If someone did that, they are an idiot. The card transactions are linked to your bank account, when people call their banks to alert them about suspicious transactions, Sumup will be told by the banks when requesting the money back. Bank will have all the criminal's details from the bank account so they will be caught and prosecuted. Also, in the 2-3 days it takes for the money, it's likely that Sumup would be alerted by the bank beforehand and not release the funds in the first place.
Just ignore @MisterNippy who seems to want to tell everyone how bad these are in the case you get scammed by them in a random act by a fraudster on a busy train. But this deal has been posted to try and help local businesses or charities or individuals to help cut costs. As it is an excellent product of its kind. Next you will be commenting on a deal for a knife set, stating that anyone over 18 can buy them and go on a stabbing spree and how bad the knife product is. As previously mentioned further up the thread you would need to have to have direct contact with the machine and the card, which I doubt you can do through the layer of clothing, then the wallet etc. If you don't like the product then vote cold don't take every opportunity to enhance a minimal opinionated flaw.
