QR codes are a wild and woolly bunch. Your vanilla QR code will be an https: (or http:) URL.
For the purposes of associating with WiFi, the QR code may begin with WIFI:
For the purposes of sending an SMS, the QR code may begin with SMSTO: (and the full text in the QR code will be SMSTO:destination-mobile-number:text-of-message)
Let’s call them all URLs where the schemes in the latter cases are WIFI and SMSTO respectively.
I have two questions.
- Right now is there any command line to do anything with an SMSTO URL i.e. that would send the required SMS (or at least launch an SMS sending application in preparation for sending the SMS - since the user really ought to be given the opportunity not to go ahead and send the SMS)?
- Is there any official registry of these additional schemes or is it a free-for-all? (This question is really just for interest.)
