HISO 10067:2021 COVID-19 Contact Tracing QR Code and NFC Tag Specification

This document updates the COVID-19 Contact Tracing QR Code Specification to include NFC tags. This standard: defines the data and format to be included in NZ COVID Tracer QR codes and NFC tags; specifies the standard quality and behaviour of NZ COVID Tracer NFC tags.

The NZ COVID Tracer app has been operational in New Zealand since May 2020. It allows users to create a private digital diary of their movements, primarily by scanning QR codes containing name and address details and a unique Global Location Number (GLN) for the venue visited. 

The capability to add a diary entry equivalent to scanning a QR code by tapping an NFC tag was added to the NZ COVID Tracer app in August 2021. Businesses can display Near Field Communications (NFC) tags in addition to QR codes. This provides an alternative for consumers to address the following issues in scanning QR codes:

  • Scanning QR codes can be difficult for people with some accessibility needs – for example, framing the QR code correctly within the camera view of the app can be difficult for people with low vision, and holding the device steadily at the correct angle can be difficult for some people with a physical impairment. NFC tags may be more accessible for some of these people.
  • Scanning QR codes with the NZ COVID Tracer app requires a user to first open the app, which may be inconvenient. Tapping an NFC tag can allow for much quicker check-in without needing to launch the app.

The NFC functionality uses the existing data content of QR codes and does not compromise the privacy and security of the app. This revision of the standard incorporates the technical specification of the NFC tags.
