NFC: NTAG 424 DNA TT authentication - application tips needed

Asked 2022-Jan-30 at 07:06

I've these chips NXP NTAG 424 DNA TT. I've set them up (SUN + mirroring) using Android app NFC TagWriter by NXP. I am missing one crucial detail. Some operations, like loading an application key into the chip, require the writer to authenticate. I haven't found an app which is able to perform these actions which need authorized writer. Any tips for an (Android) app which I can use to change the application keys?

Unfortunately this is a Type 4 NFC Card, while it is configured with the Industry standard Application ID (AID) for Ndef data storage initially, there is so much more non standard stuff if can do that unless somebody has written a specific application to do all the stuff then it it unlikely for you to do what you want.

You will probably have to write the Android Application yourself to issues the specific commands you want via IsoDep API

You cannot call doWork() directly from the main thread because in that case it would be called in the main thread which would be blocked then. Exactly as you observe now.

So the correct way you trigger the worker to do the work in a secondary thread is this connection:

Read information from Bluetooth NFC reader

Asked 2021-Nov-26 at 20:06

I'm trying to make an Android app (Java) that reads the information from an "NFC to Bluetooth reader" (like this one).

Basically, the device will read the information from the NFC and transfer it to Bluetooth.

I'm trying to make an app that reads the information from that device via Bluetooth, but I haven't found any solution.

Is there any link or keyword that could help?

...

ANSWER

Answered 2021-Nov-26 at 20:06

Usually, these Bluetooth readers come with a library. The product you provided sells some development tools that would probably help you integrate it into your application. Though very costly.

I found a github repository, which provides a library to connect to NFC Readers via USB. Bluetooth connections are supported as Beta for exactly your linked product. So, I think the repository is a good starting point for you.

I personally worked with these readers, where a fully functional library was provided. I can 100% recommend them, however I think they were pretty costly.

EDIT: I looked again on the website of your product and they provide some downloads. Two of the downloads are for their sample Android application, which includes the application's source code as well as their library. So, if you got that product simply download their resources and integrate the parts you want in your applcation.

In which cases normalize('NFKC') method work?

Asked 2021-Nov-09 at 16:57

I tried to use normalize('NFKC') method with different characters, but it didn't work. Fortunately, can't say this for NFC. When it's possible normalize('NFC') always replaces multiple codepoints with the single one. For example:

ANSWER

Answered 2021-Nov-09 at 16:57

The thing is NFKC (as well as NFKD) supports compatible and canonically equivalent normalization.

Unicode

The type of full decomposition chosen depends on which Unicode Normalization Form is involved. For NFC or NFD, one does a full canonical decomposition, which makes use of only canonical Decomposition_Mapping values. For NFKC or NFKD, one does a full compatibility decomposition, which makes use of canonical and compatibility Decomposition_Mapping values.

And that's completely understandable because as MDN says:

All canonically equivalent sequences are also compatible, but not vice versa.

But it's also worth to notice that NFKC makes compatible and canonically equivalent normalizations in different ways. Canonically equivalent normalization by NFKC is produced the same way as NFC. For example:

Found an appropriate solution: You can use the uconv utility from ICU. Normalization is achieved through transliteration (-x).

On Debian, Ubuntu and other derivatives, uconv is in the libicu-dev package. On Fedora, Red Hat and other derivatives, and in BSD ports, it's in the icu package.
