Answers to questions about barcode scanners and data capturing, based on practical experience in logistics and industrial environments.
1. What are you going to scan? (1D vs. 2D)
This is the most important technical split.
1D Scanners (Laser/Linear Imager): For traditional "barcodes" (such as those on a milk carton). These are often cheaper and faster, but cannot read QR codes.
2D Scanners (Area Imagers): These can handle everything: 1D codes, QR codes, and even codes on a phone screen or damaged labels. Given the rise of digitalization, this is usually the future-proof choice.
2. How is the scanner connected?
Wired (USB): Ideal for a fixed location, such as a cash register or a stationary packing table. No hassle with batteries.
Wireless (Bluetooth/RF): Essential in a warehouse or for large items. Pay attention to the range (usually 10 to 100 meters from the base station).
3. What environment do you work in?
The durability of the scanner is expressed in its IP rating (protection against dust and water) and drop resistance.
Retail/Office: A lightweight, ergonomic model will suffice.
Warehouse/Industry: Choose a rugged scanner that can withstand a knock or two and has a high IP rating (e.g. IP65).
4. Special features
Long Range: Do you need to scan codes that are high up in a rack?
DPM (Direct Part Marking): For barcodes etched into metal or plastic.
Mobile Computer: If you want to adjust inventory levels directly on the scanner (think Android handheld).
5. How do I choose the right barcode scanner?
-
The choice depends on the barcode type (1D/2D), reading distance, environment (dust/humidity/cold), ergonomics, and whether you want to scan wirelessly or fixed-line. IPI recommends the right scanner or mobile computer based on your workflow.
6. Which scanner is suitable for warehouse use?
-
Warehouses require robust scanners with high read reliability and often wireless connectivity or integration into mobile terminals. The choice depends on labels, distance, and intensity.
7. When do I choose a fixed scanner instead of a handheld?
-
Fixed scanners are useful for fixed scanning points, high throughput, or automation (e.g., conveyors/gates). Handheld scanners are more flexible for picking and exceptions.
8. Can barcodes and RFID be used together?
-
Yes. Barcodes are ideal for visual identification and easy scanning, while RFID is ideal for fast bulk reading and automation. Identification Products Int. integrates both technologies into a single process.
