at the transponder device, transmitting a second response (334) to the reader device, (e) at the reader device, determining the transponder device response time as the difference in time between transmitting the second command and receiving the second response from the transponder device, and (f) determining whether the determined transponder device response time matches the expected transponder device response time included in the first response. There is also described a reader device (210), a transponder device (220), and a contactless communication system (200).
