This could potentially be useful to some people with some disabilities. Perhaps it could also be useful to a person trying to amke a telephone call from a mobile telephone in cold weather where he or she would prefer not to need to remove his or her gloves to make the call.

Inasmuch as QR codes are already able to encode telephone numbers (at
least in the US, and I have assumed in the rest of the world as well), I
don't see any utility in this, since it would force the user to scan the
codes in sequence. whereas a QR code containing a full number would only
need to be scanned once, and in at least some phones and software, the
scan would initiate dialing.
