Abstract
A payment terminal may include payment interfaces to receive payment information from payment devices such as chip cards and NFC payment devices. Monitoring components may monitor these payment interfaces. In addition, test requests may be transmitted to a payment device in order to elicit responses. The monitored information and the responses may be used by the payment terminal to determine whether a transaction is fraudulent or if a tamper attempt is ongoing, based on local test criteria. In addition, the monitored information and responses may be provided to a server, which may store the monitored information and responses, test for fraudulent transactions and tamper attempts based on server test criteria, and determine updates to the local test criteria.
