Barcode Scanning

What is Warehouse Barcode Scanning?

Warehouse barcode scanning uses optical readers to capture product and location data encoded in linear or 2D barcode patterns.

These optical readers decode these patterns into digital information that updates inventory systems in real time.

What are the Benefits of Implementing a Warehouse Barcode System?

Implementing barcode scanning in a warehouse environment offers many advantages including:

  • Instant updates: Warehouse barcode scanning enables real-time inventory management as items move through receiving, putaway, picking and shipping.

  • Reduced errors: Warehouse barcode scanning eliminates manual data entry and reduces mispicks when paired with a warehouse management system (WMS).

  • Faster workflow: Operatives can pick and pack orders more quickly, saving time and lowering labor costs.

Types of Warehouse Scanning Technology

There are multiple types of warehouse scanners operatives can use.

Handheld Barcode Scanners

These portable, one-handed scanners connect to mobile computers or warehouse management systems (WMS).

Handheld barcode scanners use Bluetooth or radio frequencies (RF) to connect to a mobile computer or WMS.

Handheld Bluetooth barcode scanners and RF barcode scanners are the most common tools used in inventory barcode scanning.

Mobile Barcode Scanners

Mobile barcode scanning uses smartphones or tablets with camera-based scanning apps.

The advantage of mobile barcode scanning is that it’s flexible, making it ideal for smaller operations or warehouses using temporary staff.

Industrial-grade mobile computers are also available, with dedicated scan buttons and rugged hardware for high-volume environments.

Ring Scanners and Glove Scanners

Ring scanners are worn on an operative’s finger and glove scanners are worn across the front of the hand.

While these warehouse scanning technologies aren’t the most durable, they allow for hands-free operation, increasing picking speed and reducing the risk of accidents.

Fixed Position Scanners

Fixed-position scanners stay in one place, usually near conveyor systems or dock doors.

This warehouse scanning technology automatically captures barcodes as items pass, allowing for high-speed, high-volume scanning.

How WMS Uses Barcode Scanning

Barcode scanning technology integrates with WMS to validate every warehouse transaction.

Operatives scan locations to confirm they’re in the right place. Then if they scan the wrong item, the WMS sends an alert to the device, alerting them to the error. This dual verification reduces mispicks.

When a barcode is scanned, the WMS instantly updates the status of an item, ensuring accurate stock levels in real-time.

Cycle counting becomes more efficient as operatives scan locations and products, with the WMS comparing physical counts to system records and flagging discrepancies for investigation.
