The customer owes money to a friend or wishes to transfer money to someone. In this situation there are three options available. If the two parties are in the proximity of each other the payee's device sends the transaction data over to the payer's handset using either IrDA, BT, or RFID communication. If the two parties are not in the position of using a direct link, the payee can send the necessary information over the air (SMS, IM) to the other party. In certain cases the payer initiates a transfer while the payee may not even be aware of the fact that he or she is going to receive money. In this case the payer can manually input all necessary information into the handset. Depending on the transaction value the payer in all three cases has the option to select either its bank or MNO for processing the payment. The payee will receive the payment notice on its mobile handset in real time.

A merchant may not have a regular POS terminal either because of the cost implications, or the type of services offered, or because of the mobility of the operation. (e.g. taxi driver). With the mobile merchant module in the handset of the seller, the merchant is capable of providing the necessary payment information to the customer. The customer initiates the payment through its bank or mobile operator and the merchant receives the payment notice onto the mobile device. As this payment notice serves as a payment guarantee of the merchant's bank, the products and services can be provided risk free to the customer real time. Optionally it is also possible to digitally sign the original payment information, in which case the message from the merchant to the customer serves as a legally acceptable invoice.
