A barcode scanner may seem like a small purchase, but the wrong choice can slow down warehouse operations. Workers may have to share devices, batteries may run out during a shift and scanning an item may not provide the information needed for the next task.
Three common options are handheld barcode scanners, mobile computers and fixed scanners. Although all three read barcodes, each serves a different purpose. This guide compares their uses, benefits and limitations to help you choose the right barcode scanner for warehouse operations.
Handheld vs. Mobile Computer vs. Fixed Scanner: Quick Comparison
| Scanner type | Best suited for | Main limitation |
| Handheld scanner | Packing, receiving, returns and workstations | Often needs a connected computer or terminal |
| Mobile computer | Picking, put-away, stock counting and loading | Higher cost and battery requirements |
| Fixed scanner | Conveyor belts, sorting lines and automated checkpoints | Requires suitable installation and label positioning |
Quick guide: Choose a handheld scanner for workstation tasks, a mobile computer for employees moving around the warehouse and a fixed scanner for items passing through a designated scanning point.
Handheld Barcode Scanners
A handheld barcode scanner is a dedicated device that reads barcodes on products, cartons and pallets. Depending on the model, it connects to a computer or terminal through a cable or wireless connection.
Many modern scanners use 2D imaging technology. Supported models can read traditional linear barcodes as well as QR codes and Data Matrix codes.
Best uses
- Scanning incoming goods at receiving desks
- Verifying items during packing
- Processing customer returns
- Checking stock at fixed workstations
Benefits: Handheld scanners are generally easy to learn and can be a cost-effective choice for specific scanning points. They work well when employees scan items at a desk or packing station.
Limitations: A basic scanner does not usually display warehouse tasks or instructions on its own. Employees may need a connected computer or terminal to view item details and confirm transactions. In a large warehouse, repeatedly returning to a workstation can also increase walking time.
Mobile Computers with Built-in Barcode Scanners
A mobile computer combines a barcode scanner, screen, processor and wireless connectivity in one device. With suitable warehouse software, employees can scan items, view instructions and confirm transactions while moving between storage locations.
For example, a picker can scan a storage location, check the required quantity, scan the product and confirm the pick in the warehouse management system (WMS).
Best uses
- Order picking and put-away
- Receiving and stock verification
- Cycle counting
- Loading and dispatch checks
- Recording damaged goods when the device and application support image capture
Benefits: Mobile computers allow employees to scan items without repeatedly returning to a desk. When connected to a suitable WMS, they can help staff follow assigned tasks, confirm quantities and record stock movements.
Limitations: Mobile computers generally cost more than basic handheld scanners. Battery life, wireless coverage, durability and software compatibility should be checked before purchase. Test connectivity in storage aisles, loading bays and other areas where employees will use the devices.
Fixed Barcode Scanners
Fixed barcode scanners are installed at designated points such as conveyor belts, sorting lines and automated inspection stations. They read items as they pass through the scanning area, reducing the need for employees to scan every item manually.
Some models use imaging technology to read labels from different angles. Performance depends on the scanner’s capabilities, barcode quality, item speed and installation setup.
Best uses
- High-volume parcel sorting
- Conveyor-based material movement
- Automated scanning checkpoints
- Repeated barcode checks on production or distribution lines
Benefits: Fixed scanners can support repeated scanning and reduce manual work at suitable points in an operation.
Limitations: Installation requires careful planning. The scanner must be positioned correctly, labels must be readable and the system must account for items that cannot be scanned. Employees also need a clear process for handling unreadable labels and other exceptions.
In automated warehouses, a Warehouse Control System (WCS) helps coordinate warehouse software with equipment such as conveyors and automated storage systems. The PALMS™ Warehouse Control System supports equipment integration, material-flow control and barcode tracking in automated warehouse operations.
Five Questions to Ask Before Choosing a Scanner
1. What happens after the scan?
If an employee only needs to confirm a barcode at a packing desk, a handheld scanner may be sufficient. If the employee must view tasks, check quantities and update records while moving, a mobile computer may be more suitable.
2. How far do employees move?
Review the tasks employees perform during a typical shift. Workers who travel between storage locations may benefit from mobile devices. Employees who work at fixed stations may not need a mobile computer for every task.
3. What is the warehouse environment like?
Consider dust, moisture, temperature, drops and daily usage. Check the device’s protection and durability ratings against actual working conditions. Cold storage and busy loading areas may require different specifications from a clean packing station.
4. Which barcode formats must be read?
List the barcode formats used on products, cartons, pallets and storage locations. If suppliers use different labels or your operation needs 2D codes, confirm that the selected scanner supports them. Test it with actual warehouse labels before purchasing devices in bulk.
5. Will it work with your WMS and ERP?
A scanner is only one part of the process. Confirm that the device works with your warehouse application, operating system and wireless network. Check how scans are recorded, how errors are handled and whether inventory updates reach the relevant systems correctly.
Common Barcode Scanner Selection Mistakes
Avoid these mistakes when selecting warehouse scanning equipment:
- Choosing by price alone: A low-cost device may not suit heavy daily use or the warehouse environment.
- Ignoring barcode quality: Damaged, faded or poorly printed labels can cause reading problems even with suitable equipment.
- Skipping a pilot test: Test devices with actual products, labels and warehouse staff before making a large purchase.
- Overlooking battery needs: Check operating time, charging arrangements and spare battery requirements.
- Forgetting software compatibility: Confirm that scanning transactions work correctly with your WMS or ERP before deployment.
Which Scanner Is Right for Your Warehouse?
The right choice depends on the size of the operation, the tasks involved and how goods move through the facility.
Small online store: A handheld scanner at the packing desk may be enough for basic order checks and dispatch preparation.
Distribution warehouse: Mobile computers can support picking, put-away and stock counting, while handheld scanners can serve packing and returns stations.
High-volume parcel facility: Fixed scanners can read parcels at conveyor checkpoints. Mobile computers or handheld devices can help employees manage unreadable labels and other exceptions.
Some warehouses benefit from a combination of all three. The aim is to select equipment that fits each task rather than purchasing the same device for every employee.
How PALMS™ Supports Warehouse Barcode Scanning
Barcode scanners capture information from labels, while warehouse software uses that information to support inventory and order processes. A suitable system can connect scanning activities with receiving, picking, location identification and dispatch records.
The PALMS™ Barcode Scanning System supports processes such as inward stock labelling, barcode quality checks, barcode-based picking, location identification and loading or unloading. These features can support more consistent stock identification and recording across warehouse activities.
Before selecting scanning devices, review your warehouse workflows, label formats, software requirements and connectivity needs. Choosing suitable hardware and software together can help employees record stock movements consistently and reduce manual data entry.
Conclusion
Choosing the right barcode scanner depends on your warehouse activities, working environment and software requirements. Handheld scanners suit fixed workstations, mobile computers support employees working across storage areas and fixed scanners help automate repeated scanning points.
Before purchasing, test the devices with actual warehouse labels and workflows and confirm compatibility with your WMS or ERP. The right setup can help improve scanning processes and reduce avoidable manual work.
