NFC MicroSD Card and other OS's / Phones

[darcyja]

Is it possible to develop my own device drivers for the NFC MicroSD card?

- Is the T80 the only phone currently available?
- Are other Windows CE phones planned?
- Are other non-windows CE phones planned?
- Does the microsSD card come with its own API? That is, if I wanted to communicate with the card using other operating systems (nokia series 40, series 60, palm) could I write my own drivers to access the card, without using java?

I appreciate that you have created a J2ME with the appropriate JSR's implemented, but I am interested in lower level interfaces.

Kind regards

Hi darcyja, how are you?

We have not tried to develop our own drivers for these microSD, and the information of how they work is kept by BenQ.

BenQ is working on the T60, but this is a non-windows phone.

In our research of the BenQ, the port to access to the NFC chip is already locked by the JavaVM, and it is the only way to access to the secure element. This NFC chip has a driver which interface is provided by NXP.

I hope this information could clarify your questions.

Best regards,

Jose

Who made the microSD card? NXP, Benq or clear-idea? Surely they would be happy for people to write drivers for their devices.

The microSD cards are made by CellIdea. The secure element chip inside of it is made by NXP, and BenQ mades the contact to connect with the secure element, the two extra pins of these cards, which connect with the NFC chip inside of the BenQ.

Thanks you Jose. I was slow to realise that the NFC communication component was in the mobile phone, and not the microSD card itself.

That changes my approach. Kind regards
