Abstract: Systems and methods are provided for adjusting point of sale (POS) interfaces. In some embodiments, a POS device includes a display. The display is configured to present a user interface, the user interface having a first interface and a second interface. The first interface has a first set of functionalities that is prevented from being accessible in the second interface.

Abstract: Methods and systems for processing secure information are disclosed. One method includes receiving secure data from a user via an input device. The method also includes routing the secure data to a secure processor using a hardware multiplexer. The method also includes processing the secure data using the secure processor. The method also includes receiving non-secure data from the user via the input device. The method also includes routing the non-secure data to a second processor using the hardware multiplexer. The method also includes processing the non-secure data using the second processor. The method also includes altering a routing state of the hardware multiplexer using the secure processor. The routing state of the hardware multiplexer is only controlled by the secure processor.

Abstract: A computer-implemented method for an extensible point-of-sale device is disclosed. The method includes registering a third-party application to be notified of a transaction change on the point-of-sale device. The method also includes displaying a user interface to a user during a purchase transaction on a display of the point-of-sale device using one of a register module and a payment module. The method also includes receiving the transaction change via the user interface of the point-of-sale device. The method also includes broadcasting the transaction change to a set of registered applications that includes the third-party application. The method also includes taking an action that modifies the purchase transaction using the third-party application in response to the broadcasting.

Abstract: Systems and methods for efficiently processing a transaction using a point of sale (POS) system and a URL which is provisioned to a purchaser in the transaction are disclosed. A purchase order input for a purchase order for the transaction can be received via a register application on the POS. A payment interface URL is generated and a payment interface for the purchase order is provided at a web page identified by the payment interface URL. Payment authorization is received for the purchase order, from a payment processor, in response to a payment interface input provided on the payment interface. A confirmation of the payment authorization is provided to the register application.

Abstract: Methods and systems related to the use of tokenization services in payment processing systems are disclosed. The methods and systems include token translation services, token maps used as the basis for customer data models, specific approaches for securing the token maps and associated data, and the efficient storage of the token maps and associated data to facilitate enhanced payments experiences and analytics. One method includes transmitting a tokenization request with an encrypted payment account number from a POS to a tokenization service, receiving a token from the tokenization service in response to the tokenization request, salting the token with data to produce a salted token, encrypting the salted token using a secure processor on the POS, mapping the encrypted salted token to the payment account number in a map, and storing the map and the encrypted salted token in a memory on the secure processor on the POS.
