Seven “Wonders” of the ATM World

After years of using ATMs I’ve stumbled across several unsolved mysteries I never quite understood. Some are just funny curiosities others I really always wanted to know the answer to. I’ve talked to others and realized I’m not alone in just not along in being confused by these enigmas. I decided to research the answers to each of these questions, so I present to you my seven wonders of the ATM world. With answers!

The Wonders

1. Why do ATMs allow you to enter the amount you wish to withdraw in penny increments? If I type in I want $53.28 it's not like it's going to shoot a quarter and three pennies out of the bill changer. Pretty much all ATMs only give out cash in $10 or $20 increments so I won't even get the three ones! Why not just type in the dollar amount? It sure would be a lot simpler.

2. Why do-drive up ATMs have Braille? This is a common wise-crack many people have made. The rationale is blind people shouldn't be driving, and there's warning on most drive up ATMs telling you not to walk up and use them, so why have Braille.

3. What does the Braille say? This isn't one I've heard any one else ask, but I think the better question than why do the drive up ATMs have Braille is what could it possibly say next to those buttons? The function of the buttons change with every screen. In recent years they added headphone jacks that probably solve this problem, but for years they didn't. So what do the buttons say?

4. What's with the $2.50 or more fee you have to pay when using an ATM from another bank? I can almost understand the $1.50 fee the foreign banks ATM charges you for using their machine, but why does your own bank charge you another dollar. They don't charge you when you use that same card to pay for something at a store so why is it any different when you use an ATM. The $1.50 seems high too, especially when you only take out $20. A merchant is only charged around 30 cents on average to make that same $20 purchase on your check card.

5. Is the "Fast Cash" option really any quicker? I don't think so. I rather skip that screen all together and just go to the 10 key. It takes me longer to search for the dollar amount on the Fast Cash screen and try to figure out which button it almost lines up to than to just type it in. Also the inputs are usually in $20 increments so I have to go to the 10 key anyways to get my $50 out of the machine.

6. Why are PINs 4 digits? It seems backwards that my email provide feels it's necessary to secure my account with a password that is at least 8 characters, alpha numeric, has at least one upper and lower case letter and at least one number, yet my bank it feels four numeric characters will suffice. It's 1 in 10,000 pretty good odds of guessing someone's pin? If you consider that most people use some sort of date as their pin in MMDD format, you're down to 1 in 365 odds.

7. What do you do if the ATM give you the wrong amount? There's usually a number to call on the ATM, but how do you go about proving you got the wrong amount.

The Answers

I researched these answer to the best of my ability, however on some of them the answer just isn't there to be found so I had to go on speculation.

1. It appears to be for consistency sake. When you make a deposit you can enter a decimal amount, so they provide that option for withdrawals as well to keep the input format consistent.

2. The primary reason is legal compliance. The Americans with Disabilities Act requires all ATMs to be accessible by the blind. You may think this is one of those stupid laws in the case of drive-up ATMs, but there actually are some good scenarios where the Braille would be needed. The main one that comes to mind is for when a blind customer is in a cab and needs to get cash.  I know I sure don’t want to give my card and PIN to a random cab driver!

3. All ATMs are designed differently but on most the Braille options are just the numeric values for the 10 key and alpha values for the option buttons. For the years blind customers had to memorize the keystroke sequence. Fortunately newer ATMs have headphone jacks which provide audio instructions.

4. In short because they can. Most people are surprised to learn that the primary source of income for many banks isn't the interest they make from loans or from investment commissions, but from charging fees. Overdraft fees, refinancing fees and yes ATM fees. It has become a significant source of income for banks over the past decade and rates continue to rise. Of course customer frustration with this also continues to rise and many customers have begun switching banks. As a result some banks have stopped charging fees and certain online only banks have gone as far as reimbursing their customers for the fees the other bank charges when using a foreign ATM.

5. It's not faster for me, but then again I'm pretty quick with 10-key and usually want $50 which is not on the menu. However, not everyone is 10-key proficient and are many are ok with taking a $20 increment. It has an added benefit of encouraging you to get a $20 increment which allows the bank to more efficiently pack the ATM with mostly $20 bills.

6. Old standards are hard to change. Even if your bank decided to install a full keyboard and allow alpha-numeric, you're going to have a real problem when you go to foreign ATM that still only accepts 4 digit numeric and try to get your money out. What incentive does any bank have to be the first to offer this? There's also some interesting standards around how ATM pins work that would have to be changed. We'll talk more about this in a later post.

7. In theory they should be able to count the cash remaining in the machine and find the difference. Even if not, if you're a good customer and they don't have any other reason to suspect fraud from you, they'll usually just give you the benefit of the doubt to keep you as a customer. If all else fails a call to your local TV station should get the problem solved for you.
