Accessible PIN Entry
Accessible Pin entry allows blind people to enter PIN themselves without
having to disclosing the PIN to the merchant.
If Accessible function is enabled, a special chime will be played periodically
to inform the user that he or she can invoke the Accessible function. The
user can perform a double-tap anywhere on the device screen or press a
tactile button (the scanner key) to enter Accessible PIN Entry mode. Once
Accessible Entry Mode is activated, the Total amount is vocalized and the
instruction on how to present card is vocalized (“Please present your card”).
Multi-Touch: To give the user a better user experience, the Terminal will
reject the palm touch or multi-touch during Accessible PIN entry.
The Accessible PIN Entry keypad type is a 12pad. The user can navigate
through the keypad. The audio feedback will be played once the user
switches to a different key in the keypad. The user can double tap anywhere
on the Terminal screen or press a tactile button to confirm that key he or she
last navigated to. Once the PIN entry is done, the user can navigate to the OK
button (on the right bottom corner) and double tap anywhere on the screen
or press the tactile button to confirm. For doing cancellation anytime during
the PIN Entry, the customer can navigate to the Cancel button (on the left
bottom 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 if the PIN entered is correct or not.
After two successive unsuccessful PIN tries in Accessibility mode, the user
will be taken to the short training to explore, navigate, and practice digit
entry (double tap/press the tactile button). The training keypad would
behave same as accessibility except that the key digits are spoken out. The
user selects and double tap/press the tactile button on “Cancel” at the
bottom left corner to exit training. On exiting training, the on-going
transaction would be cancelled, and a new transaction has to be started to
do the card and PIN entry.
Once the Accessible function feature is enabled, the terminal works in this
mode for all subsequent transactions until disabled.
