The data flows depend on the acquirer capabilities and mandatory data flows, almost all of which is automated in some cases and not others. Chargebacks are frequently automated while disputes may or may not be. The local standards for accepting a dispute may be cumbersome and require paper even though the acquirer is fully capable of an automated process. Such is the case for at least two major Singapore acquirers. I do not know about others.
First, let's not bring ATMs to this.
Let's just focus on what I believe my DCC rights are:
- the requirement for my checking a tick box in a card-present situation

(with exception for Europe merchants

- the requirement for my express permission to apply DCC in a service agreement

Your chargeback (if that can be segregated from dispute) mechanism may deal with 99% of errors. Those we don't even know about as consumers. I'm sure they are important in such a mass scale, multi-party system and we've been relieved of a lot of processing errors.
What we're dealing with are disputes about how we are charged. Take your SGD20 transaction - the customer ticks SGD20 but the system is hard-wired to select the cardholder's currency (USD). The Singapore merchant and acquirer send out all the necessary and correct signals to indicate cardholder agreed to USD15.80. The card is present, valid, has enough credit and a proper auth code is obtained. But the cardholder ticked SGD20. How can you "automate" this dispute?
