A payment reader and a POS terminal may communicate over a wireless connection. The methods and systems include receiving, from POS terminal, a request for establishing a network connection with the payment card reader. The server determines whether the payment card reader is associated with the POS terminal or a payment application thereon. If the payment card reader is not associated with the POS terminal or the payment application thereon, the server determines the probability of the request being fraudulent.

Fraud detection in portable payment readers

A payment reader and a POS terminal may communicate over a wireless connection. An original state of the payment reader can be used to determine a behavioral model, wherein the behavioral model defines an expected behavior of the payment entity. The system and method include detecting a change in the original state of the payment entity, wherein the change in the original state is triggered by another payment entity not authorized by the merchant; comparing the change of the original state with a threshold deviation defined by the behavioral model; and if the change of state is not within the threshold deviation, performing one or more actions to revert the payment entity to the original state.
