Checkpoint scanning has revolutionised security patrol verification. By placing QR codes or NFC tags at strategic locations around a client site, you create a verifiable digital record of exactly when each point was visited — replacing trust with evidence.
How Checkpoint Systems Work
Physical tags — QR codes printed on weatherproof labels, or NFC chips in durable housings — are fixed at key locations around the patrol route. Guards scan each tag using their mobile phone as they patrol. The system records the tag location, the time of scan, and the guard’s identity, building a complete patrol record.
QR codes have the advantage of working with any smartphone camera. NFC tags require a phone with NFC capability but can be scanned faster and through cases. Both technologies are inexpensive and reliable.
Placement Strategy
Place checkpoints at security-critical locations: main entrances, fire exits, car parks, perimeters, plant rooms, and any areas identified as high-risk in the site survey. The number and placement should ensure that completing all scans requires the guard to physically patrol the entire site.
Avoid placing all checkpoints along a single corridor — spread them to ensure comprehensive site coverage. Include both internal and external points to verify that external patrols are actually being conducted in poor weather.
Operational Benefits
Checkpoint data provides undeniable evidence that patrols are being conducted as contracted. This is powerful in client reporting — a monthly summary showing 100% patrol completion is far more convincing than a guard’s daily occurrence book entry saying “patrol completed.”
Management can identify patterns: which guards consistently miss certain checkpoints, which checkpoints take unusually long to reach (suggesting blocked routes), and whether patrol times are realistic or indicate rushing.
Client Confidence
Sharing real-time or daily checkpoint reports with clients demonstrates transparency and accountability. Clients can see exactly when their site was patrolled and which areas were covered. This level of evidence is increasingly expected in tender submissions and contract renewals, and companies that can provide it have a significant advantage over those relying on paper-based patrol logs.
