## INTRODUCTION
To reduce the spread of [COVID-19](https://www.ecdc.europa.eu/en/covid-19-pandemic) it is necessary to inform people about their close proximity to positively tested individuals. So far, health departments and citizens identified these in personal dialogues based on people’s memory, which led to a high number of unknown connections, e.g. when using public transport.

- (1) When a test is conducted, they receive an information flyer with a custom QR code. The code is either created on-site or is already available as a stack of pre-printed QR codes. The QR code contains a globally unique identifier (GUID).
- (2) Optionally, they can scan the QR code with the Corona-Warn-App (*Figure 3*, step 1) – if users decide against using the test retrieval functionality of the Corona-Warn-App, they still receive their test results through the regular channels explained before.
- (3) When the code is scanned, a web service call (REST) is placed against the Verification Server (*Figure 3*, step 2), linking the phone with the data from the QR code through a registration token, which is generated on the server (*Figure 3*, step 3) and stored on the phone (*Figure 3*, step 4).
