You might not know it, but there’s a good chance your credit card has a chip in it that sends out a signal. That’s how you can use it without swiping it at merchants, when you just wave it in from of the card reader.
It’s very convenient, but the problem is thieves are now using equipment to steal that signal, which contains very important personal information about you.
To prevent this from happening, you should invest in rfid blocking wallets , which block the signals and keep trolling thieves from getting your information.
