NXP Semiconductors reported lower revenue from its NFC business in the second quarter compared with the first quarter, as the loss of a key customer, Samsung Electronics, begins to bite.

And NXP CEO Richard Clemmer, while saying demand for NXP’s NFC chips was still strong, predicted that NFC revenue would be flat in 2013, compared with 2012, because of what he called the “product transition at one of our major customers,” a reference to Samsung.

As NFC Times first reported in March, for its new flagship Galaxy S4, Samsung chose a chip from U.S.-based Broadcom over the NFC controller NXP had been shipping to the device maker for the Galaxy S III and a range of other Android phones.
