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.
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.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
