Cheap SAM option with Mifare SDK for Android

[Dave Cleal]

Hi,

I read here (https://www.mifare.net/support/forum/topic/taplinx/) that

"The problem of supporting a SAM AV2 is the contact interface. Some phones has a separate SIM card slot, but the most don’t. If you use a contact reader connected via USB cable, you have to use the driver of the reader and every manufacturer provide its own driver. There is no standard interface for a SIM card on an Android system and this is the reason why you cannot support the SAM within from TapLinx on the phone."

I have three questions arising from that:

1. Does this mean that a phone with an extra SIM card slot will just work with the TapLinx SDK, or would extra work be required to write a driver to use a SAM in the SIM card slot?

2. Is there any USB reader that is supported by the TapLinx SDK out of the box?

3. Do you know of any open source efforts to fill this gap?

Regards

Hi Dave

1. No. The extra SIM slot is usually not available as public interface and is not supported for programming purposes. It is used only for telecom providers as second source.


2. No. It exists SIM card USB readers (e.g.: OMNIKEY 6121 USB Reader) and in very early releases of TapLinx this was an option. But you need always the manufacturer driver software for using this reader. The combination reader driver and TapLinx offers a bunch of possible issues. It is not supported by TapLinx.


3. No, sorry.

OK, so what does NXP recommend for an Android application where we want to scan DESFire cards and we want to keep the keys secure?

Hi Dave

We do not have an out-of-the-box solution for this case.

Sorry,
