Frequently Asked Questions
General RFID
RFID (Radio Frequency Identification) is a technology that uses radio waves to automatically identify and track objects, animals, or people. Unlike barcodes, it doesn’t need direct contact or line-of-sight scanning.
RFID works through three main components: a tag, a reader, and an antenna. The reader sends out radio waves, which activate the tag. The tag then sends back its stored information, which the reader captures and sends to a computer or software system.
RFID readers are devices that detect and read information from RFID tags. They send out radio signals, receive data from the tags, and pass that data to a system for processing. Readers can be fixed, handheld, or integrated into other devices.
RFID is used in many areas, including:
- Tracking inventory in warehouses and retail
- Managing assets in offices or hospitals
- Controlling access to buildings or events
- Monitoring livestock and pets
- Contactless payments
An RFID system typically includes:
- RFID tags – Attached to the item being tracked
- RFID readers – To scan the tags
- RFID antennas – To send and receive radio signals
- Software – To process and manage the data
An RFID reader is the device that communicates with RFID tags. It sends out radio waves to activate the tag and then reads the data the tag sends back. The reader then sends this information to a system for tracking or processing.
The RFID antenna is a component that transmits and receives radio signals between the reader and the tag. Its design determines the range and coverage area of the RFID system.
An RFID tag is a small device attached to an object, animal, or person to store identification information. It contains a microchip to hold data and an antenna to communicate with the reader. Tags can be passive, active, or semi-passive depending on their power source.
RFID tags respond to radio signals from an RFID reader.
- Passive tags use the reader’s energy to send data.
- Active tags have their own battery to transmit signals.
RFID tags are used for:
- Tracking products in retail and warehouses
- Monitoring assets in hospitals, offices, and factories
- Managing library books
- Controlling access to secure areas
- Tracking vehicles or livestock
RFID Fixed Readers
An RFID Fixed Reader is a stationary device installed at entry/exit points, production lines, warehouses, or secured zones to automatically detect and track RFID-tagged items.
They are commonly installed at warehouse gates, loading docks, production areas, secure rooms, and asset control points.
- Automated asset tracking
- High-speed bulk reading
- Reduced manual scanning
- Improved operational visibility
- Real-time monitoring
Yes. They are designed to read multiple RFID tags simultaneously, even in high-volume environments.
Barcode / RFID Handheld Readers
A handheld reader is a portable scanning device used to scan barcodes or read RFID tags for asset tracking, inventory control, and field operations.
Handheld readers are ideal for mobile operations, manual audits, inventory checks, and environments where fixed installation is not practical.
Yes. Many models support dual functionality, allowing users to scan traditional barcodes and RFID tags using one device.
Yes. Many industrial-grade handheld readers are rugged, durable, and designed for outdoor and harsh environments.
Barcode / RFID Printers
A barcode/RFID printer is a specialized device used to print barcode labels or encode RFID tags with unique identification data.
Yes. RFID printers can simultaneously print labels and encode RFID chips with asset or product information.
Manufacturing, logistics, retail, healthcare, and supply chain industries commonly use RFID printers for tracking and labeling.
Yes. Labels can be customized for durability, including resistance to heat, moisture, chemicals, and outdoor conditions.
RFID Labels & Tags
RFID labels and tags are small devices embedded with RFID chips that store unique identification data for tracking assets, products, or equipment.
UID offers various RFID tags including UHF tags, metal-mount tags, industrial tags, adhesive labels, and customized designs.
Yes. Specialized metal-mount RFID tags are designed to function effectively on metal surfaces.
Yes. We provide customized RFID labels and tags based on size, frequency, material, and environmental requirements.
RFID tags can be designed for harsh industrial environments and may be resistant to extreme temperatures, impact, and moisture.
RFID Software & Management Systems
RAMS is a smart tracking solution that uses RFID technology to monitor, manage, and control important assets such as equipment, tools, weapons, and documents. Each asset is assigned a unique tag, and readers automatically detect and record asset movement, usage, and storage in real time.
MES (Manufacturing Execution System) and WES (Warehouse Execution System) are enterprise systems that monitor and manage real-time production and warehouse operations. MES captures real-time production data, while WES manages inventory movement and workflow optimization.
PMS is an RFID-based system used to track the real-time location of staff, patients, or visitors within a facility. It enhances security, detects unauthorized entry, and assists during emergencies by providing instant headcounts.
WAMS is an RFID-based system designed to track and secure weapons and armoury assets. It uses biometric authentication and UHF RFID to secure dispensing and return of weapons, triggering immediate alerts for unauthorized movements.
EMS is an RFID-based visitor tracking system used during exhibitions and events. It tracks visitor entry/exit, booth visits, and duration spent at each booth to help exhibitors identify high-interest visitors and automate digital data capture.
RTS is an RFID-based system used to track athletes in events such as marathons, cycling, and motorsport races. It automatically tracks lap counts and participant movement, handling speeds exceeding 180 km/hr and assisting in emergency search and rescues.
