DESFire EV3 NDA eSign request never delivered

MIFARE DESFire EV3 NDA approved but Adobe Sign request never delivered – support refuses to escalate to NXP Contracts (case 00996763)

Hello,

I am looking for someone at NXP who can help me finish an NDA process that is stuck for purely technical reasons on NXP's side.

Background:

I am a software developer in the Czech Republic building a mobile POS application (Android/iOS) with a closed-loop NFC payment extension based on MIFARE DESFire EV3 (MF3DHx3). I need the confidential EV3 documentation (full data sheet / command set, secure messaging, key management) from DocStore.

On 1 August 2026 I submitted an NDA request through the NXP online process (support case #00996763).

Between 1 and 7 August I provided everything NXP compliance asked for: company website, official trade register document, ownership structure, detailed project description, volumes, design stage, end use.

On 12 August NXP Technical Support confirmed the NDA was approved and sent via NXP Contracts / Adobe Acrobat Sign to my signatory e-mail. On 18 August they confirmed a second eSign request.

The problem:
Neither Adobe Sign request ever arrived. Not in the inbox, not in junk, not in my Adobe Sign account, and – most importantly – there is no trace of any delivery attempt from adobesign.com / echosign.com in the Microsoft 365 Exchange message trace for the whole period. The transaction fails before it reaches my mail server.

Technical Support says that "for security reasons we cannot resend the file", that they "cannot verify my e-mail address further", and that I should start over through an authorised distributor. A request to simply forward the case to NXP Contracts so they can check the Adobe Sign transaction and issue a new agreement (or send the NDA as a PDF for a handwritten signature) has not been actioned.

The e-mail address in question is my only business address on my own domain and has been working for all other correspondence in this case, including all e-mails from tech.support@nxp.com.

What I am asking for:

Could someone from NXP Contracts, the MIFARE product team, or anyone with access to the Adobe Sign audit trail please look at case #00996763 and either re-issue the eSign request or provide the NDA in another form? The due-diligence review is complete and approved – the only missing step is delivering one document.

Any pointer to the right contact would be greatly appreciated. Thank you.

Hello @clexpert

Hope you are doing well.

Please accept my apologies, this is not the proper path to address any NDA topic. All the processes are handled by our Legal team after issuing the NDA online form.

For further information about the status of your process, please continue the communication in your NDA ticket.

Regards,
Eduardo.

Hello Eduardo,

thank you for the reply. I understand, and I would be glad to continue in the NDA ticket — the problem is that the ticket is effectively closed:
Technical Support has twice answered that they "cannot proceed online" and that I should start over through a distributor, and my request to forward the case to the Legal / Contracts team has not been actioned.

So my only ask is this: could you please pass case number 00996763 to the Legal team internally, so that someone who can see the Adobe Sign transaction looks at it? The NDA was approved on 12 August; the eSign request just never reached me (no delivery attempt in my mail server trace at all). A re-issued eSign request, or the NDA as a PDF for a handwritten signature, would resolve it immediately.

I will add a note to the ticket referencing this thread. Thank you.

Petr

Hello Eduardo,

thank you again. Following your advice I continued in the NDA ticket (case 00996763) and explicitly asked for the case to be forwarded to the Legal / Contracts team, as you mentioned they handle these.

The only reply I received today was, for the third time, a one-line message: "please contact NXP distributor for NDA creation." No forwarding to Legal, no comment on the failed Adobe Sign delivery, no reference to the audit trail I asked about.

To summarise where this stands after three weeks:
- The NDA was reviewed, approved and issued on 12 August.
- Two Adobe Sign requests never reached my mail server (confirmed by a full message trace - no delivery attempt at all).
- Technical Support cannot re-issue it and will only repeat the distributor advice.
- I have contacted authorised distributors in parallel and am waiting.

Could you please make the internal hand-off to Legal / Contracts yourself, or give me a direct contact there? I would simply like the already-approved NDA to be delivered - by a re-issued eSign request or as a PDF for a handwritten signature. I am keeping the tone constructive; I just need this to reach someone who can act on it.

Thank you.
Petr
