A digital guard tour system relies on more than software—it depends on how checkpoints are set up and verified in the field. Each checkpoint “tag” confirms a guard’s presence and ensures accurate, accountable reporting.
The three main options—NFC tags, QR codes, and barcodes—each offer different levels of durability, cost, and security. Choosing the right tag type helps improve accountability, streamline patrols, and match your environment’s needs
NFC Tags: Durable & Secure for Guard Patrols
How They Work:
Near Field Communication (NFC) tags are small, programmable chips that communicate wirelessly with a mobile device or NFC reader when placed within a few centimeters. Guards simply tap their device to the tag to log the checkpoint in the digital guard tour system.
Pros:
- Fast, frictionless scans requiring only a tap
- Durable and weather-resistant for outdoor patrols
- Tamper-resistant and difficult to duplicate
- No line-of-sight needed; can be hidden for aesthetics or security
Cons:
- Higher cost per tag compared to QR codes or barcodes
- Requires NFC-capable devices
- More effort to install or replace
Best Use Cases:
- Outdoor or harsh environments
- High-security facilities where tamper prevention is critical
- Fast-paced patrols where scanning efficiency matters
QR Codes: Cost-Effective Checkpoints for Digital Guard Tours
How They Work:
Quick Response (QR) codes are printed 2D patterns that can be scanned using a smartphone camera or QR reader. Scanning the code logs the checkpoint into the digital guard tour system.
Pros:
- Extremely low cost; can be printed on stickers or signage
- Easy to replace if damaged
- Works on any camera-enabled device
- Customizable with branding
Cons:
- Requires line-of-sight to scan
- Vulnerable to wear, fading, and vandalism
- Easier to duplicate than NFC tags
Best Use Cases:
- Indoor environments with controlled access
- Sites needing frequent checkpoint replacement
- Low- to medium-security operations
Barcodes: Simple, Compact Guard Tour Options
How They Work:
Barcodes are one-dimensional printed patterns that require a barcode scanner or compatible device to register the checkpoint.
Pros:
- Universally recognized and supported
- Very low cost, similar to QR codes
- Compact size for small or discreet checkpoints.
Cons:
- Stores less information than QR codes
- Requires line-of-sight to scan
- More prone to read errors from dirt or scratches
Best Use Cases:
- Facilities already using barcode scanners in daily operations
- Environments needing discreet checkpoints
- Legacy patrol systems upgrading to digital without replacing hardware

Choosing the Right Checkpoint for Your Digital Guard Tour System
The right checkpoint technology depends on your organization’s needs:
- Speed and durability matter most → NFC tags
- Low-cost, quick replacement is critical → QR codes
- Integration with existing barcode systems → Barcodes
In practice, many organizations choose a hybrid approach—using NFC tags in outdoor or high-security areas, while placing QR codes or barcodes indoors. This ensures flexibility, reduces costs, and supports patrol workflows across environments.
Matching Technology to Patrol Success
The right checkpoint strategy ensures your digital guard tour system is accurate, efficient, and secure. Integrated with tools like incident reporting and security dispatch, it helps teams across campus security, healthcare, corporate, and law enforcement streamline patrols and improve accountability.
