British Airports Authority (BAA) have recently introduced new security measures which will apply when you take a domestic flight within the UK

Whenever you transfer through London Heathrow Terminal 1 onto a UK domestic flight you will find that there is a new security procedure - Biometrics. This increases security but also means you will be able to use the retail, leisure and dining facilities available airside to international customers at Terminal 1.

Biometrics consists of electronic fingerprinting and a facial digital photograph, which will be taken at the entrance to the departure lounge and checked again at the boarding gate.
Afterwards the records are deleted so don’t worry about your details being kept on file.

... or being lost on the bus. Forgive me if I don't fully trust their data protection procedures.

I believe this is a precursor for Terminal 5 for BA passengers only which will have a common departure lounge for international and domestic passengers...
