The UK may be rethinking its decision to shun Apple and Google’s API for its national coronavirus contacts tracing app, according to the Financial Times, which reported yesterday that the government is paying an IT supplier to investigate whether it can integrate the tech giants’ approach after all.

As we’ve reported before coronavirus contacts tracing apps are a new technology which aims to repurpose smartphones’ Bluetooth signals and device proximity to try to estimate individuals’ infection risk.
