How To Unlock Your Door By Using Your iPhone As Your NFC Key Card

With future beta releases of iOS 11, many are hoping that Apple will relax its tight grip over NFC use, and while there’s a rumor that it may do that by granting access to third-party developers, it may not. So if you want to make further use of your iPhone, we’re going to show you how to use it as an NFC Key Card.

If the possibility of using your NFC for more than paying with Apple Pay sounds ridiculous or unbelievable, believe us when we say that it isn’t; however, there are some requirements to make it possible. Thankfully, one is not waiting for Apple to make it possible, as there are many developers working to do so.

You need an iPhone 6 or newer, which currently includes the iPhone 6s, 6s Plus, SE, 7, and 7 Plus. However, the iPhone must be jailbroken and running iOS 10. You also need the NFCWriter tweak installed. From there, you are ready to take advantage of something those without a jailbreak can not.

What is NFCWriter?

As previously mentioned, iOS devices are not capable of using NFC to its full potential. NFCWriter simply unlocks the NFC chip, which makes this tweak a must-have if you are partial to forgetting your NFC key cards. You will now be able to program your device to act as a replacement and much more.

Interested in finding out more? You must first purchase NFCWriter from Cydia’s BigBoss repository for $3.99. Then you will be ready to follow the guide below; as always, if you have doubts, please ask. Or alternatively, do some further research before following the steps below. Either way, when you do free your NFC chip, you won’t regret it.

While this guide is a simple one, it is advised that you read and then act upon each step individually. This approach has been proven to be the most effective at reducing mistakes from happening.

1. With your jailbroken iPhone ready and NFCWriter installed on it, scan your NFC access card.

2. Next, you will be required to jot down the existing card’s serial number. You will need it for the following step.

3. Enter that serial number into NFCWriter’s Tag Emulation area.

4. When the serial number has been entered, select Start Tag Emulation, and that’s it. Should you ever find yourself without your work access card again, you can use your iPhone.

However, we advise that you ask for permission from your boss or whoever is responsible for securing staff access to the building. You wouldn’t want to get into any kind of trouble if something goes wrong.
