Abstract: A system for accepting the input of a PIN comprises a first device receiving a randomized PIN layout derived on a fourth device. The randomized PIN layout is displayed on a display of the first device. A second device comprises an input for accepting a series of key presses to produce a PIN token. The PIN token indicating each of the series of key presses. A third device is in communication with the second device. The third device derives the randomized PIN layout and receives the PIN token from the second device without the PIN token being present on the first device. The third device combines the PIN layout and the PIN token to produce a PIN. The PIN is used to authenticate a transaction. The fourth and third devices each store a shared secret used to independently derive the randomized PIN layout on the fourth and third devices.

Abstract: Installing and running an application for a terminal are described. A method for installing and running the application includes uploading an application to an application store. The method further includes downloading, by a terminal, the application from the application store, wherein the terminal is connected to the application store by a network. Furthermore, the method includes authorizing, by a terminal management server (TMS) coupled to the terminal and the application store via the network, the terminal to install and run the downloaded application.

Abstract: A contactless card reader comprises a contactless card reader front-end coupled to a processor. A communications module is coupled to the processor and a set of sensors is coupled to the processor. The set of sensors determines parameters related to the location, orientation and motion of the card reader. The processor receives the parameters from the set of sensors and utilizes the parameters and scenario configuration data to evaluate a rule. The result of the evaluation of the rule results in a limitation on the operation of the card reader. The communications module is configured to intermittently receive the scenario configuration data from external sources.

Abstract: A card detection subsystem for control of a payment card reader, where the payment card reader comprises a magnetic stripe reader (MSR), an integrated circuit card (ICC) reader, and a near field communications (NFC) reader, and the NFC reader comprises an antenna. The card detection subsystem includes a processor, a storage, and one or more sensors. The one or more sensors detect a payment card and the antenna is either turned on or turned off based on the detection of the payment card.
