@AdventureElephants A carried ID can be checked by anyone with eyes; pretty handy when you don’t have a working RFID reader with a good connection to a trusted database. Also, while it’s relatively easy to make a phone ID, it’s even simpler to tamper with a database; it just takes a different skillset. Thing is, fake or real, a physical ID cannot be altered remotely. That sort of immutability is a security feature.
The most foolproof way to prove identity is a hybrid system of a physical object that only one individual could possibly obtain that is corroborated by a database to prove that it isn’t a forgery. For instance, if I have a tamper-proof photo ID with a picture that looks like me and lists the correct height, weight, and eye color, and checking the number on that license pulls up a database entry with the same information, that’s pretty solid proof as it would take a lot more effort to fool that sort of system than it would to just do a little Photoshop work and hack the database.
Conversely, if there is a mismatch there, that’s not proof-positive that I am not me, only that one of the two is wrong. Since I served in the US military, my fingerprints are on file already, and it’s unlikely that both the DMV’s computer system and the FBI’s paper files would get altered. If push came to shove and the legitimacy of my license is questioned, I have ways of proving my identity through “web of trust” means that don’t involve implanting an RFID in my body.
“If you thought your movements were being tracked more with a chip than with your cellphone, cameras everywhere, and satellites… Couldn’t you just remove the chip?”
That’s precisely why I wouldn’t want an implanted chip. Satellites have limits, cameras can be dealt with, and smartphones can be ditched. Considering that I’m a little squeamish about blood though, removing an implanted chip really doesn’t sound feasible to me. If I were in a position where I was worried about being tracked and did the whole cloak-and-dagger, off-grid paranoia thing, I could drop off the radar despite all the cameras and such. However, it’d be a lot easier if doing so didn’t involve DIY surgery. Given how I know some of the ways RFIDs can be abused (not always by the government; black-hat hackers are very clever and creative), I see implanted chips causing a few problems while offering no real benefit over what we have now.
