Your signature
Your signature, in the menu under your initials at the top right.
Your signature is the one drawn above your name on every letter and prescription you sign. It is kept on your own contact card. Your signature shows the one stored now, or says you have none, in which case letters you sign print with your name and no signature.
Add your signature, or Replace it, shows a code to scan with your phone. The page it opens has a box to sign in with your finger: Clear starts again and Save stores it, in place of any before it. The code is yours alone and lasts twenty minutes. Or sign on this device opens the same box on the computer you are using.
Where you are about to make or sign a letter and have no signature stored, the same offer appears there, with Add your signature, and says when your phone has stored it.
