Tyfone received two U.S. patents covering technology that can be used for mobile payments, the company said May 21.

The technology allows a near-field communication antenna to function from a MicroSD memory card, which can be used with many smartphones. Tyfone offers such a card, which it calls SideTap.

"Since 2004, Tyfone along with its partners has been defining and developing a wide range of technology innovations to enable mobile commerce," said Prabhakar Tadepalli, chief operating officer of Tyfone, in a press release. "Part of the payoff of our hard work is delivering these patented products to market and overcoming scaling challenges, eliminating the last barrier to global NFC implementation."
