Bulk Scanning
This page explains the onboard memory feature found on some keywedge scanners, why it is problematic for use with xAssets, and what to use instead.
What Is Bulk Scanning?
Some keyboard wedge scanners can store barcodes in onboard memory when not connected to a computer. This is sometimes called "batch mode" or "inventory mode". When you later connect the scanner (or press the scan trigger), it sends all stored barcodes to the keyboard buffer in rapid succession.
Why Bulk Scanning Is Not Recommended
This approach is not recommended for more than a few barcodes. The main risks are:
| Risk | Description |
|---|---|
| No verification | You cannot confirm what was scanned until the data reaches xAssets. If a barcode was misread or the wrong item was scanned, you will not know until after the transfer. |
| Data errors | A large burst of characters injected into the keyboard buffer can result in missed or extra characters, leading to incorrect barcode values in xAssets. |
| Application readiness | xAssets may not be able to process a rapid stream of barcodes arriving in a single batch. The search or input field needs time to process each barcode before receiving the next one. |
| No context | Unlike an audit workflow, bulk-scanned barcodes arrive without any associated data (location, condition, quantity), limiting their usefulness. |
What to Use Instead
For reliable multi-barcode scanning with xAssets, use one of these alternatives:
| Method | When to Use |
|---|---|
| Barcode Search dialog | Scanning multiple barcodes at a desk or workstation. Each scan is verified in real time. See Searching with a Keywedge Scanner. |
| Keywedge audit scanning | Scanning assets during a formal audit with an audit form. See Barcode Audits and the xAssets Barcoding Guide. |
| Intelligent scanner | Collecting barcodes offline and importing them. Best for large-volume audits. See the xAssets Barcoding Guide. |
Tip: If you need offline scanning capability but only have keywedge scanners, consider upgrading to an intelligent scanner for audit workflows. The investment pays for itself in data accuracy and reduced rework.
If You Must Use Bulk Scanning
If you do use the onboard memory feature of a keywedge scanner (for example, scanning a handful of barcodes in an area without network access), follow these precautions:
- Limit the number of barcodes -- keep it under 10 per batch to minimize buffer errors.
- Open the Barcode Search dialog first -- this gives xAssets the best chance of processing each barcode as it arrives.
- Verify the results immediately -- compare the scanned barcode count against the number of items you physically scanned.
- Re-scan any missing barcodes -- if the count does not match, scan the missing items individually.
