ACCESSIBILITY
The accessibility function allows visually impaired customers to use the payment device. It supports Assistant PIN Entry,
Accessible PIN Entry and training.
Accessible PIN Entry
Description
Accessible Pin entry allows blind people to enter PIN themselves without
having to disclosing the PIN to the merchant.
If the accessibility option is enabled in the configuration, the user can
double tap anywhere on the card prompt screen or press a tactile button
(the scanner key) to enter Accessible PIN Entry mode. In this mode the
PIN entry screen is blank.
Once Accessible Entry Mode is activated, the Total amount is vocalized
and the instruction on how to present a card is vocalized (“Please
present your card”).
The Accessible PIN Entry keypad is a standard 12pad format with 10
digits, an OK and a Cancel button. The customer can navigate through
the keypad by dragging their finger across the screen. An audio feedback
will be played each time the customer moves to a different key in the
keypad.
The customer can double tap anywhere on the terminal screen or press a
tactile button to confirm that key they last navigated to.
Once the PIN entry is done, the customer can navigate to the OK button
(on the bottom right corner) and double tap anywhere on the screen or
press the tactile button to confirm.
To cancel at any time during the PIN Entry, the customer can navigate to
the Cancel button (on the bottom left corner) and double tap anywhere
on the display or press the tactile button to exit the PIN Entry screen.
The customer will also receive audio feedback to report if PIN entry was
correct or incorrect.
After two unsuccessful PIN entries in Accessibility mode, the customer
will be guided through a short training exercise to explore, navigate, and
practice digit entry (double tap/press the tactile button). In this mode,
the terminal identifies keys using audio as they are selected. The
customer selects and double taps/presses the tactile button or “Cancel”
at the bottom left corner to exit training. On exiting training, the on-
going transaction is cancelled, and a new transaction must be started to
allow card and PIN entry.
