Recipients of the Covid-19 vaccine may eventually be given digital health credentials in order to travel, go to work or school, visit entertainment venues, and more.
Supporters of digital vaccine credentials say they could help control the virus, reopen the economy, and give consumers peace of mind, but there are concerns that these digital passes would make it difficult for people with limited access to vaccines or online verification tools to work or engage in other activities.
Tech companies working on Covid-19 health pass apps, however, contend that they are more reliable than paper health documents, which could be forged, and that their systems have been designed to mitigate privacy risks.
