How to scan NFC tags without unlocking your device
The range of NFC is short – about 4 inches or 10 centimeters. But they are faster than the usual QR or barcode. To scan these tags, all you need to do is unlock your NFC-enabled device and scan it. But there is a practical module that makes work even easier for you. You won’t even have to unlock your device to scan for these NFC tags. Just put your locked devices next to a tag and you’re done. Before listing the steps to follow, there are a few important points to remember.
Important points to keep in mind
- To scan NFC tags without unlocking your device, you will need a rooted Android device.
- You must also have Magisk Manager installed on your device.
- It is not a modification without system because it directly corrects and modifies the system file NfcNci.apk. This could therefore break the SafetyNet.
- Therefore, it does not work with NFC payments. Well, you could view this limitation as a disguised blessing. Indeed, making contactless payments in locked devices is never a good idea from a security perspective.
- Flashing this module to analyze NFC tags can lead to the formation of brick devices or also cause startup loops. In such a case, DroidViews or one of its members will not be considered reliable. Go ahead at your own risk. However, in the case of a boot loop, you can uninstall the module via TWRP Recovery.
