Unlike Venmo, which bombards the user with a text, email, and phone notification for an incoming request—you can complete the charge outside the Venmo app if you text back—PayPal.me caters to slightly more mature users by having them directly send the request themselves from their own email or phone number.
It also requires the person completing the link to remember the nature and amount of the debt in question, though a person could request a specific amount by sharing a link with a number at the end, separated by a slash. “Paypal.me/barackobama/25” for example. But the link isn’t specific to the person, and the service doesn’t even know if a request has been sent. A person’s PayPal.me address is nothing more than a dropbox.
