The project spec was to deliver an access entry system for construction sites. However the company didn't want any physical infrastructure on site. Neither did they want any physical barriers or gate staff to have to be deployed.
In the end we settled on a QR code type entry system, which will work with no physical infrastructure and can be used by site contractors using any modern smartphone.
