We should point out that Western Union has long supported Apple Pay, but that’s only if you visited a brick-and-mortar store. However with this update, the money transfer service will now bring in-app support for Apple Pay. As to what the difference might be, we guess in a way it is faster since Apple Pay just requires users to verify themselves via fingerprint, assuming of course all your payment information is already on file.
This is versus having to manually enter your information, but at the end of the day it is simply an alternative to a fully functioning money transfer service, so at the end of the day it’s really up to you which service you prefer, or which you find more convenient. That being said, the in-app support for Apple Pay will only be available to those living in the US for now, but it is expected to expand to the UK later this year.
