One of the key motivation to design a social payment system was observing the recent people behaviour of trying to selling items through their Facebook pages. Normally they publish a post with a picture of the item and its price. Then a discussion will go along in the comments section. If a friend want to buy this item he has to ask the first person to either send his account detail or meet somewhere etc. The use of Quidlink will make this task easy since once the persons decides to buy the item all what he have to do is to click the link which takes him to the payment screen. Then the seller will be notified of the execution of transaction and will be given the details of the person purchased it to communicate with.
