Abstract: An encoded information reading (EIR) terminal can comprise a microprocessor, a communication interface, an NFC reading device, and an EIR device, all communicatively coupled to the system bus. The EIR reading device can be provided by a bar code reading device, an RFID reading device, or a card reading device. The EIR device can be configured to perform outputting raw message data containing an encoded message or outputting decoded message data corresponding to an encoded message. The EIR terminal can be configured, responsive to completing a decoding operation by the EIR device, to initiate a payment operation using the NFC reading device. The EIR terminal can be further configured, responsive to receiving a response from an NFC tag supporting a payment protocol, to transmit a payment operation request to an external computer.

Abstract: A touch sensitive display device is described. The device has a touch screen and an overlay. The touch screen has a plurality of data entry locations. The overlay has a guide portion and a support portion. The guide portion has one or more apertures and one or more tactile markers, where each of the tactile markers is adjacent to one of the one or more apertures and corresponds to one of the plurality of distinct data entry locations on the touch screen. The support portion if used to retain the guide portion over the touch screen such that each of the one or more guide apertures is in registration with one of the plurality of distinct data entry locations.
