Abstract: A method for processing transaction data, implemented by a communications terminal having a touch screen. The method includes: detecting a necessity of entering a piece of personal identification data; transmitting to a card reader connected to the communications terminal a request for supporting a display of a virtual keypad, the request comprising a piece of data representing a passage of the communications terminal from a “master” mode to a “slave” mode of operation, the slave mode leading to implementation of the method for processing transaction data under the exclusive control of the card reader; of entry, by the user on the virtual keypad, of the piece of personal identification data; and receiving, from the card reader, the piece of personal identification data.

Abstract: In exemplary embodiments, a reader device is powered on only when a card is inserted in the reader device, thereby reducing the amount of time the reader device is powered and consequently reducing the amount of power consumption by the reader device. In some embodiments, inserting the card causes power-on of the reader device, while in other embodiments, insertion of the card plus other criteria are required to power on the reader device (e.g., having the reader device connected to the host device, or operating a manual switch while the card is inserted in the reader device).

The peripheral device includes at least one first portion of a contactless communication of the electronic payment terminal and at least one connector that cooperates, when the peripheral device is coupled to the electronic payment terminal, with at least one complementary connector on the electronic payment terminal. The connectors form a wireline communication between the first portion of the contactless communication of the peripheral device and the electronic payment terminal.

The method includes: a first non-secured pairing phase for pairing the transactional terminal with the communications terminal, delivering at least one pairing parameter for pairing with the communications terminal, by using a first radio-type bidirectional wireless communications channel; a second phase of secured pairing of the transactional terminal with the communications terminal, the second pairing phase implementing a second unidirectional communications channel used by the transactional terminal to transmit a piece of securing data from the first communications channel to the communications terminal, as a function of the at least one parameter for pairing with the communications terminal.

Abstract: A method for pairing a first terminal, called an initiator terminal seeking to transmit and receive data, with a second terminal, called an acceptor terminal. Such a method includes: placing an external surface connector of the initiator terminal on a complementary external surface connector of the acceptor terminal delivering a piece of data to the initiator terminal about the presence of the acceptor terminal; determining, by the initiator terminal, of a parameter of connection; and pairing the initiator terminal with the acceptor terminal according to a mode of pairing depending on the determined parameter of connection.

Abstract: User credit card data or smart chip data or Near Field Communication data is easily transferred from a card reader to a host device via a matrix bar code such as a Quick Response (QR) code. Data transfer is performed by converting the card data into matrix bar code and allowing the host device to take an image and process the image to obtain the card data. Card reader will convert magnetic signal/smart chip/NFC data into machine readable form and then convert it into matrix bar code to be consumed by a device that is capable of capturing the matrix bar code. The card reader has the ability to encrypt the data before converting it into a matrix bar code.
