Many new forms of official ID contain an RFID chip. I understand that said chips can be read (harvested) by someone nearby who has the proper scanner / reader on his (her) person. Those “special envelopes” are supposed to prevent walk by scanning. I ALWAYS used protective sleeves on any “chipped” item. I bought extra sleeves on Amazon for my chipped credit cards.
