Frequently Asked Questions

What is a barcode and how does it work?

A barcode is a visual representation of data using parallel lines (bars) and spaces of varying widths. Barcode scanners read these patterns by measuring reflected light to decode the encoded information. Different barcode formats use different encoding schemes optimized for specific applications, such as retail (EAN/UPC), logistics (CODE128), or healthcare (pharmacode).

What is the difference between CODE128 and CODE39?

CODE128 is a high-density barcode that can encode all 128 ASCII characters, making it very compact and versatile. CODE39 is an older format that encodes uppercase letters, numbers, and some special characters, producing wider barcodes but being simpler to implement. CODE128 is generally preferred for modern applications due to its efficiency.

What is the difference between EAN-13 and UPC?

EAN-13 and UPC are both retail barcode standards. UPC (Universal Product Code) uses 12 digits and is primarily used in North America. EAN-13 (European Article Number) uses 13 digits and is the international standard. UPC-A codes can be represented as EAN-13 by adding a leading zero. Both formats include a check digit for error detection.

What is the best barcode format for general use?

CODE128 is typically the best choice for general-purpose barcode applications. It can encode any ASCII character, produces compact barcodes, and is widely supported by barcode scanners. For retail products, EAN-13 or UPC is required. For pharmaceutical applications, pharmacode is often mandated.

Can I use colored barcodes?

While you can create colored barcodes, the standard and most reliable configuration is black bars on a white background. This provides maximum contrast for scanner readability. If you use colors, ensure high contrast between the bars and background, and avoid red bars or backgrounds as many scanners use red laser light.
