From reader Matt S., on a phenomenon people have been musing about for years:
No, if you think about it, it’s fairly easy to understand that one..
They have to have the braille on walk up ATM and it’s just easier to have one set of buttons on a given ATM model that can be installed anywhere, than to manufacture two different sets of controls for any one model, one for walk up installations and one for drive through installations.
Once you have to have braille on some ATMs, basic economics says that it will be more cost efficient to have it on all ATMs.
It’s part of a lively reader discussion of accessibility rules.
