If the day arrives when biometrics replaces my signature I will likely be exterminated same as
the day they take my guns and property. I doubt I live long enough to see this happen in the small rural community I grew up in and live.
Certainly your fingerprint is a hell of a lot more secure than a signature. I believe its the newest Android or Iphone that already uses biometrics for security. Unless you're in your 80s, you'll likely see the beginning of this.
