2011/09/30 NFC不再有價值?
- Sep 30 Fri 2011 11:44
2011/09/30 六大手機製造商ISIS NFC支付
Isis, a joint venture between U.S. mobile phone service providers AT&T Mobility, T-Mobile USA and Verizon Wireless, has announced that HTC, LG, Motorola Mobility, RIM, Samsung Mobile and Sony Ericsson will introduce NFC-enabled mobile devices that implement Isis NFC and technology standards for electronic payment.
Isis is working with DeviceFidelity Inc. (Richardson, Texas) to standardize the addition of NFC functionality to cell phones to turn them into electronic wallets, which DeviceFidelity does using a micro-SD card technology.
However, no dates were given for when the phones would be in the market, or when Isis NFC payments would become commonly available, or whether Isis NFC would be deployed outside the United States. Pilot deployments are expected in 2012.
NFC-enabled phones are expected to allow consumers to make payments, store and present loyalty cards and redeem offers at participating merchants with the tap of their phones. However, the industry has been slow to implement the technology as different groups – particularly credit card companies and cell phone service providers – have maneuvered for control of systems in deployment and lobbied for support and critical mass.
"Isis technology standards provide the direction and certainty needed for the development and deployment of NFC devices and the mobile commerce ecosystem," said Scott Mulloy, chief technology officer at Isis, in a statement.
"NFC is the future of mobile payments and will ensure that transactions are done securely from mobile devices," said Christy Wyatt, corporate vice president of software and services product management at Motorola Mobility, in a statement issued by Isis. "Through working with Isis as well as the broader Android ecosystem, we look forward to providing consumers with NFC-enabled handsets that make mobile commerce a reality."

Switched On: No new wires, one new caveat
In the decade that WiFi has blanketed home networks across the United States, several technologies aimed at using existing wiring in the home have met with limited success. These have included MoCA (Multimedia over Coax, which has been adopted by some service providers for implementing multi-room DVRs) and HomePNA (originally for phone lines but later expanded to coax cable as well). At least three dueling standards have also sought to bring high-speed connectivity over electrical wiring. HomePlug, the most successful of these, has had several iterations. The latest – HomePlug AV – is rated at a theoretical throughput of 200 Mbits/sec. However, power line technologies have been held back by high prices and occasional interoperability problems.
