The EPC code is the latest product code being used today, replacing the ancient EAN codes or barcodes. The EPC code is unique to each product anywhere in the world.
The new EPC (Electronic Product Code) arises from the need to distinguish unit products of the same type or class. The current coding practice, EAN-13, cannot distinguish between two or more products with the same code.
The solution is clear. For each product code, a numerator is added making it possible to distinguish between two products of the same grouping or class.
On many occasions, it is difficult to introduce a 13 digit bar code for a product, and even more so if the bar code must be 20 or 24 digits - it is not a feasible solution for most unit products.
A tiny electronic chip of RFID technology, which has a size of 0.3 x 0.3 mm, is capable of storing up to 96 bits of information, i.e. 24 alpha-numeric characters. And in many cases, even the packaging of the product itself can be used as an antenna for receiving and transmitting a signal for reading.
It is now possible that each unit product of the same species can be identified uniquely in anywhere in the world. Basically, the EPC code contains:
RFID chips have been developed so that today it is possible to introduce many more data available additional reports. Therefore, for monitoring traceability and gaining visibility supply chain in real time, within the RFID chip itself it is possible to code in the user memory data as important as:
The EPC code and coding system unitary products, groups, pallets and containers is standardized worldwide. Today the use of standards in this globalized world is one of the keys to obtaining a traceability without duplicating information or expend unnecessary resources.
