“Hey Siri, send what’s-his-face that money I owe him for that thing.” PayPal has introduced Siri support, letting users send and request money using voice commands on iOS. The new feature is available in 30 countries (see a list of supported markets here), and works just like you’d expect. Just access Siri in the normal way and say something like: "Hey Siri, send Bill $50 using PayPal." This isn’t the first time Siri has been used for transferring money though. Apple added support for this feature earlier this year, and vendors like Square Cash, Venmo, and Monzo (a UK bank) have already integrated it into their apps as well.
