TKey Interaction points

TKey has two LED’s indicating status and one touch area.

Power LED illuminates blue, when TKey is powered.

Status LED indicates different statuses. There are two basic indications:
When TKey has booted up status LED illuminates in white.
Red blink means something is wrong, restart TKey by removing it from USB port and re-insert.
Green blink means user has to assert presence. This behaviour depends on the TKey device app.

Touch sensor area is where user places a finger to assert presence.
User should gently place a finger on the area for a second or two.
For security reasons, the touch sensor is designed to avoid registering positive false, i.e. a touch is registered when no finger has been placed on the touch area. The downside is that user sometimes have to touch the area two-three times for the TKey to correctly register a touch.
