Contactless payment terminal

A method of operating a payment terminal,

• the payment terminal comprising:
• a contactless payment transceiver;
• a display;
• and user input apparatus comprising a select input, an increase input and a decrease input, wherein the method comprises:
• displaying an initial numerical value;
• responding to detecting user operation of the increase input by incrementing the numerical value displayed on the display;
• responding to detecting user operation of the decrease input by decrementing the numerical value displayed on the display;
• responding to detection of user operation of the select input by setting a transaction amount that corresponds to the numerical value displayed on the display at the time of detection of user operation of the select input;
• and
• using the contactless payment transceiver to initiate execution of a transaction for the transaction amount with a contactless payment token.

A payment terminal comprising:

• a contactless payment transceiver;
• a display;
• and
• user input apparatus comprising a select input, an increase input and a decrease input, wherein the payment terminal is configured to:
• display an initial numerical value;
• respond to detecting user operation of the increase input by incrementing the numerical value displayed on the display;
• respond to detecting user operation of the decrease input by decrementing the numerical value displayed on the display;
• respond to detection of user operation of the select input by setting a transaction amount that corresponds to the numerical value displayed on the display at the time of detection of user operation of the select input;
• and
• use the contactless payment transceiver to initiate execution of a transaction for the transaction amount with a contactless payment token,
• wherein the user input apparatus comprises an input device having an aspect that can be moved by a user to positions either side of a zero position and is mechanically biased to the zero position such that the aspect of the input device returns to the zero position in the absence of applied force, and wherein the payment terminal is configured to control the rate of incrementing and decrementing the numerical value depending on a detected amount of deflection of the aspect of the input device from the zero position.
