I really enjoy your videos and I have learned a lot about cards.
I am very interested in knowing how payment processing works in the case where the currency associated with the card differs from the currency in which the merchant receive the payments.
I am also interested in knowing how refund processing works: when the currency of the merchant and the issuer of the payment match and when a currency exchange must be made.
I really will appreciat if you can explain.

What exactly acquirer will do and what exactly issuer will do?

[y.c.breddy]

Where we can find transaction details like transaction code or transaction extra log, transaction history which is the best answer

[AG-wqmy]

You missed HSM & Keys component. Please add it in tech flow and explain. Thanks

Good information, but small correction
POS will not create ISO8583
Acquirer bank will create ISO8583
Correct me if I'm wrong..
Good article Sir👏👏
