Security chip specialist Inside Secure's mobile NFC division recorded sales of US$9.5m during Q2 2013, double its sales during the first quarter of the year, according to the company's latest financial results.

"As expected, revenue was driven by further deliveries to BlackBerry and its subcontractors, which remain the group's main customers in this segment as of today," reports Inside.

"The group delivered its first volumes of NFC microcontrollers within the Intel ecosystem (Ultrabooks and laptops). It continued to make good progress with the development programme as part of its contract with Intel and released the first version of next-generation NFC controller IP to Intel."

The company is now also sampling its ComboPulse product, which combines a secure element and an active modulation NFC interface, "allowing very small footprint integration."
