This could be the key to my hotel room or to my #nostr #safebox zap wallet.
Or both!

or wallet.
Or This the to room to be could my my key hotel both!
#safebox zap #nostr
I want to use NFC cards for door locks where I generate the private keys myself and have control over the fuctionality of the key locks. That would be cool to have House/Room Keys over NOSTR
it can’t
yet
*could
hotel keys and similar use MIFARE, not NTAG
I'm looking into that format, too.
Prepare to sign an NDA for any serious documentation
Well then, I won’t use it.
And you probably don't need to, anyway
I also will try to stay away from ISO pay-to-read standards. There’s a big shitstorm brewing on this front with mobile driver’s licenses.
in smart cards, everything is either pay-to-read or sign an NDA to read
I know and screw that.
Unfortunately anything that is not is also trash 😬
There is pressure in the industry to open up these standards. The goal
is to show compelling alternatives that need to be more secure. The market will need to exert pressure to open up these standards or build
better ones.
"There is pressure in the industry to open up these standards."
unfortunately no, there is not, as someone that wants exactly this
I have encrypted data on the card. I’m not worried about that. I just need to know it’s being read from an authorized reader/app
Wait until i tell yall about SAE-ISO protocols. To use some of the more in depth protocols to talk with ECUs you're only options _through official SAE channels_ is to become a "partner" register for classes during a select time, and purchase class materials such as the protocol documentation, take the class (if there even is an online class) then, possibly you may know how to interact with a particular protocol without reverse engineering it. Hint, if you're smart enough, it's far cheaper to packet sniff and attempt to reconstruct. The issue is it's not repeatable across mfgs and vehicles. You also need to have a business TIN registered and I think becoming a partner required a donation of like $5k.
Finally, it's often against copyright protection to use this knowledge on a real vehicle, such as flashing firmware or entering boot-mode.
The smart card industry is mostly a bunch of banking and ID card companies.
The protocols are actually not shit (we don’t talk about T=0)
Would be cool to have the ability to decide to have NFC tap for payment/pass entrance/etc either on the phone (not bound to a centralized system, but independent, self custody) or card, or both user chooses. Can. Create copy on cards if ones wishes.
...or neither
