The vast majority of PIN pads on point-of-sale terminals have a tactile feature that includes a raised dot on the
middle ‘5’ button. This layout will be familiar to most people with vision impairments, and should therefore be
easier to use. Also, the primary 'function' keys are colour coded for ease of visibility. Usually, the 'cancel'
button is red, the 'clear/cancel' button is yellow, and the 'Enter/OK' button is green.
Many PIN pads are designed to be picked up from their holders, to make it easier and more secure to enter a PIN.
There are also PIN pads which have been built into the shop counter, and in restaurants and bars the PIN pads are
likely to be (or will soon become) wireless so that your customer can pay whilst sitting at the table. Whatever
the case may be, your staff should always be able to help the customer through the process and answer any queries.
However you or your staff should never ask the customers to disclose their PIN, it must remain confidential/secret
to the customer at all times.
Research with blind/visually impaired cardholders in February 2013 showed that the vast majority of those
interviewed were happy to use a PIN, having tried it and found it easier and quicker than signing.
