We also offer a free Covid QR generator for popular Covid QR codes

A. QR Check app

  • Currently Covid vaccination certificates (also called Covid passports, health passes, passes) in Israel, India, EU, California (US), Montreal (Canada) and other locations all use different QR codes.   Several organizations (VCI, Good Health Pass, etc.) have proposed global standards.

PathCheck is one of the few organizations that supporting offers two open source applications
