You can read online. I would tell you what I read few days back. Sada pay is an online payment system as PayPal and other services don't come to Pakistan.
Now Sada pay is sanctioned by state bank of Pakistan, it is developed by an American and locals, they are aiming to reach it to 3 carore people by the end of 3 years. This card doesn't need any bank account. You simply have to fill some easy details and get a card. You can pay your bills, transfer money, and carry cash and pay through your mobile. So it's you mobile wallet.
One thing that is different is that you can receive money you earn as a freelance worker or people giving other services who do not have a source to get their money directly. They can receive their money from 40 countries including us, gulf and eurpeon ones.
So all those working online would easily get their incomes directly transferred into their mobile wallets.
You can pay your daily task easily with card or with your mobile.
Sadapay has connection with western union and other money share companies such as PayPal that allows them easy money transfer. This is a huge step for paksitan. As people are dying to get PayPal and they are not coming. This would be the next best thing.
