In-depth information on Savitas QR.
How it works

What is the process in short steps?

A short overview of the way Savitas QR operates.
  1. An organization purchases Savitas QR codes, and applies them within their facilities in places where social distancing may be a challenge;
  2. When employees are returning to their work environment, they are asked to scan Savitas QR codes when they encounter one. There is no registration or login required, to ensure total privacy and to keep it speedy;
  3. The unique Savitas QR codes are stored on their smartphones bundled with the timeslot when the code was scanned. But first they are hashed up together in a unique way such that verification can be done without storing the original information;
  4. When employee John experiences symptoms of the disease, he contacts a doctor who determines that he has contracted COVID-19, and gives John an illness note which John must deliver to his employer. On that note (in Belgium) the COVID-19 diagnosis is indicated. Upon receipt of that note, one of the appointed delegates within the organisation (the company doctor, someone from HR...) gives John an anonymous authorisation code which he must use to mark himself as “infected”, upon which his scanned records are uploaded to the server as “infectious”;
  5. Susan, who was in the same meeting as John, scanned the same QR code as John within a infectious timeframe;
  6. If that is the case, next time Susan checks her status or scans a QR code, the most recent scans are fetched from the server and compared with records stored on her smartphone;
  7. If there is a match with her records a message is displayed on Susan’s phone that she needs to take action (self-isolate, contact a doctor…). This way, she gets notified of a possible infection days before she may show symptoms herself, and by her actions she helps to stop further infection. But only Susan will ever know, as this information never leaves her phone.
