    The direct mobile billing model is useful mostly in the electronic commerce site where the 
consumer uses the mobile billing option to make payments for services like purchasing songs 
and software. The authentication process is a two-factor one with one requiring the personal 
identification number (PIN) and the other a one-time password to discourage unauthorized

does not require credit cards or even prior registration with an online payment solution like the 
Paypal method making it more preferable than banks or even the credit card companies due to its

factor check out processes. The two merits have enabled the service to be very common 
worldwide with 70% of digital contents being purchased online (Jack, 2010). 
    The mobile web payment model uses the cell phone downloaded and installed applications. 
The model also uses the wireless application protocol (WAP) as the supporting technology. The 
method, however, must also use the debit or credit card to finish the process although it is a 
faster and more convenient method as compared to the other models. The direct operator billing 
model, on the other hand, has prerequisite network operator integration. The method is however 
very convenient and secure thus making it very accessible.

phone via is or her telecommunication service provider. After that, the customer can comfortably
