Siri integration has been live in the app for a few days now, and is meant for smaller payments like your share of the dinner bill, with single transfer and daily limits to keep spending in check. Barclays boasts it's the first UK high street bank to enable Siri payments. That's technically true, though PayPal added the feature towards the end of last year and Santander added voice payments to its app in February, though it's not Siri you're asking in that instance. Siri's able to take on new tasks such as making payments thanks to Apple finally allowing other apps to talk to the assistant from last summer. And given what Google said earlier this year, its voice assistant isn't too far from acquiring a similar skillset.
