Among the specific requirements of POS, useful for facilitating payment by the blind and visually impaired, the following have been identified in particular:
• the activation of payment through a special dedicated function;
• the management of messages addressed to the customer (e.g. choice of circuit, confirmation of the amount entered by the merchant, entering the PIN code) through a voice guide;
• the management of entering the PIN code through sound supports;
• the specific positioning of the keyboard;
• the appropriate screen contrast.
Compliance with the indicated requirements is mandatory for those who intend to approve their touch POS (so-called touch-screen) solutions within the circuits managed by BANCOMAT S.p.A.
