Nostr Web Client

I am always intrigued by the #nostr #safebox ads that ChatGPT generates. I can’t but help think about what the use story might be for this person, wearing the nfc tag like a dog tag.

In this case, it might be someone ready to evacuate on a moment’s notice (ballistic missiles, anyone). They might not be able to take their phone with them, or connect to the network. But they might know that there are emergency shelters with satellite uplink, and even if they lost their phone, they could borrow one to pay, or better yet use the nfc card directly for payment and proof.

This is #nostr #safebox

i don't know anything about safebox, but can the nfc be unlocked by someone else? wondering if there's an incentive for theft.

There is that risk, the same as any other card you have in your wallet. Basic NFC is dirt-cheap, about $0.25 per tag. There are more secure PIN-protected tags but they are much more expensive. If your card is stolen, the attacker would have to know what to do with, if they even know it’s a NFC tag. Plus you can rotate the secret immediately rendering the stolen card useless.

It’s all about tradeoffs - I am focusing on 100% accessibility and 100% inclusion first, then dialing in the security controls as appropriate.
