A few months ago, I saw the Jonas Brothers kick off their world tour with back-to-back shows at Yankee Stadium. I sang, danced, screamed, sweated, cried, traded bracelets, got rained on and even did karaoke with Jimmy Fallon (???).

I also spent a LOT of money. I'd bought the tickets back in April, so the seats were paid off, but between Yankee Stadium's $40 cocktails, the $70 I dropped on limited-edition merch and the $30 worth of chicken tenders I scarfed down after the show, I felt like I was constantly pulling my card out of my wallet to pay for one thing or another. And despite my JoBros bliss, I started worrying about whether it was truly safe to do that in a crowd of thousands.

I know there’s an entire industry around RFID-blocking wallets — but would they help in this situation?

Do I actually need to use an RFID blocker to protect my money?
