Snapchat users will soon have the option to send friends a few bucks via the vanishing messaging platform. Snapcash is a new function that resides within Snapchat, but uses a different service, Square, as a payment processor. To that end, Snapcash users quickly become Square users, as they’ll need to set-up a Square account to take advantage of Snapcash. Fortunately, there isn’t much to do aside from type. Snapchat recognizes that you’ve entered a dollar amount, and offers to let you actually send the cash along.
