Just noticed Something practical in the SIGN border Control section that the whitepaper completely Ignores
the Whitepaper describes border control using Sign Protocol's on-chain identity system — "Scanning passports" via NFC chip reading with ICAO 9303 compatiblity.
the system verifies security status by reading the ePassport chip against on-chain encrypted records. instant verification. no data sharing between countries. privacy-preserving.
the part that surprises me:
ICAO 9303 ePassport chips have a real-world failure rate. chips get damaged from physical wear, water exposure, bending, proximity to strong magnetic fields, or manufacturing defects. border control officers encounter unreadable chips regularly. in traditional border control, an unreadable chip means fallback to visual inspection of the physical document — the passport is still valid, the chip failure doesn't invalidate the document.
in SIGN's architecture, if the identity verification depends on reading the NFC chip against on-chain records — what is the fallback when the chip fails? the whitepaper describes the system as requiring chip reading for identity verification. it doesnt describe a fallback process for chip failure.
still figuring out iF
a citizen with a damaged ePassport chip attempting to cross a border under SIGN's system faces an undefined scenario. the on-chain verification cannot complete without the chip data. does the border officer fall back to traditonal inspection? does the citizen need to get a new passport? is there a temporary override mechanism?
the whitepaper presents ePassport integration as an efficiency and privacy improvement for border control. it doesnt acknowledge that ePassport chip failure is a routine operational event that every border system must handle.
