RFID is about communication between modern objects. The different uses of RFID technology can be applied within a wide range of business processes.

 

RFID technology, which responds to the initials of Radio Frequency Identification, is nothing more than a system to communicate wirelessly between two or more objects, where one emits radio signals and the other responds based on the received signal.

From here we can complicate the issue all we want and go down to the technological depths of radio waves, chips, resistors, impedances; and a host of concepts with the end user unfriendly terminology.

However, and although it seems a bit contradictory, the clear mission of RFID technology is well understood if it is seen as a "new computer interface".

Reliably automate much needed input in computers, in real time and without dedicating human resources.
The bar code is reliable only when you read when reading action is performed. RFID technology is to ensure automatic reading anytime and anywhere.

Where it can be useful RFID technology?

RFID technology can be useful where continuous data records have to be made, or where not performed for human impossibility or cost. However, as an overview, the RFID can be useful both in domestic situations of enterprises, proprietary processes or processes of exchange of information and goods between diferntes chain agents. As an example:

Inventory control.
Traceability.
Movement of goods.
Industrial process control.
Process automation.
Asset tracking.
Access control and vehicles.
Optimization in hospitals.
Logistics and storage.
 

The fundamental purpose RFID transmit the identity of an object or product when activated by an RFID antenna. There are different rf frequencies and each carries a different use. The use of different frequencies is fully generalized and approved worldwide by different entities.

Rfid main frequencies:

Passive RFID UHF (860-960 MHz)
NFC and RFID Passive HF (13,56Mhz)
