In this article, you will learn how to add NFC tag reading to an Android app. It registers for auto-starting when the user taps a specific NDEF NFC tag with the phone. In addition, the app reads the NDEF records from the tag.
With around 20,000 downloads, the “NFC / NDEF Library for Proximity APIs” is the most popular NFC library for C#. The library has initially been released in 2012 and has since been extended to cover many standardized as well as common NDEF use cases – also thanks to the support of the netidee open innovation platform.
Lately, the underlying platforms have evolved, and now the library has adapted. The main NFC library has now been ported to .NET Standard, which is a common baseline that makes the library compatible to even more different platforms. The new version 4.1.0 is now available under the open source LGPL license on GitHub, as well as on NuGet.
In addition to running on Windows, the library now fully supports all platforms that support .NET Core (like Linux and Mac), as well as Xamarin for Android and iOS. This makes it significantly easier to provide NFC functionality across different platforms – especially now that the iPhone also finally supports the open NDEF standard within NFC through the Apple Core NFC framework.
A few days ago, Microsoft has released .NET Standard 2.0, which is the new dreams-come-true platform for libraries. Additionally, Portable Class Libraries (PCL) have since also been deprecated. Therefore, it’s about time to port my existing libraries.
