Accessibility at Checkouts.
DMV high countertops use card and PIN with no tactile (physical PIN), USPS high counters no POS access from a wheelchair, a small business, using fixed countertop mounting in addition to say a clover using no tactile PIN etc.
The purpose of accessible POS mounting is to give the same ease of use and privacy including PIN entry privacy for all people and not limited to the standing.
The POS card and PIN reader need to be properly mounted for wheelchair users, little people and even very tall people with bad backs who too have problems with poorly mounted POS devices.
At Taylor POS, we not only provide the best POS mounting for businesses, but we are also available to educate across the board, meaning, businesses, IT, C-suites, Mom and POP shops, Governments, Military, and others.
Accessible POS
ADA Title III requires access to goods and services provided by privately owned public government and military accommodations. All businesses with a POS card and/or PIN reader at checkout must meet the specified accessibility requirements.
In addition to the current active enforceable California code requirements, the U.S. Access-Board is publishing an NPRM for POS Checkouts with new assistive-accessible requirements (2023) and then onto the Final rule to be adopted by the ADA as enforceable.

CBC 1.1.7.3 (Conflicts).
When/if the requirements of this code conflict with the requirements of any other part of the California Building Standards Code, Title 24, the most restrictive requirements shall prevail.
Regarding ADA reach and range requirements, note that it is the assistive technology within the reach and range that matters and that is where the ADA 309 operable parts and 309.4 operation requirements that address ADA 302.8 and 508 (ICT) 302.2. aka: ADA Visual Accommodation.
For use with limited reach and strength and ADA Visual Accommodation.
