Hi Kan,

Ok, From the hardware side there is no limitation for extended APDU feature.

But in the user manual - UM10913, it mentioned that it supports the feature in T=1 protocol and not T=0 protocol.

And we can transfer the 255 bytes of data to cards in T=1 protocol for the contact card.

So, Can you please me such guidance for developing such feature.

Warm Regards

Sachin

Below is the screen shot from the user manual.

Hi Sachin,

There is no specific extended APDU guide available, it is just a message format, you may refer to the spec of ISO7618-4 for details.

Have a great day,
Kan

Hi Sachin,

There is no limitation on hardware to support this feature, but our NFC reader library has not added this feature yet, you have to implement this by yourself.

Have a great day,
Kan
