What is RFID Technology?
RFID (Radio-Frequency Identification) is a technology that allows objects to be identified and tracked without touching them. It works with small labels called tags, which send information to readers using radio waves.
It is used in inventory management, product tracking, libraries, transportation, and contactless payments, making everything faster and easier to organize.
The antenna emits radio signals to activate the Tag, read, and write data. It acts as a channel between the Tag and the transceiver, which controls data acquisition and system communication. It can have various shapes and sizes and can be installed at gates, tolls, or other locations to capture data from people or objects. The electromagnetic field produced can be constant or activated by a sensor.
The transceiver, together with the decoder, forms the RFID reader. It can be handheld or fixed, and emits radio waves with varying ranges depending on the type of Tag. When the Tag passes through the electromagnetic field, the reader decodes the data from the Tag's integrated circuit and sends it to the computer.
RFID Tags come in various shapes and sizes, from small pins for animal identification to credit cards for access control. They can be active (with battery, read/write capability, and longer range) or passive (activated by the reader, smaller, cheaper, and long-lasting).
Have an internal battery, can read/write, with a range of up to 100 meters. More expensive and have a limited lifespan of around 3 to 5 years.
Do not have an external power source and are activated by the reader's field. They are smaller, lighter, cheaper, and have an almost unlimited lifespan, but with shorter range and require more powerful readers.
Short range, low cost. Used in access control and animal identification.
The High-frequency band consists of frequencies from 3 MHz to 30 MHZ. Accordingly, major High-frequency RFID cards operate at 13.56 MHZ. In comparison to Low-frequency, High-frequency systems face a moderate level of radio-wave interference
High range and read speed. Used in wagon tracking, automated tolls, etc., but with higher cost.
Imagine having the power to track every item in your inventory or production process, knowing its exact location, history, and status in real time—without the need for visual contact. This is not science fiction; it’s RFID Technology (Radio Frequency Identification), and it’s ready to revolutionize the way you operate. RFID is not just a replacement for barcodes; it’s a quantum leap in efficiency and accuracy. Here’s why successful investors and managers are adopting this innovation:
Say goodbye to Where is it?: RFID tags can be read from meters away and in bulk — dozens or even hundreds of items per second. This means inventories done in minutes, not days, freeing your team for more strategic tasks.
Informed Decisions: With real-time data on asset flow, you can identify bottlenecks, optimize logistics routes, and ensure the right product is in the right place at the right time.
Unprecedented Automation: RFID enables automation of key processes such as receiving, shipping, and inventory counting. Your employees stop acting as human scanners and become information managers.
Zero Reading Errors: Unlike barcodes, RFID tags don’t need to be visible or oriented in a specific way to be read, eliminating most manual errors and rework.
Fraud Prevention: In retail and security environments, RFID enables unique and non-transferable tracking of products, making it difficult to counterfeit or divert high-value goods.
Asset Monitoring: Instantly know when a valuable asset (tools, IT equipment, etc.) leaves an authorized area, preventing theft and ensuring resources are always available for operation.
In a market that demands increasing precision and agility, ACURA Technologies has established itself as the true pioneer and driving force in the adoption of RFID technology (Radio Frequency Identification) in Brazil and across Latin America. Since its founding in the late 1990s, ACURA has not only provided hardware but has also pioneered the large-scale application of RFID, transforming entire sectors of the regional economy.
Retail Transformation: ACURA provided the technological foundation for one of the largest and most impressive RFID success stories in global retail. At Centauro (Grupo SBF), the implementation of the technology in record time elevated inventory accuracy to nearly 100%, optimizing the entire supply chain and improving both customer and employee experience.
Infrastructure and Mobility: The company demonstrated strong leadership in the ITS (Intelligent Transportation Systems) sector, being a key supplier of RFID readers for toll systems and vehicle access control in various ports, airports, residential complexes, and shopping centers.
Cross-Sector Adoption: ACURA’s expertise extended beyond retail and logistics, reaching essential industries such as mining, steel, agriculture, food processing, and healthcare, establishing RFID as an indispensable tool for asset management, production control, and traceability.
ACURA Technologies’ pioneering and excellence were recognized in 2022 with its acquisition by HID Global, a world leader in trusted identity solutions. By becoming part of HID Global’s portfolio, ACURA not only strengthened its leadership position but also elevated its commitment to developing next-generation RFID solutions to a new level, ensuring that the Latin American market has access to a complete and customizable portfolio of readers, tags, and antennas. Choosing ACURA (now part of HID Global) is choosing the experience of a company that helped build the RFID market in the region, ensuring that your project not only works but becomes a new benchmark in efficiency and innovation.
