Interesting. But aren't the banks responsible for handling chargebacks and fraud, not the credit card processing companies?

My (albeit limited) understanding is that Visa and Mastercard ensure that the debit/credit transactions are securely and quickly occur, but if there are post-transaction issues like fraud or chargeback, then the credit card-issuing bank handles/resolves those issues.

Conversely there's probably a subset of transactions that don't need this sort of "insurance", such as buying groceries. Currently the merchant still has to pay the 2%+ fee in the U.S. but would be nice to have the option for a customer to waive the "insurance" part and benefit from a 2% savings. It's akin to many merchants offering a lower "cash-only" rate.

Now in the EU, if online transactions are over a certain amount or flag up as suspicious, we must use 2FA. So I have to stick my card in my card reader and generate an OTP. Works quite well tbh. My other bank sends me a push notification where I approve the payment.
