Visitor Management

Visitor management is a system that manages outside people who visit facilities such as office buildings, factories, hospitals, and schools, from reception to departure. Its main purposes are ensuring security, keeping visit records, and knowing who is in the building in an emergency.

QR codes are widely used to make visitor management more efficient. When a visit is booked, an entry pass with a QR code is sent by email, and the visitor completes the entry procedure simply by showing the QR code on their smartphone at reception. Filling in paper visitor cards and manual checks by reception staff become unnecessary, and the waiting time at reception is greatly shortened.

In terms of security, setting an expiration date and a one-time token on the QR code can prevent unauthorized use. A QR code that is valid only for the date and time of the visit cannot be used the next day. Invalidating a QR code once it has been scanned also prevents re-entry with the same code.

Since the COVID-19 pandemic, demand for contactless visitor management has grown, and QR code-based systems have spread rapidly. A method in which visitors show the QR code on their own smartphones avoids contact with shared terminals, so it is also better for hygiene.
