Thanks to Iceman, now his fork can be build with EMV support even on 256k device:
Nonvolatile Program Memory Size: 256K bytes. Used: 222420 bytes (85%). Free: 39724 bytes (15%).
Transaction goes well
pm3 --> hf emv trans
#db# SELECT AID COMPLETED
#db# EMV TRANSACTION FINISHED
pm3 --> hf 14a list
Recorded Activity (TraceLen = 211 bytes)
Start = Start of Start Bit, End = End of last modulation. Src = Source of Transfer

But unfortunately dumping EMV tag values is not working, seems that some code adjustments required as the array of card data is not filled in:
pm3 --> hf emv dump
#db# currentcard->ATQA=
#db# 00 00
#db# currentcard->UID=
#db# currentcard->SAK1=
#db# 00
#db# currentcard->SAK2=
#db# 00
#db# currentcard->ATS=
#db# currentcard->tag_4F=
....
As an outcome of some investigations, EMV cards can also provide transaction history, that's might be an interesting stuff to implement as well.

I've created a new category and moved it there.

Came across an interesting C implementation for EMV - emv-tools is a set of tools to handle EMV (Europay, MasterCard, Visa) chip cards. Tools are based on the EMV v4.3 standard.
The code can be found here: https://github.com/lumag/emv-tools/
I may assume that this handling should also apply for NFC way of communication.

The AID and commands should be similar. In Peter Fillmores imp, its placed on device side. We should move it over to the client. That will free a lot of space on device again.

My mastercard is ISO14b, so the hf emv * doesnt work. The current imp is using 14a.
I also needed a strong HF antenna to power/read card.

I've made a clip showing how to enable EMV on my docker container

Coverity Scan found some bugs inside EMV source, I've pushed some fixes. @osys, would you mind testing?

The new EMV command implemented by Merlokk in PM3 Offical should be helpful
