QR Code vs NFC vs GPS for Patrol Check-Ins
Choose NFC when a worker should bring a phone close to a fixed checkpoint. Choose QR codes when easy printing and replacement matter most. Choose a GPS Point when an outdoor visit needs location validation without installing a tag. Virtual Points suit steps that do not require a physical location check.
The right choice depends on the work and the site. An indoor plant-room inspection, a cleaning round and a visit to an open parking area do not need identical checkpoints. TARGPatrol supports these four Point types, so a workflow can use more than one method.
Reviewed November 10, 2026. This comparison separates checkpoint check-ins from continuous location tracking and explains where NFC fits within RFID.
Compare checkpoint methods
Method | Employee action | Useful for | Main limitation |
|---|---|---|---|
NFC | Bring a compatible phone close to an installed tag in the app's scanning flow | Fixed indoor checkpoints, low-light patrols and equipment checks | Requires a compatible phone and tag; metal surfaces need suitable mounting |
QR code | Scan a printed code with the phone camera | Low-cost pilots and easily replaced checkpoint labels | A visible code can be copied; lighting and label condition affect scanning |
GPS Point | Start a check-in near the Point's saved coordinates | Outdoor or distributed locations without physical labels | Location permission and sufficient accuracy are needed; indoor positioning can be unreliable |
Virtual Point | Complete the step in the app without a physical scan | Instructions or checks that do not require location verification | Does not establish presence at a physical checkpoint |
These methods identify the work context in different ways. None, by itself, proves that the employee completed every required action. Pair the checkpoint with relevant checklist answers, notes or photos.
When NFC is the better fit
NFC is useful when the worker needs to interact with a particular installed checkpoint. A guard can tap a tag beside a door without focusing a camera; a technician can use a tag at an equipment inspection point. Passive NFC tags do not need batteries.
Choose the tag for its mounting surface and environment. A basic sticker and a rugged on-metal tag are not interchangeable. Test the actual phone, app and tag at the intended mounting point before ordering a large batch. The NFC tag selection guide explains these choices.
Close-range reading is useful, but it is not an anti-fraud guarantee. Some tags can be copied or moved. Restrict changes to Point identifiers, protect the mounting and review the work recorded alongside the scan. For setup and rollout guidance, read the NFC guard tour guide.
NFC and RFID are not interchangeable labels
RFID includes several radio technologies. NFC is a short-range form of HF RFID used by compatible smartphones. A tag sold simply as RFID may require a different reader and may not work with the phone.
TARGPatrol's phone-based tag check-ins use compatible NFC tags. They are not the same as a long-range RFID inventory system or a door access controller. If you are replacing dedicated patrol hardware, check the existing tag standard first. The RFID guard tour system guide explains the purchasing and migration questions.
When QR codes are the simpler choice
QR codes are practical when a team wants to print and place checkpoint labels quickly. They do not require NFC hardware, and replacement labels are easy to produce. A protected, readable label can work at many types of site; QR is not limited to small buildings.
The trade-off is visibility. The employee needs a readable code and enough light for the camera. A photograph or duplicate of a code can be scanned away from the original label, so a QR scan alone is weak evidence of presence. Add work-specific evidence and review exceptions where location matters.
For setup, use the QR patrol quick-start guide.
When GPS Points make sense
A GPS Point removes the need to install a physical label. The employee actively starts a check-in, and TARGPatrol checks proximity to the Point's saved coordinates. It can suit an outdoor gate, parking area or temporary work location.
GPS accuracy varies. A coordinate check cannot reliably distinguish nearby rooms or floors, and the device needs location permission and usable positioning data. TARGPatrol uses a 50-meter base limit plus the accuracy reported by the device; there is no per-Point radius setting. Test the check-in at the actual site. See GPS Point proximity validation.
A GPS Point check-in is separate from optional GPS tracking and Location geofencing. Tracking records coordinates for enabled users while the mobile app is active; it also requires location permission and a selected Location. Location geofencing uses a configured site boundary and requires a paid plan. Neither turns an NFC tap into continuous tracking. The GPS tracking guide explains the separate settings.
Where virtual Points and Bluetooth fit
Use a Virtual Point for a step that does not need a physical scan, such as reading an instruction or recording a final handover note. It should not be presented to a client as proof that someone visited a specific place.
Bluetooth beacon detection is a different approach used by some systems. It is not one of the four TARGPatrol Point types compared here. Do not plan a hands-free beacon check-in workflow on the assumption that NFC support includes Bluetooth support.
Use a mix of checkpoints on one site
For an illustrative warehouse workflow, NFC tags can identify indoor equipment checkpoints, QR labels can support a short pilot at accessible cleaning stations, and a GPS Point can validate an outdoor arrival. A Virtual Point can hold the final handover step. The choice for each step follows the evidence needed, not a requirement to use one technology everywhere.
In TARGPatrol inspections and audits, the checkpoint is part of the work process. Employees complete the configured actions and can report an Incident when a finding needs follow-up. Managers review synchronized results and supporting evidence.
Use Scheduled Tasks for planned, assigned work. For additional visits, enable On-Demand Check-ins for authorized users at the relevant Points. The same physical checkpoint can support both workflows with the appropriate configuration.
Run a short pilot before standardizing
Identify what each checkpoint must establish: proximity, an inspection result or simply completion of an instruction.
Test the selected method with the actual phones, surfaces and lighting conditions.
Prepare the required work online, then test supported offline task execution and later synchronization. A physical scan does not mean the server has received the result.
Check that the manager can find the expected answers, photos and unresolved Incidents.
Agree how employees should report a damaged label, an unreadable tag or unavailable GPS instead of silently bypassing the check.
