Have you ever wondered: Why is there braille on drive-thru ATMs?

SIOUX FALLS, S.D. - Lerae Olesen said she usually goes inside the bank or has a sighted, trusted friend help her withdraw money. She rarely uses the ATM by herself because it's just easier not to.

"The reason for the braille is to give blind people who use braille total and complete access to their banking information to be able to transact money independently," Olesen said.

It's a federal regulation that all ATMs have braille because of the Americans with Disabilities Act. There must be braille instructions on the machine to let the user know where the headphone jack is to complete the transaction. All ATMs had to be up to code by 2010.

"They may not be driving, but somebody blind could be riding in the car," Teresa Ulven said. She is the network, finance and sales supervisor at First National Bank in Sioux Falls. "They don't want to have to give their card and PIN number out to somebody. So they want to allow them to use the ATM as well."

People are not encouraged to give out their PIN because if someone has that and a credit card number, then they can use a card without physically having it.

"You're open to fraud. You're open to people's disputes and it's on the cardholder then. If they share their pin, then you can't dispute it," Ulven said.

Even though Olesen doesn't use ATMs by herself often, she's glad they are this accessible.

"It gives everyone, including yourself, a sense of well-being to be able to do the things that other people can do and to be able to have that privacy," she said.

Because at the end of the day, many of us want the same thing.

"To function as 'normally' as possible," she said.

There are many spots in day-to-day life where there is braille that we don't even notice. Olesen said there's braille on elevators so she knows what floor she is on if she's at the doctor's office for example.
