What's the safest approach if you come across one of these in the wild? If you had already put your card in, you wouldn't want to just leave the device around waiting for the thief to pick it up. But you probably also don't want to be the person pocketing the memory chip with other people's debit card info.
I suppose taking a cell phone video describing your thought process and recording your interactions with the device is a good precaution to take whatever you end up doing with it.
I actually found a similar one today on the ATM outside my bank. Went in and notified the manager - he immediately disabled the ATM and posted someone outside to stop people from using it until his security team and the police could arrive.
