RFID tags, what are they?
Radio Frequency Identification (RFID) tags represent an innovative and versatile technology that has transformed the way objects, animals and even people are identified and tracked in various environments, these tiny but powerful electronic tools, composed of a chip and an antenna , enable contactless communication via radio waves, providing the ability to collect and transmit information efficiently and in real time and since their emergence, RFID tags have played a fundamental role in a wide range of applications, from inventory management to access control and logistics.
What are RFID tags used for?
Inventory and Logistics Management: They allow the tracking and control of products and assets as they move along the supply chain.
Access control: They are used to manage access to restricted areas, such as buildings or facilities.
Asset Management: They facilitate the monitoring and control of equipment, machinery and other physical assets.
Vehicle Fleet Tracking: They are used to track and manage vehicles in transport or logistics companies.
Document and File Management: They help organize and locate documents in libraries or archives.
Product Tracking in the Health Industry: They make it easier to track medications and medical equipment.
Production and Quality Control: They are used to monitor and record production progress and product quality.
The implementation of rfid tags in industries can significantly improve operational efficiency, accuracy in asset tracking and management, as well as real-time visibility of processes, however, it is important to consider security and privacy aspects when using this technology.
What points should be considered when wanting to implement RFID tags in your company?
Consider infrastructure: It is necessary to carry out planning of the essential technological infrastructure, which includes servers, connectivity, among other elements, and the integration of the Middleware with the ERP systems, since in situations where this integration is not available, its implementation is recommended to guarantee efficient use of RFID technology.
Label selection: A fundamental aspect in the deployment involves the choice of the tag to be used, as well as the definition of an appropriate coding and placement strategy. During this process, it will be crucial to carry out reading validation tests to confirm its suitability.
Hardware: In this step, the establishment of the structure of the devices, their assembly and evaluation of the influence on the facilities is essential.
Measurement of results: After completing the essential tests, it is important to establish the parameters to evaluate the effect of the solution and determine if it meets the established criteria.
RFID tags in different industries
RFID tags (Radio Frequency Identification) work in industries through a process that involves communication between an RFID tag and an RFID reader or interrogator.
How this system operates is established below:
1. Signal emission: The RFID reader emits a radio frequency signal.
2. Reception by Label: When the signal from the reader reaches the RFID tag, the tag's antenna captures the energy of the radio frequency signal. This provides the energy needed to power the tag chip.
3. Chip Activation: Once powered, the tag chip activates and begins transmitting the information stored on it.
4. Data transmission: The RFID tag transmits stored data, which may include a unique identification number or other specific information associated with the object to which the tag is attached.
5. Reception by the Reader: The RFID reader receives the signal transmitted by the tag and processes it.
6. Processing and Use of Information: The reader processes the received information and sends it to an associated management system or database and depending on the configuration and purpose, this information can be used for a variety of purposes, such as inventory tracking, access control, asset tracking , among others.
