Wrap the license in lead foil.
If I’m not mistaken, this is the equivalent of the chip in the “passport card” - which is a card very much like a drivers licence (same design and dimensions as a DL).
The passport card can take the place of a book passport, for (land) borders around the continental US, such as the border with Mexico, Canada or I believe ship crossings to Gulf coast area vacation destinations. I don’t think those rules are in place yet - but they roll out some time this year? (you thought the digital tv’s created confusion...) You’ll still need a passport book if you’re flying into Mexico or Canada - but at the border a passport card will be acceptable. You’ll actually need either the card or an actual passport, to get back into the States once the rules come online - so these are becoming more important.
The passport card has an RFID chip with an identifying number broadcast. Allegedly there’s no biometric information on the chip - that’s evidently held in a database, and the identifying number is the database key.
Those passport cards come with a tiny sleeve, and the instructions state the card should be kept in the sleeve when not being presented.
There are a number of shield options, some available from better travel supply sites, and directly from vendors.
The chip in the passport card (the one similar to a DL) is not the same chip which is in the passport book - the chip in the passport book does have biometric information. However - allegedly - the passport book itself is shielded when closed, and the biometric info is supposed to be encrypted pretty strongly.
I think one state might already have an RFID license equivalent to the passport card - Washington maybe?
The thinking seems to be, one of the enhanced DL’s can take the place of a passport under the new rules for land borders, so people who live near a border might want one. You have to actually request one, for now anyway.
‘Course they said you couldn’t get a ticket for not wearing your seat belt, when that law started out.
Didn’t take long for that so-called protection to fall by the wayside...
Anyway, I think that’s all pretty accurate.
