NFC is faster than Bluetooh hence suitable for transfering large data in lesser time. However bluetooth's RF cloud is relatively large hence convinient. I am curious if someone can compare NFC with traditional IR port interms of speed and power consumption.

This is especially good, considering how iffy the credit card magnetic strip readers can get. It would be great to use NFC instead of the antedeluvian magnetic strip!

I would think that the comparison SHOULD be between NFC and optical bar codes, not Bluetooth. Bluetooth is more of a "personal area network," and it works wonders, for example, to connect your cell phone to your car's hands-free cell phone system. Sylvie, I use NFC daily, to get in and out of the Wash DC metro system and metro parking, and also to get in and out of my office (electronic gates and doors). Imagine how neat it would be if I could use the same card I use to get into the Metro system also for, say, food shopping.

Just checked: my mistake--Sprint went with Google Wallet instead of Isis. I wonder if this will be like their WiMax vs LTE mistake of being first with the technology, but ending up with an orphan system.

Well, when Isis comes out (launch date, Oct 22, today!), then there will be a payment system supported by all the major US credit cards and telcos, along with standard NFC payment equipment for stores. When stores start installing NFC payment systems, and customers see how quickly and easily other customers can make payments using NFC, I think you'll see its use spreading pretty quickly.

It feels like the industry has been harping on about NFC for years and years, and yet.... where are all those swarms of people using it? Nowhere. NFC holds much promise but has so far delivered very little.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
