RFID & IoT FAQ

RFID (Radio-Frequency Identification) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of three components: an RFID tag (with a microchip and antenna), an RFID reader (that emits radio waves), and software to process the data. When a tag enters the reader's field, it transmits its stored data wirelessly — enabling automated identification without line-of-sight scanning.

There are three main types of RFID tags: Passive tags have no battery and are powered by the reader's signal — they're low-cost and ideal for inventory and asset tracking. Active tags have their own battery, offer longer read ranges (up to 100m), and are used for real-time location tracking. Semi-passive (BAP) tags have a battery for the chip but use the reader's signal to communicate, offering a balance of range and cost.

RFID system costs in Singapore vary based on scale and requirements. Passive RFID tags cost from S$0.10–S$2 each, while active tags range S$15–S$50. RFID readers cost S$500–S$5,000 depending on capability. A complete enterprise RFID solution including software, hardware, tags, and installation typically ranges from S$20,000 to S$200,000+.

RFID is widely adopted across Singapore industries including manufacturing (production line tracking, WIP management), logistics & warehousing (inventory management, shipment tracking), healthcare (medical equipment tracking, patient safety), pharmaceuticals (cold chain monitoring, compliance), chemicals (hazardous materials tracking), retail, construction, and government sectors.

RFID offers several advantages over barcodes: No line-of-sight required — RFID reads through packaging, pallets, and containers. Bulk scanning — read hundreds of tags simultaneously vs one barcode at a time. Read/write capability — RFID tags can store and update data. Durability — RFID tags withstand harsh environments where barcodes degrade. Automation — RFID enables hands-free, automated tracking. However, barcodes are cheaper per unit and sufficient for simple point-of-sale applications.

RFID asset tracking works by attaching RFID tags to assets (equipment, tools, inventory) and deploying RFID readers at key locations such as doorways, shelves, or zones. As tagged assets move through your facility, readers automatically capture their identity and location. This data flows into asset management software like Inventrack 6.0 which provides real-time dashboards, movement history, automated alerts, and analytics — giving you complete visibility over all assets.

RFID read range depends on the technology: LF (Low Frequency, 125–134 kHz) — up to 10cm, used for access control. HF (High Frequency, 13.56 MHz) — up to 1m, used for NFC payments and library systems. UHF (Ultra-High Frequency, 860–960 MHz) — up to 12m for passive tags, most common for asset tracking and inventory management. Active RFID (433 MHz or 2.4 GHz) — up to 100m+, used for real-time location systems (RTLS).

Yes. Modern RFID solutions integrate seamlessly with enterprise systems. Inventrack 6.0 provides native integration plugins for SAP, IBM Maximo, ServiceNow, and other ERP/EAM platforms. It also offers comprehensive REST APIs, GraphQL endpoints, and MQTT support for custom integrations. This means RFID data flows directly into your existing workflows without replacing your current systems.
