Deploying these rules in emerging markets are difficult because of major differences in laws, subscriber behaviour and availability of infrastructure. What is needed is a fresh look at the rules that dictate global payment products. To re-think the rules and re-define them in the context of emerging markets.
The new Visa product (mobile pre-paid) (Read here) recently announced attempts to do just that. It is a fully fledged Visa product, but with a re-worked hand-book where the rules have been re-defined to cater for emerging markets. I would not like to comment on how well this has been done, as I am directly involved, but believe that it should be reported on in this blog.
