"For instance, a blind person can expect the modules to be in the same place on all ATMs, regardless of the model or whether it’s a drive-up or through-the-wall," he said.
"Barker also pointed out that disabilities come in many shapes and sizes, so it is important to get feedback from the people you are actually trying to serve."
