Here's how its latest gifts product works: Users pick a friend they'd like to send a gift card and can select from a range of retailers, including Jamba Juice, Olive Garden, Sephora and Target. Once the card is purchased, the friend is instantly notified. A few days later, he or she receives the card in the mail.
The cards are reusable and can hold multiple balances from different retailers. For example, if you are gifted $20 to Jamba Juice and a week later a different friend gives you $50 to Sephora, the new balance automatically shows up on your card. Facebook users can view their balance through Facebook and can monitor balances with mobile notification.
