The disruption has to come from bypassing credit card companies like Visa and Mastercard.
In India, almost every merchant is using UPI which saves them fees of credit card processing.
The world banking is getting more advanced and technical and I am sure payment gateways can bypass the credit card and currency conversion fees with direct bank to bank transfer.
For larger Amount, we are asking our customers to use Wise instead of stripe or PayPal as the saving for us is significant.
