What is Barcode Scanning?
Barcode scanning captures data encoded in a barcode or 2D data matrix code using a handheld or fixed optical scanner, translating a printed pattern into digital information such as a part number, lot number or location without requiring an operator to manually type the data.
Because barcodes require direct line of sight between the scanner and the code, scanning is typically a deliberate, one-at-a-time action, whether scanning a single item during receiving or scanning each unit as it moves through a production or shipping process.
Barcode systems are widely valued for their simplicity and low cost compared to more advanced tracking technologies, using inexpensive printed labels and relatively affordable scanning hardware, making them accessible even for smaller manufacturers and warehouses.
Why is Barcode Scanning important?
Barcode scanning significantly reduces data entry errors compared to manual typing, since the scanned code is read directly rather than transcribed by hand, which is prone to typos and transposition mistakes.
By capturing data at the point of activity, such as receiving, production or shipping, barcode scanning supports real-time inventory accuracy and traceability without requiring a separate, delayed data entry step.
Because barcode technology is relatively inexpensive and widely understood, it offers an accessible entry point for organizations improving their data capture practices without the higher upfront investment RFID systems can require.
How does Barcode Scanning work?
A typical barcode scanning process includes:
- Barcode generation. Print a barcode or data matrix code encoding relevant product or location information.
- Label application. Apply the barcode label to the product, container or location.
- Scanning. Use a handheld or fixed scanner to read the code at key process points.
- System update. Automatically update inventory, production or shipping records based on the scanned data.
- Verification. Confirm scanned data matches expected values, flagging discrepancies for review.
- Reporting. Use captured scan data to support traceability and inventory reporting.
Barcode Scanning vs. RFID Tracking
| Comparison | Barcode Scanning | RFID Tracking |
|---|---|---|
| Line of sight | Required | Not required |
| Scanning method | One item at a time | Can read multiple tags simultaneously |
| Typical cost | Lower | Higher |
Real-world examples of Barcode Scanning
A manufacturer scans a barcode on an incoming material shipment, automatically recording the lot number and quantity into inventory without manual data entry.
A warehouse worker scans a barcode during picking, confirming the correct item and quantity before it is added to an outgoing shipment.
A production operator scans a work order barcode at the start of a job, automatically linking subsequent material and labor entries to the correct production record.
Regulations and standards related to Barcode Scanning
Barcode scanning is not a regulatory requirement itself, but the accurate, real-time data capture it enables supports traceability expectations found in ISO 9001, ISO 13485 and similar quality management standards.

Common mistakes with Barcode Scanning
Common mistakes include applying poor-quality or damaged barcode labels that become unreadable over time, particularly in harsh manufacturing environments involving heat, moisture or abrasion.
Other problems include inconsistent scanning discipline, where employees skip scanning steps under time pressure, creating gaps in otherwise continuous traceability data.
