  • Publication number: 20200202357
    Abstract: A payment processing device can implement a monitoring system to detect for tamper attempts at a chip card interface. The monitoring system can establish a baseline when no chip card is present in the chip card interface, or in some embodiments, when it is known that an authentic chip card 14 is present in the slot 21. During subsequent evaluations of the chip card interface by the monitoring system, a response received by the monitoring system that deviates from the baseline can indicate that a tamper attempt at the chip card interface may have occurred. If a tamper attempt is determined by the monitoring system, a remedial or corrective action can be taken.

  • Publication number: 20200065817
    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.

  • Patent number: 10572695
    Abstract: A tamper-proof computing device used in conducting a point-of-sale transaction. The tamper-proof computing device comprises a touch-screen display. In some embodiments, an ITO layer is deposited on the touch-screen display that has a tamper line embedded in the ITO layer, such that the tamper line is susceptible to breaking upon unauthorized physical manipulation, and the tamper line is in communication with a microcontroller that is configured to detect the tamper, and to render the tamper-proof computing device inoperable. The tamper line can be a single line trace embedded in the ITO layer or a cluster of traces embedded in the ITO layer. A method of manufacturing comprises forming a tamper line in an ITO layer, depositing the ITO layer on the display and coupling the tamper line to a security microcontroller.

  • Patent number: 10438189
    Abstract: A payment processing device can implement a monitoring system to detect for tamper attempts at a physical interface such as a chip card interface. The monitoring system can establish local tamper criteria including a baseline when no chip card is present in the chip card interface, or in some embodiments, when it is known that an authentic chip card is present in the slot. During subsequent evaluations of the chip card interface by the monitoring system, a response received by the monitoring system that deviates from the local test criteria can indicate that a tamper attempt at the chip card interface may have occurred. The payment processing device may also communicate test results to a server for further testing, or for an update of the local test criteria.

  • Publication number: 20190004785
    Abstract: This disclosure describes, in part, techniques for securely updating a point-of-sale (POS) system that includes a merchant-facing device and a buyer-facing device. For instance, the merchant-facing device may execute first software that provides first POS functionality and the buyer-facing device may execute second software that provides second POS functionality. To update both devices, the merchant-facing device may receive a software update from a payment service via a network connection, and update the first software using the software update. The merchant-facing device can then cause, via a physical connection, the buyer-facing device to reboot in an update mode and send the software update to the buyer-facing device. In response, the buyer-facing device can update the second software using the software update and then reboot in a payments mode. In some instances, the buyer-facing device can then update a secure enclave on the buyer-facing device using the software update.

  • Publication number: 20170091762
    Abstract: A wireless communication device such as a payment reader has a wireless communication interface and is able to establish wireless pairing with an interactive electronic device such as a merchant device running a point of sale application. In order to establish pairing, the wireless communication device accesses a passkey and encrypts the passkey. The encrypted passkey is transmitted to the interactive electronic device via the wireless communication interface, and the interactive electronic device sends the encrypted passkey to a pairing server. The pairing server decrypts the encrypted passkey and sends the decrypted passkey back to the interactive electronic device via a secure connection. The wireless communication device and the interactive electronic device establish wireless pairing based on the passkey and the decrypted passkey.

  • Publication number: 20170091732
    Abstract: A wireless communication device such as a payment reader has a wireless communication interface and is able to establish wireless pairing with an interactive electronic device such as a merchant device running a point of sale application. In order to establish pairing, the wireless communication device accesses an identifier. The identifier is transmitted to the interactive electronic device via the wireless communication interface, and the interactive electronic device sends the identifier to a pairing server. The pairing server retrieves a passkey based on the identifier and sends the retrieved passkey to the interactive electronic device via a secure connection. The wireless communication device and the interactive electronic device establish wireless pairing based on the retrieved passkey.
