Thinking about my signature over the years causes me to believe that the process is of declining value:
- my signature has varied--usually I've signed "William D. Harshaw", but occasionally "William David..." I use "Bill..." for less official occasions.
- my bank may still have my 1968 signature on file, although perhaps it's been updated. IIRC when I bought the house in 1976 I had to go to an officer of the bank to convince him I was me, because the difference in signatures over the 8 years was great enough to raise doubts.
- but that was back in the day when I made payments by check, signing 5 or more checks each month. These days I likely write 5 or more checks in a year, so whenever I sign a check I'm really out of practice. I'd predict that means my signature is more variable these days.
- I usually use a debt card instead of a credit card, but when I use the credit card I often have to sign using my finger on a tablet, not using a pen. My tablet signal bears only a slight resemblance to my pen and ink signature.
So my bottom line is the bureaucracy should begin to steer away from signatures as a proof of identity.
