Abstract
Arrangements for providing unauthorized activity detection are provided. A computing platform may receive an indication that a transaction has been initiated at a transaction processing device. The platform may receive, from one or more sensors arranged on the transaction processing card, magnetic field data associated with a magnetic field detected when the transaction processing card is inserted into the card reader. The platform may execute a machine learning model using, as inputs, the magnetic field data, to output any detected discrepancies between the current magnetic field data and expected magnetic field data. If a discrepancy is detected, the computing platform may identify that a shimming device is present at the card reader of the transaction processing device. A notification indicating that the shimming device is present may be generated and transmitted to, for instance, the transaction processing card.
