Discreet keypad prevents 'shoulder surfing' security attacks

Passcode-equipped doors might look good and remind you of scenes from the latest Bond film, but they can leave you exposed. To prevent people from looking over your shoulder and stealing your pin, South Korean designer Kwon Hyuk-sang has created a door handle that features a discreet keypad with built-in braille. That means safer passcodes, less unwanted visitors and more peace of mind.

As Kwon describes on the mock-up product poster:

When entering the PIN, the greatest security threat is shoulder surfing attack. Shoulder surfing attack is watching the pin being entered from over the shoulder to obtain the number. It is the most common and powerful security threat of stealing the PIN.
