Thanks Peter! Indeed, let's clarify: the part, the electronic IC / component from STMicro is priced wherever it is.
Our comment aimed at dispelling the belief that $0.72 for an IC means $0.72 for a finished good, commonly known as a temperature logger / temperature recorder (vastly different from just a sensor).
We had very frequently seen a lot of hype / hope on the RFID front for super cheap temperature loggers and pies in the sky.
We are just presenting two pieces of the same pie: NFC+RFID is arriving to a smart phone near you soon and it's going to revolutionize the cold chain. But it won't be free and if 1000 units is $0.72 per IC, another common misconception is to think that 100,000 means $0.22; 1,000,000 means $0.12 and 5,000,000 means STMicro can afford to give it away for free!! :)
We are just keeping things real!
Regardless, it's exciting for the cold chain and the NFC technology.
What's to clarify?
I'll write it again
If you order 1000 of the component M24LR64, a dual-port EEPROM, the price is $0.72 per IC.
Evidencia is talking about a completely different item, an NFC temperature recorder, which he reckons will cost at least $30.
These two pieces of information can both be true.
Dear Luis, and all: as working for the only company releasing a fully commercial version of an NFC temperature recorder (and thermometer), I want to dispel the belief (and lie) that plagued the RFID sensing business after the DoD and WMT hypes -- a true temperature recorder, passive or not, functional, with all elements, plus sales and marketing and R&D and SG&A and expected income will cost in the $30's to start -- bare bone and for real life quantities (100 to 1000 units per customer). $0.72 is the board only... add everything else (parts, wraps, salaries, expenses, cost of time for R&D) and again, the real volumes, and please realize than these "even cheaper to come soon" are either vaporware, lies or probably 5 to 10 years down the road.
Super cheap RFID sensors existed, but never converted to super cheap finished products.
Stay real! :)
Come on guys, we are talking about NFC. These are to become like tags. They have to be cheap if they are to work as intended.
Each NFC enabled device is merely an antenna and a spot of sillicon. The fact that NFC tags are passive means they donīt need power supply and thus a fewer parts count. I think we can expect even cheaper devices to come soon. Be aware!
