This implementation bridges the gap between human-readable text and machine-readable code. However, it introduces a unique software requirement: the "start" and "stop" characters. Because a keyboard lacks a dedicated key for the barcode-specific asterisk function, the user must manually append asterisks to the data string before and after the desired text (e.g., DATA ). When rendered in the Code 39 font, these asterisks appear as the leading and trailing guard bars, creating a scannable barcode.

Ensure you print at a high enough resolution so the bars don't "bleed" together, which can cause scanning errors. Common Use Cases

Code 39 is the standard for many Department of Defense (LOGMARS) applications. Final Tips for Success

Furthermore, the font approach allows for seamless integration into existing software ecosystems. A user can generate a barcode within a Microsoft Word document, an Excel spreadsheet, or a Crystal Report simply by changing the font selection. This eliminates the need for ActiveX controls, plug-ins, or proprietary design software. For small businesses and internal logistics operations, this ease of use offers a low barrier to entry for asset tracking and identification.
