Identification by Radio frequency (RFID) is a technology that existed for more than half a century, however, in recent years, its potential has been taking advantage of to identify products and facilitate the logistic processes in which they operate both manufacturers and retailers within the sectors of consumer goods. Products by RFID or Radio frequency identification is a method that identifies reliably items using radio waves. The great advantage in relation to bar code technology is that the laser beams must see barcode to read it. On the other hand, radio waves do not require this line of reading and can be placed in different forms of texture of materials, such as corrugated cardboard or plastics. Electronic product (EPC) code is a unique number designed to uniquely identify any object at the global level, number which is also stored on an RFID TAG. The EPC is understood as the Standardization of RFID, leading within their standard aspects such as software, information systems and frequencies of operation, etc.
The electronic code of product (EPC) is the next generation of bar codes, basically the EPC is an encoding scheme developed by the Auto-ID Center that can uniquely identify an individual item, whether it is to be an article of consumption, box, pallet, good logistical or virtually anything else. Instead of being printed on paper as happens today with the barcode system, this number is inserted within an electronic tag which can be detected using radio (RIF) waves. This allows you to locate or track products throughout the supply chain and read these EPCs at a distance and out of direct line of reading. These technologies promise to improve and accelerate the operation of inventory, logistics in supply chains and payment processes and necessarily in the long-term it will do to improve the way they do business. RFID brings value to supply chains with new technologies and new business processes resulting from these technological changes in this first decade of the twenty-first century.
