I would like to ask what devices this library supports. I am currently searching for a solution to create a node app using node-webkit that reads/writes Tags using a http://www.acs.com.hk/en/products/3/acr122u-usb-nfc-reader reader.

Found an option by creating a Chrome App (https://www.npmjs.com/package/chrome-nfc) but I would rather create an app that doesn't require another app (Chrome) in order to be launch or used.

Any information would be highly appreciated.

NFC Interactor on Windows Phone 8.1 seems to support write-protection. Can I use this library to do that in my app? How?

Create and include a full demo app with Apache Cordova that shows how to use the JavaScript library.

I'm using this library for a Xamarin Forms project that supports iOS, Android, and UWP. I am using CoreNFC on iOS to read an NDEF tag. CoreNFC only gives me the bytes of an individual record.

For this library, I only see the ability to create an NDefMessage from a byte array and then loop through that to get the payloads. I have a record payload in byte form but don't see a way to init just a single record to get it's contents.

How can I get the contents from a NDEF Record byte array?

I tried to deploy project NdefDemoJS on Nokia Lumia 735. Unfortunatelly I got an error:

It's quite confusing cause I'm not sure where is a problem. I'm looking for any help!

Hi,

I want to proctect my data written in NFC chip by my password. So that the data will be read-only and not writale unless I unlock the password in my NFC chip.
I have checked using an app downloaded from Google Play Store that my NFC chip have feature to do a password protection.

I want to build an application to have password protection like that but I cannot find any function in NdefLibrary that support to do a password protection.
I'm using NdefLibrary version 3.1.1 and .NET framework 4.5.

Is there any way to use this lib in background task? I want to implement custom actions even if my app based on ndef-nfc is turn off.

Thanks!

Hi,
Sorry, I'm new to this NFC things, and I didn't understand the difference between NDEF and NDEF:WriteTag. I saw something about Static Tags, but I don't even know the difference between the normal tags!
Could anyone please help me??
Thank you,
Gabriel

Was just reading through code when I met a bad condition check. I think there should be || operator instead.

@ https://github.com/andijakl/ndef-nfc/blob/master/NdefLibrary/NdefLibrary/Ndef/NdefMessage.cs#L251

if (!seenMessageBegin && !seenMessageEnd) 
{ 
    throw new NdefException(NdefExceptionMessages.ExMessageNoBeginOrEnd); 
} 

Are you aware of any other platforms (beside the Windows Proximity API) this package can be used with? I currently have an SCL3711 NFC reader/writer. This does not support the Windows Proximity API, but can be used over PC/SC.
I found this repo and it is able to communicate to the reader, and it would be great to use the easily understandable classes in this repository. Abstract away any NDEF complexity for the programmer.

Hello!
Can I use Nuget https://www.nuget.org/packages/NdefLibrary package in my proprietary software project and to not open all project code?
I maked some research on this issue and found this post: https://github.com/dotnet/roslyn/issues/162

C# today supports dynamic linking, such that one assembly can reference another and with the latter being available to the former at run time, loaded at run time to be used by the former, etc.

Is it rigth what I can use this Nuget package in my project without project code sharing?
Thanks a lot!

The current demo apps are for Windows 8.1 (WinRT) and Windows Phone 8.0.
For completeness, also create a Universal App as a demo (which is pretty much the same as the Windows 8.1 demo app).

I can not install vs-mda or vs-mda-target which is neccessary to open JSdemo project. Please help!

I would like how to do this because in your sample you are using NavigationService wich is not availabel in Windows Phone 8.1

Any chance of a Xamarin Forms demo (UWP/Android - NET Standard)?
Thanks
Paul.

In the NdefLibrary.csproj, add a target to the .net framework 4.6.1.

<PropertyGroup> <TargetFrameworks>netstandard1.4;net461</TargetFrameworks>
By reference to this link (https://docs.microsoft.com/fr-fr/dotnet/standard/net-standard#net-platforms-support) netstandard 1.4 is compatible with net framework 4.6.1

This modification will be useful when using the NdefLibrary package in a .net framework project, so the application would not have to reference the .NETStandard.Library.

The current library includes all classes to read & write tags that initiate a connection handover. New releases could add the remaining handover classes that allow peer-to-peer handover scenarios, which would require the Handover Request NDEF record.

I clonedthe project to try out the demo, but I realize that NdefLibraryExtension in nuget is not compatible with UWP yet. So I try to build to lib, but cant not because of antlr.runtime.dll missing.
I cant get the demo to work.

Currently, the NDEF library fully supports Bluetooth services according to the latest specifications. In the future, the library will also add additional Bluetooth LE services.

Since that in NuGet doesn't exist the version 4.2.0 for NdefLibray and NdefLibraryExtension, I propose to change

and

to
Version>4.1.0</Version>
