How do I allow and deny certain cards? #5

Hello once more! I was wondering if there was a way to deny certain cards on the terminal or allow them, e.g. don't allow the usage of American Express, Discovercards, Alipay, etc. or only allow Girocards, Visa and Mastercard, etc.?

Here is the documentation https://www.terminalhersteller.de/downloads/PA00P015_13.09_final_en.pdf

I took a look through that and saw the card ID's. In your library, you defined a bunch of card informations. If I remove the ones I don't want to be supported, will it abort the payment right away?

I rather think that you would have to define special cards via a TLV command here

I figured that. This was more of a regular question. Turns out that the provider for the terminal decides which cards are allowed and which are denied.
