QR Code Or Barcode For Vistor Check-In?

I have a customer who is looking for an automated system to provide QR Code or Barcode access for visitors through their speedgates which are installed at their office. The system would need to work in conjunction with their visitor management platform to generate and print a unique temporary QR Code or Barcode for visitors which they can then present at the speedgate.

Does anyone know of any products on the market that can do this?

The goal is for the reception to only be manned part time, without concierge having to be there full time proving visitor access cards all day.
