POS Subsystem is split into reader, kernel and entry point. Download from EMVCo website the complete specification and understant what is expected from entrypoint and kernel perspectices. There are 9 in total
- architecture(1)
- Entry Point specification(1)
- Kernel specification for each( 7, one for each payment scheme ).
Go through 1, 2 and the relavant kernel spec from third.
You can find values of TTQ here. https://emv.cool/2020/12/24/Terminal-Transaction-Qualifiers-TTQ-9F66-qPBOC/
It's only VISA tag as far as I know.
