That assumes permanent RFIDs on stuff like that, very unlikely,
if only because they can then be a problem at the checkout.

You can obviously avoid that if you're mindlessly
paranoid by not taking your cards into the store.

And they can keep track of what is purchased using particular
credit cards etc without bothering with RFID right now anyway.

I couldnt care less if they keep track of what I have bought.

See above on permanent RFIDs on the stuff you wear.

And if you dont like that, its completely trivial to zap those RFIDs anyway.

Fat lot of use that is to anyone.

Completely off with the fairys, as usual.

If you dont like that, pay cash.

And they dont bother with the current
system which doesnt use RFID anyway.

Its just another of your silly little luddite fantasys.
