China requires all travelers to provide 10 fingerprints, in addition to a digital photo on entry into the country. This applies to those who require visas ahead of travel, as well as those from visa-free countries.
Data collected during the visa process (if required) or on your initial visit to the country will be used at subsequent visits to verify your identity.
As with many countries, China also retains all accessible biometric data on your passport. This data will vary depending on your nationality.
How long will my data be stored?
There is no public policy on how long your data will be stored. It should be assumed China will retain the data indefinitely.
Who is this information shared with?
Your data is unlikely to be shared with other countries due to China's relationships with other world powers.
What information is required on exit?
On exit the process is similar to entry with one notable difference, if fingerprints have been captured on entry into the country, they are unlikely to request fresh copies on exit.
