I have a credit union, so for me easy access to ATMs means going to the nearest 7eleven.
You may understand the unease I had at first, but really when compared to a Chase ATM, it was about the same.
So for my personal security, I always check for card skimmers by gripping and shaking the scanner. Then, I use one hand with two fingers, or two hands to enter the PIN for one of two reasons: speed; reducing the amount of time at an ATM, or for blocking visual access to the keys I press. I always look around for any "security cameras" around the ATM.
I try to only visit the same ATM, so I can see what changes in the hardware.
Then when I'm done, I randomly press keys to protect myself against heat signature attacks.
Finally, I wait until the terminal is ready to accept a new transaction. #1 I always ask for no receipt. And because of the inconsistent manner ATMs function, I can't trust that nothing will come out, so I wait.
#2 some ATMs actually wait for input to close out a session "Would you like to perform another transaction?"
So I don't trust ATMs very much, except that they'll give you the correct amount of money.
On an aside, I'm using firefox on android, and it seems to lag terribly. And when I swipe the top stories, the entire page swipes to nothing. smh
