Abstract
An apparatus is provided, including a transaction card, having: a first microprocessor configured to exchange transaction data; a sensor configured to detect movement; and a second microprocessor in communication with the sensor. The second microprocessor may be configured to store arrays of hash values, representing a movement of a user and a card; obtain hash values based on observed movement patterns, and compare them to the stored values. Upon receiving a transaction request, the microprocessor may determine in real time whether the user is in locomotion and whether the card is being intentionally tapped by the user, based on the observed movement patterns. On this basis, the second microprocessor may determine whether to require an augmented authentication for the requested transaction.
