LG replaces passwords with secret sequence of taps in new phone:
- Knock codes can consist of between two and eight knocks.
- System can recognise 86,367 different cmbinations. How it works: Users can program in their preferred knock code of between two and eight knock with gaps inbetween.By tapping the pattern anywhere on the phone, sesnors can detect knocking and process the code.If it matches the users, the handset is woken up and unlocked without the need for a passcode.
