The optimal way for Curve to implement a DCC block would be a simple setting within the Curve app with three options:
Dynamic Currency Conversion
- Allow all GBP transactions
- Block GBP transactions where underlying funding card’s currency is not GBP
- Block all GBP transactions
Most people would leave it on the middle option most of the time. Typically non-UK residents will switch to the first option when spending in the UK, and UK residents will switch to the third option when spending outside the UK with a GBP-denominated underlying card.
@Curve_Marie, can this be implemented please?
It could later become more complex and perhaps identify the country of the merchant, with a fourth option to block GBP transactions by any merchants not in the UK, Channel Islands, Isle of Man, Gibraltar, Falkland Islands, St Helena etc, but this is probably too complex for a first implementation of DCC blocking.
