Fingerprinting.

Fingerprint

All visitors to Britain requiring visas will have to be fingerprinted starting yesterday, the government said. Immigration Minister Liam Byrne said those applying for a British visa from any of 133 countries would now have their fingerprints checked against a database.
Byrne said the system, which the government has gradually been introducing around the world since September 2006, had already captured biometric information from more than 1 million people. He said the system had flagged nearly 500 cases of identity fraud.
Logging and checking visitors’ biometric information is one of the central planks of the government’s new immigration strategy, which includes the introduction of an Australian-style points system intended to encourage skilled immigrants.
