My physical cards dont work. Possibly wrong setup when writing data onto the stripe??

[Ontour]

Hi together
I was trying to write some 101 dumps with my MCR200 and I am facing some issues. I’m writing the magnetic stripe only..
I was trying several different tools like Cardpeek, TheJerm, Exeba, MSRX & MAgstripcard reader/writer Utility. Most oft he tools did not work because some did not recognize my MCR200, Exeba and TheJerm recognized it but did not communicate properly and frooze.
Magstrip ist he only which is working fine and is the one i used here, however it seems to be very basic, there is not much to configure and reading as well as writing seems to be working fine.
When reading a card, i get the data exactly as it is shown below, meaning there is nothing like a start sentinel like „%“ but simply the naked string. So when writning my dump data i used the same format. I used:
Track1: B0XXXXXXXXXX69423^MAUER/STEFFEN^22071010000000000277689382573383000000
Track2: 0XXXXXXXXXXX69423=2207101277689382573
I was writing that onto my card and swiped it through a POS @ McDonnalds. The POS device said „read error“
I then went back home and added sentinel and stop sign like:
Track1: %B0XXXXXXXXXX69423^MAUER/STEFFEN^22071010000000000277689382573383000000?
Track2: ;0XXXXXXXXXXX69423=2207101277689382573?
Additionally i made a second card, similar to the above, including sentinels but i also substituted „=“ in track 2 with „‘ “
The sign `did not make much sense to me but i tried it because i have seen one of my cards showing track 2 like that after i was reading it, so i gave it a try.
Those 2 cards did not show „read error“ this time when swiped through the POS but they were showing something like „can not proceed“. POS and shop was a different model compared to the first one.
I cant see what i did wrong here, so i would be happy if someone could give me advice.
I hope my language was good enough to make you understand what i am trying to explain…
Thx and all the best,
