If you're in the business of managing inventory, you know how critical it is to track your products' movements. One of the most popular methods of inventory tracking is through barcode scanning which requires a traditional line of sight scanner. But is this the most efficient way to track inventory? Or are there better alternatives like RFID and Infrared scanners?
RFID (radio-frequency identification) and Infrared scanners offer a wireless means of tracking data. In this article, we'll provide an unbiased comparison of the two technologies for inventory management.
What is an RFID Scanner?
RFID scanners use a combination of electromagnetic fields, antennae, and RFID tags to track inventory. The RFID system consists of a reading device that communicates wirelessly with an RFID tag that is attached to inventory. The reading device captures vital information about the tag like its unique identifier and data about the product.
What is an Infrared Scanner?
Infrared scanners utilize light rays outside the visible spectrum to communicate with objects. When you scan an object with an Infrared scanner, it attempts to interpret the reflected rays in real-time, capturing information from the object’s surface. Like barcode scanning, it requires a line of sight interaction.
Comparison of RFID and Infrared Scanners
| Technology | RFID | Infrared |
|---|---|---|
| Line of Sight Interaction | No | Yes |
| Range | Up to 300 feet | Up to 100 feet |
| The speed of scanning | Faster | Slower |
| Cost | More expensive | Cheaper |
| Data Tracking | Higher accuracy | Lower accuracy |
| Durable | Yes (Works in tough environments) | No (Interference with bright light) |
As you can see above, both technologies have different advantages and disadvantages. Each technology’s effectiveness is dependent on the goals, size of the inventory, and the working environment.
Conclusion
RFID and Infrared scanners offer varying degrees of performance and ease of use. RFID technology is a more expensive option, but it provides higher accuracy and greater flexibility, addressing the limitations of infrared scanning. RFID has a more extensive range than infrared and does not require a direct line of sight. In contrast, infrared scanners are more affordable and great for businesses with small-scale inventory management.
Both technologies can be used in tandem, creating an even better inventory management system. However, they are not solely interchangeable.
