Hello all,

This EFF article 
<https://www.eff.org/deeplinks/2021/06/decoding-californias-new-digital-vaccine-records-and-potential-dangers> 
explains the California digital vaccination card in terms a layman can 
understand.

Singapore's HealthPass is based on the same Verifiable Credentials and 
FHIR data, but personal data is not in the QR and the VC document itself 
is anchored to a blockchain.  It seems to me that Singapore's HealthCert 
is lightweight, tamperproof and much better than California's system.

The Vaccine Credential Initiative (promoting Common Pass) and IATA 
(promoting Travel Pass) have made it seem that a wallet and a digital 
identity are required in order have a viable border health clearance 
mechanism based on Verifiable Credentials. That is certainly not the case.

I was interviewed by a Singapore radio station this week on the topic of 
'vaccine passports' (a misnomer) and they kept reiterating questions 
about what's holding up the adoption of digital identity.  I had to 
explain that, while digital identity does enable selective sharing with 
greater privacy, health clearances for travel do not require travellers 
to adopt a digital identity.  Authorities will continue to check the 
traveller's passport, visas and other identity documents at border 
checkpoints.

Perhaps, as the EFF article states, the real purpose of the California 
digital vaccination card is to screen folks entering restaurants, gyms 
and other establishments serving the public.  In Singapore we have a 
different (and centralised) system for that, known as SafeEntry.  It is 
electronically tied to the Ministry of Health database.
