If we were to apply the same principle to mobile payments we start running into a number of problems. This is because many mobile payment solutions work in a different way than what credit card transactions would work in general. Some of the challenges that one will have to consider are:
- In many cases, it is the payer that pays for the mobile payment transaction fee. (Consider for instance money remittance case study)
- The management of exchange rates for different currencies are dealt with in many different ways. Supporting this in a clear interchange fee will be difficult.
- Interchange fees often also caters for a credit component. Mobile payments are usually based on positive balance value stores.
- The willingness of both parties to pay for transactions (to send and receive money) is different in the mobile payment dispensations.
