EAN-13
European Article Number 13-digit
A 13-digit barcode standard used worldwide for marking retail products at the point of sale.
Technical Detail
Linear ean-13s encode data in parallel bars of varying width. EAN-13/UPC-A use 13/12 digits with a check digit (modulo 10 algorithm). Code 128 supports full ASCII with three character sets (A, B, C) and automatic set switching. Barcode scanners use laser or CCD sensors to read reflectance patterns — the quiet zone (blank space) before and after the barcode is critical for reliable scanning. Minimum bar width (X dimension) must be at least 0.25mm for reliable laser scanning.
Example
```javascript
// Generate Code 128 barcode
const barcode = generateBarcode({
data: 'PEASY-2026-001',
format: 'CODE128', // Also: EAN13, UPC-A, Code39
width: 2, // bar width in pixels
height: 80, // bar height
displayValue: true, // show text below
});
```
