Defined as a pioneer of a brand new technological world, now leaded by the IoT, the smart tags already have changed the meaning of the word “efficiency” in business. Even if at first sight this technology has similar functions to the bar code, in fact it has represented a bolder step in improving the corporative efficiency and the time to market for solutions in the logistic, retail and industrial segments.
Developed by Massachusetts Institute of Technology researchers, the smart tags have emerged to facilitate the management and handling of goods in deposits and supermarkets, and to reduce obstacles in the tracking process. However, that was just the first of the benefits obtained with the investment in that technology.
The industry then also saw the advantages of the smart tags and the Radio Frequency Identification (RFId) technology. Some of the results using these tools were an increased quality in the generated data, from the first steps in manufacturing to distribution to the final customer, and the time saving with automated processes.
There are many reasons to deploy these smart tags in a business: a faster management of goods and supplies, a higher degree of precision on data gathering and the prevention of losses, frauds and thefts during transport processes. These are essential factors for the increase in production and competitiveness, providing this way a much more reduced time to the market.
How does a smart tag works?
The core structure of a smart tag is composed of three components: antenna, transceiver, and transponder. The antenna is responsible for the communication between the smart tag and the operational system, through the RFId. They are produced in multiple formats and provide different frequencies, which varies according to the demand and to the costs of each solution. The transceiver performs the data decryption; the transponder is the component dedicated to data storage.
Today, the Internet of Things has a key role in the evolution of that technology. Chips, sensors, and software development kits (SDKs) of the IoT incorporated devices have been well succeeded in creating connected solutions – which provide real-time connectivity. Near Field Communication (NFC), Bluetooth Low Energy (BLE) and the QR Code are good examples of the rapid progress of that technology, transforming the concept and the structure of a smart tag.
