India uses hand-stamping; airline and railway reservation data for contact tracing and quarantine enforcement

India has begun stamping the hands of people arriving at airports in the states of Maharashtra and Karnataka to specify the date until which they must remain in quarantine. The government is also using airline and railway reservation data to track suspected infections and find hand-stamped people who had promised not to travel. Kerala authorities have used telephone call records, CCTV footage, and mobile phone GPS systems to trace contracts of COVID-19 patients, and published detailed time and date maps showing the movement of people who have tested positive.
