Mobile Wallet

Two kinds of mobile wallet running into our country.

They are :

Mobile Web Payments (WAP)

Mobile Money Transfer.

Problem Domain

WAP: Need BTRC Short Code.

Need permission from various government agencies.

Quite expensive for small merchandiser who manage small online shop.

Mobile Money Transfer: Easy to adopt but not suitable for managing online shop.

Manual process.

Problem Domain

Mobile Money Transfer:

Money has been sent

6

Problem Domain

Customer have to call customer care for confirmation about payment :

Customer Customer Care

7

Problem Domain

Totally manual process.

Customer have to wait for confirmation from other end.

Unable to provide real time support to customer.

Manage such customer care is not so easy for small online shop.

8

Problem Domain

Unable to handle high traffic.

Minimum synchronization time is 10 minute.

Sometimes customer have to wait 3 to 4 hours for payment confirmation.

So that small online shops unable to manage that kinds of process.
