If you’d like to protect your cards with RFID chips – like drivers licenses in some states, credit cards, and passports – from being scanned without your knowledge, you have several wallets to choose from. However, you can now protect individual cards without having to replace your wallet. The practical_pats store at eBay offers Tyvek envelopes with RFID shielding inside. They come in two sizes; one size fits a single passport, the other is perfect for a credit card. A single passport envelope is $5.99; two are $9.95. Credit card envelopes are $6.99 for 5, $10.99 for 10, or $15.99 for 20 envelopes. Shipping is free. Go to the store linked above and search for “tyvek rfid” to see the current options.
