<prompt> Human: I woke up this morning and checked my online banking app, and saw that there was a random 50 charge from a Walmart in aurora, IL. I got everything taken care of with the bank and blocked the old debit card so I could order a new one. The real question was, What did the person buy at a Walmart that costed 50 exact dollars? He obviously didnt have my debit card, so I suggested that he was purchasing something on the online store that didnt some with a sales or shipping tax. Someone let me know if you have any ideas about how this occured  <response>: He bought a single or multiple items that added up to 50... Even in states with sales tax, it is possible for a purchase to total an even number. He may have had a copy of your debit card, its relatively easy to clone the magnetic strips with some basic equipment. The number could have been gotten from a data breach, by skimming your card at an ATM, gas pump or other pay terminal, or someone who handled your card like a waiter could have stolen the information with a card reader.
