<prompt> Human: Hello PF! My wife and I share the same Discover card account. The Discover it Card that gives cash back and doubles it at the end of the year. Its been a great card thats treated us well. With two exceptions.A few months ago we noticed a couple Lyft charges for 150 or so that we certainly didnt charge. Called Discover, they cancelled the account, rushed us new cards in under two days and transferred our new rewards to our new card. No big deal. I updated all our auto pays and online passwords etc..Just today I saw a Nordstrom charge for just shy of 2800. Again, not our charge. Same conversation with Discover. Well have new cards tomorrow or the next day.My question is this: Why is this happening with only our Discover Card? And why twice so close together? We shop at the same locations close to where we live and we utilize other cards there as well... weve had no issues with other cards. Most of our recurring payments are processed on this Discover. So, what can I do better to ensure my safety in the future?Thanks a bunch!  <response>: A big one is if you use that card online then your computer might have malware were someone is collecting it If not try to remember where you shop with the card and a store you frequent might be compromised
