run APDU commands on NTag424 DNA

[shaghayeghnz]

Hello,

I am currently developing an application using Flutter to write to an NTAG424 DNA NFC tag; however, I am encountering some issues with the APDU commands. I am unable to execute a simple APDU command.

For instance, when I run the write command "908D000019010E0000120000FF0506E1050080828300000000000000000000," I receive a response of 0x919D.

Similarly, when I use the command "004300E0000100C1F1212000004300009100," the response I receive is 0x6700.

Additionally, I would like to know how to set keys for authentication.

p.s. I do not own any hardware/software NFC reader/writer (except for my flutter app).

Best regards.

Hi @shaghayeghnz,

Sorry for the inconvenience this might cause you, but as the information of this product is under NDA (Non-Disclosure Agreement), the information is not public, and this is not a secure channel to share any information of this device.

Please help me confirming you are sending the correct commands (information and length).

Unfortunately, I cannot deepen into much more details, but under "Documentation" in the NTAG 424's page, you can find its Datasheet, and in chapter 11.6 (Key management commands), you can find information on application keys.

Please help me looking into our Distributor Network to contact them so they can help you with further requests.

Best regards,
Julián.

Thank you for your response, @Julián_AragónM.

I would like to inquire whether, upon receiving an NDA (Non-Disclosure Agreement), I can develop my application independently without relying on your software/hardware NFC reader/writer. My intention is to create an application that is entirely self-contained and doesn't depend on any other software or hardware.

If the answer is affirmative, could you please provide information on how to obtain an NDA?

Best regards, Shaghayegh.

Hi @shaghayeghnz,

NDA only applies to disclosing non-public information. All NTAG 424's security features are under NDA, and you will need to contact one of our distributors from the Distributor Network I mentioned if you want further information or support. An NDA is not needed to develop your application.

Best regards,
Julián
