Yesterday, PayPal relaunched Send Money, a Facebook app that allows payments, accompanied by e-cards, to be sent to friends. PayPal says 80% of its active users also use Facebook. 

The process begins inside Facebook where the app is launched and the recipient is chosen from the friends list. Then users select an e-card image, add a personal greeting, and type in the amount of the payment. The final step takes users into their PayPal account, where they login with their PayPal username/password, to confirm the transaction. Recipients need a PayPal account to redeem the cash. 

While the e-cards and P2P payments are free, PayPal’s international fees still apply.
