Radio Frequency Identification (RFID) is revolutionizing how we track assets, inventory, people, and processes. Whether you're in retail, logistics, or healthcare, RFID offers a smarter, faster, and more accurate way to manage operations.
In this guide, we’ll break down how RFID tags work, their different types, and how companies are using them today to reduce errors, cut costs, and save time.
מה הם תגי RFID
A passive RFID tag is a small electronic device that uses radio waves to store and transmit data to nearby RFID readers. Unlike barcodes, תגי RFID don’t require a line of sight, allowing for contactless and automated tracking.
Each tag typically includes:
- A microchip to store data
- An antenna to transmit the signal
- A substrate (material like paper, plastic, or ABS) to hold components together
These tags are widely used for tracking inventory, securing assets, and automating identification systems across industries.
How RFID Tags Work
RFID technology functions through three main components:
- RFID Tag – Contains stored data such as a product ID, serial number, or timestamp.
- RFID Reader – Sends out radio waves to detect tags within range.
- Backend Software/System – Collects, processes, and visualizes the data from the reader.
There are two major tag categories:
- Passive RFID Tags: Powered by the energy from the reader. Cost-effective and common.
- Active RFID Tags: Battery-powered, enabling longer read ranges and continuous broadcasting.
Depending on the frequency and tag type, read ranges can vary from a few centimeters to over 100 meters.
Types of RFID Tags: What's the Difference?
Here’s how RFID tags differ based on their power source and use case:

Choosing the Right RFID Tag: A Quick Buyer’s Guide
Selecting the correct RFID tag is critical to the success of your tracking system. Using the wrong type can lead to weak signal performance, missed reads, environmental failure, or wasted budget.
Below is a step-by-step guide to help you choose the correct RFID tag based on your business needs, environmental conditions, and technical requirements.
1. What Are You Tagging?
The type, size, and material of the item you’re tagging will determine what kind of RFID tag you need.
- Metal items: Require on-metal RFID tags with a special structure to prevent signal reflection.
- Textiles or uniforms: Use washable fabric tags or sewn-in laundry RFID tags.
- Plastic or cardboard: Standard RFID labels or inlays work well.
- Tiny tools or assets: Choose small-form-factor RFID hard tags for a secure fit.
Always match tag size and material compatibility with your item’s surface.
2. Where Will It Be Used? (Environment)
Environmental factors play a big role in tag durability and performance.
| Condition | Recommended Tag Type |
|---|---|
| Outdoor exposure | Rugged, weatherproof RFID hard tags |
| High temperature (>160°C) | High-temp RFID tags (e.g., ceramic-based) |
| Moisture, water, chemicals | Waterproof tags with epoxy or ABS casing |
| Industrial abrasion | Encased or screw-mount industrial RFID tags |
For environments with interference (e.g., metal or liquid), always choose tags designed for those surfaces.
3. Required Read Range
Your application determines how far the tag must be readable from:
- Short-range (<1m): Access control, tool check-outs, patient wristbands
- Mid-range (1–5m): Retail inventory, asset tracking
- Long-range (5–30m): Pallet tracking, vehicle access, warehouse gates
- Ultra-long-range (30 m+): Logistics, fleet management (use active RFID tags)
Don’t overpay for long-range if short-range is sufficient. Match the range to the use case.
4. Mounting & Attachment Method
The way the tag will be applied also matters:
| Attachment Type | Use Case |
|---|---|
| Adhesive (sticker) | Books, boxes, shelves |
| Sew-in or heat-seal | Linens, uniforms |
| Screw-mount or rivet | Industrial equipment, vehicles |
| Zip tie/strap | Cables, pipes, and agricultural uses |
| Embedded/inlay | Packaging or product integration |
Select a tag with the correct form factor and mounting option for optimal durability and ease of application.
5. Memory & Encoding Needs
Not all RFID tags store the same amount of data. Choose based on what you need the tag to carry:
- EPC-only (96–128 bits): Item ID, SKU – standard for inventory
- User memory (512+ bits): Custom data like expiration date, service history
- Tamper-evident: Alerts when the tag is broken or removed
- Password protection: For sensitive or access-control systems
Use EPC Gen2-compliant tags for global compatibility.
6. One-Time Use or Reusable?
- One-time use (disposable): Ideal for retail, shipping, logistics
- Reusable tags: Use in industrial, healthcare, or high-value asset tracking to reduce long-term costs
Consider your ROI — sometimes reusable tags save more over time.
7. Frequency Compatibility
Ensure that your tag operates at the correct frequency for your region and reader system:
| תֶדֶר | בַּקָשָׁה |
|---|---|
| LF (125 kHz) | Short-range, animal tracking, and access control |
| HF (13.56 מגה-הרץ) | Smart cards, NFC, and healthcare |
| UHF (860–960 MHz) | Logistics, retail, industrial tracking |
Use UHF RFID tags for long-range applications, and HF/NFC for proximity and mobile scanning.
8. Budget Considerations
Pricing can range from $0.05 to $5+ per tag, depending on:
- Quantity ordered
- Type (label vs. hard tag)
- Features (memory, durability, mounting)
- Customization (printing, encoding)
Don’t just choose the cheapest option. The correct tag prevents loss, boosts efficiency, and lowers labor costs.
