QT850 Payment terminal strives to strike a balance between accessibility for the visually impaired and smart features for able-bodied people. Hence the retention of a tactile Keypad for private and secure entry of a user's PIN (Personal Identification Number).

This standardised keypad layout is familiar to the visually impaired, with embossing on the '5' as an orientation key, and symbols embossed on the Enter, Clear and Cancel keys. All customers will have 3 opportunities to enter a correct PIN. A fourth error will result in a cancelled transaction and depending on the card issuer, the account may be locked.

Common and unique sounds are integrated into the payment experience. Sounds are unique for keypad presses, errors and successes.

Prompts and instructions on the Display are high contrast (white on black) to aid those with low vision.

Card / Device acceptance is simplified by use of a large contactless tap zone located intuitively on the full face of the product (not a small zone on the side, back, or top). The smart card slot has a large funnel design with slot illumination for added usability.

Merchant obligation

It is common practice and expected that a merchant should assist a person with an impairment. This may include card presentation, account selection, receipt giving. Under no circumstances should a merchant request that a PIN number be divulged for entering into the terminal.

If customers are uncomfortable with the accessibility functions of the terminal, the best approach is to suggest the customer use contactless. In Australia, Contactless cards usually have a floor limit of $99 without requiring a PIN. When using a smartphone and card saved in an eWallet (ie. Apple Pay, Google Pay or Samsung Pay), no PIN is usually required.
