<prompt> Human: Im not sure if Im in the right place, but anyway, Id seen it on the news with ATMs, but today I went through the drive-thru at McDonalds, and in an pretty smooth move the girl ran my card through the machine, then right through a little black box in her hand. I asked her why she had to run it twice, and she said sometimes it doesnt work the first time. When I asked specifically about the little box in her hand, she then said she only swiped it once. I talked to the manager and asked her if they had handheld card swipers for some reason, and she said no. Then I just let her know that the first window person ran my card through a little black box and put it under the register she was working. Anyway, I have a pretty decent suspicion it was some kind of skimmer. Just to be safe, I went to the bank and asked for my account to be frozen for now and a new card, which I feel like is the right thing to do. But what I dont know is what information those things are capable of getting. How long should I leave my account frozen? And are there other things that I should address? Its not a huge deal to me, its one card, its not that hard to switch it out, people are shitty, itll happen. But I just want to make sure that freezing my account and getting a new card is enough to prevent any damage. Thank you in advance for any advice.  <response>: Yeah getting a new card with a new number will solve this. Id definitely contact the police though, for the sake of others. It amazes me what people will do.
