What's the big deal with QR codes?

With Covid-19 we are all more familiar with QR codes: every time we go to a cafe or enter a shop you can register your attendance by a 10-second scan of the QR code and entering your details.You may not be surprised to know that HosPortal healthcare scheduling software was there first with an even better solution. Events, meetings and other calendar items can have QR codes attached to them to record attendance. The QR code is only valid around the time the meeting is on. And because it is linked to each user's account there is no need for them to enter names and contact details: their attendance is automatically recorded and time-stamped...it takes about 1 second.
