Tweakers.net had a post linking to this EETimes.com article that outlines that SanDisk and Philips join forces on cell phone payment:
Flash memory card supplier SanDisk Corp. has struck a deal with Philips Semiconductors to embed the Philips SmartMX smartcard controller chip in certain types of flash memory cards to allow them to be used for near-field communications (NFC) and in particular, when the cards are inserted in mobile phones, to pay for things.
SanDisk (Sunnyvale, Calif.) said the SmartMX would be embedded in TrustedFlash cards allowing consumers to use their phones as bus or train tickets and perform secure “contactless” payments and other contactless transactions by simply waving their phones near a contactless reader in a mass transit turnstile, checkout counters or drive-through windows.
TrustedFlash cards with SmartMX technology for NFC transactions are available to OEM customers in the microSD card format. SanDisk has started pilot programs and expects broader commercial rollout in 2007. The company did not state where the pilot programs are being run.
