What do the symbols mean in the Direct Express app's ATM finder?

There is a filter if you scroll down on the ATM Finder page, which allows you to search for any of the 3 options, plus Wheelchair Accessible locations or Drive Throughs!

The three colors mean:

• Red: regular ATM; You may be charged a surcharge fee by the owner of the ATM and transaction fees may apply.
• Blue: surcharge-free ATM; You will not be charged a surcharge fee by the owner of the ATM but transaction fees may apply.
• Green: cash-back location; These are stores that can give you cash back when you make a debit purchase with your Direct Express card.
