Visitor Management Systems: Face Recognition, QR Passes and Logs

Beyond the paper register

The paper visitor register at the security desk is slow, often illegible, easy to fill with fake details, and impossible to search after an incident. Digital visitor management captures who came, whom they met, when they arrived and left, and a photo — in seconds.

Paper register vs digital system

How a modern visitor flow works

• The host pre-registers the visitor, who receives a QR pass by SMS or email.
• At reception, the visitor scans the QR or registers on a kiosk or tablet.
• The system captures a photo and, where required, an ID document.
• The host gets a notification and approves the visit.
• A printed badge or temporary QR or face access lets the visitor through turnstiles or doors.
• Check-out is recorded at exit, and passes expire automatically.

Face recognition for visitors

Visitor management can enrol a visitor’s face temporarily so face terminals at doors and turnstiles admit them only to approved areas, only for the visit. Access expires automatically. Frequent visitors such as vendors can be given longer passes.

Visitor types and rules

• Business visitors: pre-registered by the host, escorted to meeting areas.
• Vendors and service engineers: longer passes, specific areas, work permits where needed.
• Delivery staff: limited to reception or the goods entry; no access inside.
• Interview candidates: pre-registered by HR, limited to reception and interview rooms.
• Contractors: photo, ID and contractor company; safety induction before entry in factories.
• Blacklisted persons: flagged at check-in so the guard can refuse entry.

Where it is used

• Offices and IT parks.
• Factories, for vendors, drivers and contractors.
• Apartments, for guests, deliveries and domestic staff.
• Schools, for parents and visitors.
• Hospitals, for visitor hours and restricted areas.

Evacuations and emergencies

In a fire alarm or evacuation, the most important question is who is still inside. A digital visitor system gives the security team a live list of visitors on site, with their host and photo, alongside the employee attendance list. Paper registers cannot do this reliably.

Data protection

Visitor names, phone numbers, photos and IDs are personal data. Collect only what you need, tell visitors why, keep records for a defined period and then delete them, and restrict access. Avoid storing full copies of Aadhaar; where ID is needed, record only what is necessary.

Handling ID documents and Aadhaar

Many sites ask for ID at the gate. Collect ID only where there is a real need, such as factories, labs and data centres. UIDAI encourages people to share masked Aadhaar, which hides all but the last four digits, and the Aadhaar Act restricts how Aadhaar numbers may be stored and shared. A practical approach is to record the ID type and last few digits, or verify the ID visually, rather than storing full copies.
