Wait, it is 6 touch zones? I had opened issues with suggests under a different assumption. I thought those touch zones were basically two, where you would get an x value between 0 and 1. Scrolling uses that, doesn't it?
With its invisible touch sensors on its sides, the BitBox02 keeps a stealthy appearance while having excellent flexibility for its inputs.
The 6 touch zones enable alphanumeric device passwords, which increase the security of your wallet compared to simple numerical passwords.

Yes, it's more or less "infinite" touch zones. For unlocking, they are split in 6 discrete zones for typing, changing character type, removing and confirming.
