4 TRENDY ALTERNATIVES TO CREDIT CARD SLEEVES
If you’re the type of person who carries cards instead of cash, you might want to look into buying a credit card sleeve. Credit card sleeves are a minimalist alternative to leather wallets that are becoming more attractive to people looking to minimize how much cash they carry. Credit card sleeves can also be used as additional RFID protection for individuals looking to protect the credit cards in their wallet.

How do I protect my credit card in my wallet?
Do RFID blocking sleeves really work?
RFID blocking sleeves and wallets work by protecting your credit card details from scammers. Your credit cards are likely already embedded with an RFID chip which allows you to make contactless payments.

Unfortunately, your credit card information can potentially be compromised using devices called RFID scanners. RFID scanners can pick up information such as credit card numbers, CVV codes, and expiration dates. Once the scammer has your credit card information, they might be able to make a purchase using your credit card information.

RFID blocking sleeves have a thin layer of metal or carbon fiber that prevents RFID scanners from reading your credit card’s RFID chips. Not all credit card sleeves have RFID protection, so choose carefully if having RFID protection is important to you.

If you’ve ever ventured into the world of paper Magic, you’ve probably bought some card sleeves before. And if you’ve bought a couple different brands or types of sleeves, then you’ve definitely noticed that there can be a pretty big difference in quality. If you’ve never bought card sleeves before or have only ever bought the same ones, well, now you know.
