Sales in NXP Semiconductor’s emerging ID business, which mainly includes its NFC chips, soared in the fourth quarter, growing by more than 200%, compared with the same period a year earlier, thanks mainly to the roll out of Apple Pay.

The Netherlands-based chip maker, which held a conference call today following release of its fourth quarter and year-end financial results late yesterday, is supplying NFC controllers and secure elements for all iPhone 6 and iPhone 6 Plus, along with the forthcoming Apple Watch.

The chip maker said Q4 emerging ID revenue also grew by 40% from the already high-level of sales in the third quarter of 2014, in which NXP recorded its first major shipments of NFC chips to Apple. Third quarter sales grew by 160%, compared with the same period a year earlier.
