Know everthing about RFid




It is already an act that has become a routine in everyone's life: when making a purchase, an optical reader reads the bar code, identifying what the product is and also its price and if you make a lot of purchases, this process can be a as long as it takes.


There is a technology that has been studied for some years and can replace this practice known to us all. It is known as RFID (acronym for Radio Frequency Identification) and one of its applications would be in stores and supermarkets.


That's because this is a short-range communication technology and RFID tags could be read automatically by sensors at the supermarket outlet, for example, dispensing with manual and individual barcode scanning. In addition, there are several other applications for this system, which will be discussed later in this article.

RFid Function

How it works?


An RFID system consists basically of an antenna, a transceiver, which reads the signal and transfers the information to a reader device, and also a transponder or RF (radio frequency) tag, which shall contain the circuit and the information to be transmitted. These labels can be present in people, animals, products, packaging, in short, in diverse equipment.


Thus, the antenna transmits the information, emitting the signal from the integrated circuit to transmit its information to the reader, which in turn converts RFID radio waves to digital information. Now, after being converted, they can be read and understood by a computer to have their data analyzed.



RFID tags


There are two types of RFID tags: passive and active.


• Passive - These tags use the radio frequency of the player to transmit your signal and usually have their information recorded permanently when they are manufactured. However, some of these labels are "rewritable".


• Active - Active tags are much more sophisticated and expensive and have a battery of their own to transmit their signal over a reasonable distance, as well as allowing storage in RAM capable of storing up to 32 KB.

And where can RFID be useful?
The radio frequency identification system can act on several fronts, ranging from medical and veterinary applications to use for payment and bar code replacement. Inventory management, inventory, tracking tracking. Get to know some of these RFID applications now.




Asset Management RFid

The RFID Label Equity Inventory service encompasses all stages of the Asset Inventory, but with the ease of use of RFID smart tag technology.


The solutions range from RFID tags or tags that can be customized and encapsulated depending on the type of application, the RFMOBI Inventory (physical inventory software) compatible for reading the tags and also the equity software, to give continuity to the management of the fixed assets.


Among the advantages of using RFID in the equity control are the batch reading of several assets, which allow the reduction of inventory time and accelerate the process of physical revision of the fixed assets.




Supply Chain RFid

One of the fertile fields for the application of RFID technology is in the management of the supply chain (Supply Chain Management). RFID functionality enables the development of more flexible and intelligent logistics applications. 


How RFID adds value to products and services in the logistics chain:




These examples show that the benefits of RFID in Logistics go far beyond controlling the movement and storage of materials along the supply chain. Well applied, RFID technology can change the way you do business, help improve services, better serve customers, increase product quality, reduce time, cost of distribution, and move materials.


The main functionalities that allow us to go beyond the boundaries of managerial activities and to add value in the products and services are:


  • Store product data in addition to the item code.
  • RFID of the active type can send data, indicative of situation, humidity, temperature and even the exact location if combined with a GPS.
  • RFID UHF can reach up to more than 10 meters depending on the environment.
  • Possibility of reading and writing data (Read-Write).
  • RF capture of objects in non-uniform movements.
  • The reading does not have to be static and straight as in the bar code.
  • Capture distance greater than optical reader (Read range).
  • Write unique product code or non-changeable part (Read only).
  • RFID tag reuse.

Improved service levels by adding flexibility and intelligence to processes.


In the manufacturing: Automated receipt integrated to the PCP allows to continue without loss of time waiting for the notification of receipt of the material.


Assembly line: Custom production of products.

In retail:

Automatic replenishment of missing items, expiration date control, expedite check-out, stock control, return control.


Avoid forgery by writing the unique code of the product non-changeable.


Check boxes, pallets and shelves at the top without having to open or without eye contact.


Reduction in the total time of the requested cycle until delivery of the merchandise.


Speed ​​gains in material movement.


Reduction of errors in the delivery of customer orders.


Elimination of one-by-one barcode scanning processes and consequent read speed gain with simultaneous capture of multiple tags.


More agility and speed in locating materials.


Tracking of people, animals and objects.


Inventory control: Automatic recording of material inputs and outputs.


Monitoring and control of logistics operations increasing safety.


Make sure the RFID tag has been captured by recording the date / time of the reading.


Inventory of products and materials quickly with less labor.




Supply Chain RFid

Of course there are also factors that hinder the application of RFID technology. Radio waves can be prevented from propagating if they encounter any obstacles. Metals influence the distance of capture. Liquids and the human body itself can also prevent capture. Capture distance if not well planned can cause problems such as opening a gate improperly.


By looking at the features and benefits that the use of technology can provide, we can conclude that RFID can be the competitive edge to make business more sustainable. The important thing is to study the technology well, do a good project, redesign the processes, develop the applications and do a careful pilot test before leaving by placing the RFID tags on the materials.
