RFID or Radio Frequency Identification
RFID, which responds to the initials of Radio Frequency Identification, is only a system to communicate wirelessly between two or many objects, where one of them emits radio signals and the other responds according to the received signal.
From here we can complicate the issue all we want and further more on technological radio waves, computer chips, resistors, impedance, with a lot of concepts unfriendly for end user.
However it may seem a bit contradictory, but the clear mission of RFID is well understood if seen as a new
"computer interface":
The much needed input data into computers as a reliably automate job, in real time without dedicated human resources.
The bar code is reliable only when you read it, when it performs the action of reading. The RFID is to ensure their automated readable at any time, at any place.
Where RFID can be useful?
The RFID can be useful when it is necessary a continuous data collection, or where not carried out by human inability or cost.
However, as a general summary, RFID can be useful both in internal procesess situations of enterprises, or processes for exchanging information and goods between diferntes supply chain actors. As an example:
Surely there are, and there will be many other applications of RFID Technology, but their common denominator is the reliability in processes, control and data acquisition in real time, with all the benefits that can be draw from it.
One of the major objectives that RFID can achieve, relative to the final consumer, is to be sure of tracking products, providing reliability and authentication to them.
