Apple has placed limitations on developers building “vaccine passport” apps – ones that entitle the bearer access to somewhere based on a COVID test or vaccine.
It said it had noticed an increase in such apps that generate “passes” used to access locations or services.
But such apps will no longer be allowed unless they are working with recognised public health authorities or companies associated with them.
That includes “test kit manufacturers, laboratories, or healthcare providers” as well as government and medical institutions, Apple said.
The change is designed “to ensure these apps responsibly handle sensitive data and provide reliable functionality.”
It is the latest hurdle for so-called vaccine passports, which have long been proposed as an eventual alternative solution to lockdowns.
But UK think tank the Ada Lovelace Institute, which looks at how big data affects society, warned that such a system could present a host of issues.
