Unlike GPS based location technology, proximity tech does not measure where a handset (i.e. person) is. It measures how much distance (from cm…m) between two or more person and when, how often and for how long this contact existed. One such proximity solution is www.p2pkit.io from Uepaa AG in Zurich – an ETH spin-off. It has been used in multiple commercial apps, such as Xing with up to 15 Million monthly active users. We are open and fully prepared to help and support any government effort to make full use of proximity technology in their apps and to fight against COVID-19!
