RFID Technology

What is RFID Technology?

RFID Technology - "Radio Frequency Identification" (RFID) is the automatic identification that stores and retrieves data remotely via an RFID tag. RFID can make simultaneous readings of objects, products, vehicles or people, substantially speeding up processes of identification, it is possible to read data from the tags embedded in objects or products, even when there is no line of sight between the device and the RFID reader.

RFID systems consist of three basic components: an antenna, a reader and a tag (RF tag). The operation of RFID is based on this simple concept: It sends a signal to an electrical device that is activated and returns the signal (passive system) or emits a signal (active system).

Passive System

They are usually read-only. They have a lower operating range and less memory than active tags, no battery and draw power from the reader, which sends out electromagnetic waves that carry current to the antenna of the tag.

Active System

Unlike passive tags, they have a transmitter and their own power supply, have read-write capabilities, higher memory capacity and much greater operating range. The power supply is used to run the microchip and send a signal to a reader.

The data generated is stored by a parent application. The antenna generates a magnetic field that activates the magnetic label and enables communication between the tag (Tag) and the Reader.

What is EPC?

EPC - Electronic Product Code (Electronic Product Code) is the new generation system for automatic identification of products, uses a unique serial number (unique) to identify each individual package of a product and makes it possible to automatically monitor the products from their manufacture to the store, reaching to the final customer.

What is NFC?

NFC is a short-range wireless technology that allows interconnection between electronic devices in an intuitive, easy and simple operation that allows a distance of less than 10 centimeters.

NFC technology allows data exchange between devices (mobile phones, PDAs, or PCs) and it is a complementary technology.

RFID Benefits

The most significant advantage of RFID technology is the ability of electronic supervision of the products. Unlike the bar code system, the inventory can be monitored at each and every one of the supply chain; eradicate the disadvantages of barcodes, where each article must be scanned manually, can only store a limited amount of information and must be changed each time information changes. The bar codes are unreadable when dirty or damaged.

Another advantage of RFID is that it does not require direct contact or line of sight to function properly. The tags can be read in any environment, whether there is presence of snow, fog, ice, paint, dirt or other conditions. RFID tags can also be read very quickly: in most cases responding in less than 100 milliseconds.
