Near field communication

Near field communication (NFC) is by far the most popular proof of presence solution. It’s successful in built-up environment, good value and energy efficient.=

GPS and NFC are the most reliable technology for organisation wide usage.
Security Patrol – Ultimate Guide to Security Patrols Security patrols are a staple of the security function. Not only do they inspect a site’s security and safety measures but also, they gather intelligence and counter threats. For thousands of years these patrols have kept people and assets safe. But, today technology is changing the security patrol. A patrol no longer needs people to perform them and people are no longer the only threat.

Frequently Asked Questions

How many NFC Tags can be used?

You can use as many tags as you like. Most organisations will use 100-200 tags but some use thousands.

What phones can I use for proof of presence

We recommend a number of Android devices. Apple has recently made NFC available for proof of presence. However, we don’t yet offer proof of presence on Apple (we don’t consider the feature sufficiently tested). Take a look at our list of top tough phones here.

Why doesn't NFC work on my phone?

Check to ensure you have your phone’s NFC switched on (go to your phone’s ‘Settings’ menu). If NFC is switched on and you still don’t receive a reading then check the NFC tag. You may also consider the phone chip being faulty. Additionally, if you have the phone housed in a tough case then that may be blocking the signal.

Is GPS good for proof of presence?

If you want an accurate proof of presence reading then using a phone’s GPS is not ideal. GPS is frequently inaccruate and only provides gives a grid reference. This is not helpful if you want to identify a location above or below ground.

What are the best NFC Tags?

There are many NFC tags available. As a result, we have written a best NFC tags guide to help you choose the right kind of tag.
