Offline presentation QR and NFC. i thing about this with regard to embedded systems this semester. the professor explained the importance of offline capability in critical infrastructure. if something only works when it is connected to the internet, it is not infrastructure it is a service that requires that connection.

that lecture stayed with me longer than most. then i read the offline presentation section in Sign Protocol's identity doc.

Sign Protocol supports off line credential presentation using QR codes and NFC. a citizen with a national ID attestation in SignPass wants to present his credential at a check point without access to the internet. the verifier device checks the signature against the cached public key. there is no network call. the credential either works or it doesn’t. this works in a village with no data signal as well as in a city with a 5G signal.

most blockchain based identity solutions need network connectivity for verification. this right away excludes them from the countries where the infrastructure matters the most.

do you think the offline verification capability is the one that actually decides the identity protocol for the government? comment me i seen and reply.
