I am glad to see that the media does warn people that this happens. Ottawa still has a fair number of “shadey” folks who are trying to steal money from you, any way they can figure out.
I have seen examples of how these kind of scams work, I guess the only advise I can give is watch what the employee does with your card, don’t just turn your back and assume they are doing the right thing. You are giving this person access to your bank account, so treat the transaction with a certain amount of due diligence.
A gas station locally used to have employees who would swipe your card twice, once to clone the card and once to put the actual transaction through and then had a “pin snatcher” on the line as well, so the cloned card could actually be used as well. This is why it is useful to have “working” bank accounts where your balance does not get too large, and thus if someone does “snarf” your card, they can’t get that much money (hopefully you can recover the stolen funds, but it might take a while too).
Fraud is out there, be diligent folks.
