Protect tappable cards and personal ID from wireless RFID pickpocketing

When I first got my Nexus card for fast entry to the U.S., I really didn’t understand the importance of keeping it in its protective sleeve. It turns out the card uses RFID (Radio Frequency Identification) chip technology, which over the past five years has also become embedded in passports, health cards, drivers licenses, grocery store dongles, gas station dongles, debit cards and credit cards in many countries to help us get serviced faster by tapping/waving them when we are buying a coffee, gas or crossing a border.
