could somebody ELI5 the threat vector here? I'm not skeptical, I just don't know what to imagine.
backdoor implies somebody can "get in" to my rfid, but rfid's spend most of their time "off the grid". So when my rfid powers up, does the "host" who powered it up also need to be insecure or on an insecure/compromised net?
then... what capabilities would suddenly become possible; unlocking the door is already unlocked, my credit card is already all ready to spend...
or does it simply allow people passing me on the sidewalk to make a copy of my card?
