Like the Barclaycard app, which has NFC payments since January, Contactless Mobile detects whether a customer's Android phone supports NFC and has eligible Barclays credit or debit cards associated with it. If it does, customers can make payments of up to £30 by tapping their phone against a retailer terminal, without needing to open the app, enter a PIN or verify with a fingerprint.
The platform will also support payments between £30 and £100, which involves first tapping the phone against the terminal, entering the card's usual PIN and then tapping again.
Barclays says that when Contactless Mobile arrives next month, the roll out will be "phased over a number of days." Customers will be notified as soon as the service becomes available. It could come before Google's own platform, as long as it's not as drawn out as the bank's Apple Pay implementation.
