Most guard management systems today include a digital accountability tool that replaces the traditional guard tour wand and proves officers are hitting their stops at the assigned times. The most common checkpoint technologies are QR codes, NFC tags and RFID tags, and each has strengths.

This article explains what each technology is, the three biggest advantages QR codes offer, where NFC or GPS may be a better fit, and how a TrackTik guard tour system lets you use the right method for every location.

Key takeaways

  • QR codes are the lowest-cost checkpoint option.
    They cost almost nothing to print and work with any camera-equipped smartphone.
  • QR codes are the fastest to deploy.
    You can print replacements on demand instead of waiting for tags to ship.
  • NFC is harder to fake.
    Because NFC requires the phone to be within a few centimeters of the tag, it suits high-security areas like server rooms and access doors.
  • GPS covers what you cannot tag.
    Geofenced checkpoints work well for outdoor perimeters and large open areas.
  • The best tours mix methods.
    TrackTik supports QR code, NFC, barcode, GPS and manual check-ins in the same tour, so each location gets the right level of verification.

QR Codes vs. RFID vs. NFC

Before comparing the pros and cons, here is a quick definition of each technology:

  • QR (Quick Response) code: QR codes are similar to barcodes and can be scanned quickly by any camera-equipped smartphone.
  • RFID (Radio Frequency Identification): RFID chips can be embedded or placed around a site and emit low-level radio signals that are read with specialized equipment. Both short-range and long-range tags exist, but short-range tags are most common in security.
  • NFC (Near Field Communication) tag: NFC is a short-range wireless technology that exchanges data when a phone is held very close to a tag. It is the same technology behind mobile wallets, and today most smartphones have NFC built in.

3 Advantages of QR Codes for Guard Tours

1. QR Codes Are Low Cost

RFID and NFC tags are relatively inexpensive, but when you use a large number of them across many properties, the cost adds up. QR codes cost almost nothing. You just generate them and print them.

QR codes also don’t require additional equipment. Whether you use company phones or a bring your own device (BYOD) policy, nearly any smartphone or tablet can read them. RFID tags, on the other hand, require dedicated readers that add to the cost of every deployment.

On cost alone, QR codes are hard to beat. All you need is a printer and durable label stock.

2. QR Codes Are Easy to Deploy and Replace

With NFC and RFID tags, you have to wait for the manufacturer to ship more when you run out. QR codes can be printed whenever you need them, and relatively inexpensive portable label printers can create them on site if you want that added convenience.

Officers are also likely to have used QR codes before, so there is little to no training needed. None of these technologies are difficult to use, but familiarity helps new officers get up to speed faster with the TrackTik security guard tour app.

3. QR Codes Offer Flexible Placement

Embedding chips or tags on site can be a laborious process. You have to visit each location, make sure each tag is properly attached and keep checking that tags haven’t been damaged, removed or stolen.

QR codes are more flexible. Some operations even keep checkpoint codes in a binder or book that officers carry, especially where they can’t post codes on walls. When an officer reaches the location, they scan the matching code with their phone. This approach is similar to running guard tours without physical checkpoints.

If you use this approach, pair each scan with GPS location and a required photo of the site. Without those controls, a carried code could be scanned from anywhere, so the extra verification is what preserves true accountability and proves officers are actually on site.

When NFC or GPS Is the Better Choice

QR codes are a great fit for many locations, but they are not always the right tool. Consider other methods in these situations:

  • High-security areas: NFC requires the phone to be within a few centimeters of the tag and can’t be scanned from a photo, which makes it a strong choice for server rooms, access doors and secured assets. Learn more about enterprise guard tour systems with NFC integration.
  • Harsh environments: Printed codes can fade or get damaged outdoors, while durable NFC tags hold up better in weather and high-traffic areas.
  • Outdoor perimeters and open areas: GPS geofenced checkpoints verify presence where you can’t mount a tag, and they work well for mobile patrol routes.
  • Low-risk interior stops: QR codes remain the fastest and lowest-cost option for routine checkpoints.

Getting the Most From Your Checkpoints With TrackTik

This isn’t a choice you have to make once. All of these methods can work well, and the strongest guard tour programs match the method to each location. TrackTik, the security workforce management platform from Trackforce, supports QR code, NFC, barcode, GPS and manual check-ins in the same tour.

Setting up checkpoints well helps you go beyond accountability to improve guard management and reduce training time. No matter the size of your security operation, you can request TrackTik pricing based on your sites and modules, or book a TrackTik demo to see mixed checkpoint tours in action.

Frequently Asked Questions

Each has strengths. QR codes are the lowest-cost and fastest option to deploy, while NFC tags are harder to fake because they require the phone to be within a few centimeters of the tag. Most security operations get the best results by mixing methods, and a TrackTik guard tour system supports both in the same tour.

QR codes cost almost nothing to print, work with any camera-equipped smartphone, can be replaced on demand without waiting for shipments and are familiar to most officers. They are a strong choice for low-risk interior checkpoints and fast rollouts.

A printed code can be photographed or copied, which is why QR checkpoints work best with added verification. Pairing each scan with GPS location, time stamps and a required photo makes it much harder for an officer to scan without being on site. For the highest-security areas, NFC is the stronger option.

Not usually. NFC is built into most modern smartphones, so officers can scan NFC tags with the same phone they use for QR codes. RFID is different, since it typically requires a dedicated reader.

NFC is a specific type of short-range RFID designed to work with smartphones. Traditional RFID guard tour systems usually need dedicated readers, while NFC tags can be read by the officer’s phone, which makes NFC easier and more affordable to deploy.

Use GPS geofenced checkpoints for outdoor perimeters, parking lots, construction sites and other large open areas where mounting a tag is impractical. TrackTik mobile patrol also uses GPS to track patrol route progress in real time.

TrackTik supports QR code, NFC, barcode, GPS and manual check-ins, and each checkpoint can trigger actions like logging an incident, displaying instructions or opening a report form. Checkpoint data feeds TrackTik business intelligence so you can prove patrol coverage to clients. Book a TrackTik demo to see it in action.
