Canada-based Kili Technology, which supplies hardware modules, firmware and IP for mobile point of sale, readers and other payment-acceptance devices, has acquired NFC-accessories vendor DeviceFidelity.

DeviceFidelity now becomes a wholly-owned subsidiary of Kili. The parties did not disclose the price paid for DeviceFidelity, an eight-year-old Texas-based company, which has failed to see any major deployments of its products, outside of perhaps iPhone cases for the mobile carriers in the Softcard joint venture, formerly known as Isis. But take-up of these devices is believed to be small.

DeviceFidelity designed and supplied cases for previous versions of the iPhone and also microSDs that could be used for cases. And it designed and supplied microSDs embedded with their own tiny contactless antennas for use in Android and BlackBerry handsets. The latest version of this product uses an amplifier chip from Austria-based ams AG. A later version of the chip is used in the iPhone 6 and 6 Plus.
