After getting the vaccine, individuals are sent a code which allows them to download the certificates.
The national health department launched e-certificates on Friday after several days of live testing.
EVDS project manager Milani Wolmarans told TimesLIVE necessary security steps were being taken to prevent leaking of personal information.
She said while vaccinated individuals can call the Covid-19 hotline to retrieve their codes, the department will resend them in batches over time to ensure no-one loses their code.
Health minister Joe Phaahla said the e-certificates would allow people access to certain places not open to unvaccinated people, and would also be used for “discounts and prizes”.
Vaccinated individuals are already reaping the benefits.
On Tuesday, 2,000 soccer fans and staff were in attendance for Bafana Bafana’s match against Ethiopia at the FNB stadium in Soweto. This was the first time fans have been allowed in stadiums since the start of the Covid-19 pandemic early last year.
