I understand that Near Field Communication technology can be used in a cell-phone handset, or as a standalone chip that can be attached to the back of a cell phone, enabling users to make payments. Is this correct? In addition, Hong Kong's Octopus mass-transit card is a contactless automated fare-collection (AFC) system combining radio frequency identification with technology from Vix ERG, of Australia. Are there any RFID AFC systems available in solutions similar to or better than those provided by Vix ERG?
I reached out to NXP Semiconductors, a provider of NFC technologies, to answer your first question. NXP informs me that it is possible to develop a SIM [subscriber identity module] card with NFC capabilities. Gemalto offers a SIM card with NFC capabilities, known as DIF SIM, while Bladox, in the Czech Republic, also provides such a SIM card.
As far as Vix ERG goes, NXP notes that that company is just the system's installer, and not the manufacturer of the Octopus card, which is actually based on Sony's Felica transponder, utilizing the secure ISO 14443 air-interface protocol. All contactless fare-collection systems are RFID-based, and most are built on the fundamentals of the ISO 14443 protocol (though some utilize the ISO 15693 standard). Vix ERG has performed installations using NXP's Mifare transponders.
Yes, there are NFC stickers that you can place on a phone or some other object in order to turn it into an NFC-enabled device. The following articles discuss these stickers, and explain how they are used:
