Apple and Google have released a joint API to notify people about possible contact with coronavirus infected.
Any country can embed this API in its application to track contacts with virus carriers.. Currently, three US states want to use technology: Alabama, South Carolina and North Dakota.
Also about 20 стран заинтересовались API Apple и Google. Какие именно, not specified.
API уже встроен в iOS 13.5. Когда смартфоны на Android получат его, зависит от производителей.
