Merchants are clearly defined in card payment terminology. A merchant is someone that accepts a card from a client and then initiate a payment request/authorisation. A merchant usually have a relationship with a specific bank (called an acquiring bank) and should have secure infrastructure (terminals) that can accept a card and initiate the authorisation transaction. This model is proven and tested and works well in many markets. Trillions of dollars are processed in this way and these merchants form the foundation of retail economies of the world.However, in many emerging markets, large volumes of transactions are processed (usually in cash) by retailers looking very different and operating within a very different economic model. These traders often do not do business in permanent structures and work irregular hours and with much more flexible business models. These merchants generally cannot afford terminals, do not have connectivity, nor have reliable electricity available. The needs for reconciliation and cashier management are also significantly different for these retailers.
It is inconceivable that these merchants be served in a model that does not consist of the four parties (as is the case with interoperable, open card payment models). However, digital payment models for this sector (most likely based on mobile phones), will have to be designed with very different liability structures, different fees and less overhead. At the same time, these solutions would also offer less utility and features compared to the established schemes.
The time is ripe for the development and prototyping of these type of payment solutions.
