Is my RFID paranoia warranted?
A year ago I received my new passport and passport card(which came in a metal lined sleeve). Today I received a new credit card with an RFID chip for quick checkouts.
I'm worried someone can skim my credit card information from my wallet at a distance and when I'm travelling skim my personal information off my passport.
Is my paranoia warranted? Should I be wrapping my passport and credit cards in aluminum foil? Should I go searching for some RFID signal blocking sleeves?
