US secure mobility solutions provider Tyfone has completed its SideTap micro secure digital (MicroSD) memory card versions and is set to make the new products available in the second half of 2010.

MicroSD memory cards enabled by Tyfone’s SideTap contactless payment technology with integrated 13.56MHz coil can be used by hundreds of millions of mobile phones at thousands of existing contactless payment terminals worldwide. These cards will work in phones with MicroSD slot on any side of the phone – top, left, right, bottom or back.

The SideTap memory card technology integrates near-field communications (NFC) contactless card payment capabilities with a commonly used mobile phone accessory, a MicroSD memory card. SideTap memory cards enable MIFARE as well as any Global Platform compliant payment applet.

The SideTap MicroSD card contains an onboard controller that manages over-the-air (OTA) capabilities allowing consumers to add multiple payment and identification options. Because the SideTap MicroSD card also retains all its memory card functions, consumers can also use them to store documents, photos, videos, music or other files.

Using SideTap memory cards, consumers purchase goods simply by tapping their mobile device at a point of sale reader. The read distance ranges from 1 to 3 cm depending on the reader and transaction speeds are identical to contactless plastic cards.
