# BARCODE

The BARCODE component captures barcode data from the mobile device.

Scan mode behavior:

• SINGLE SCAN or MULTIPLE SCAN - Opens the camera to capture barcodes
• MANUAL INPUT - Opens the keyboard for manual entry (compatible with built-in barcode scanners)

For PDA device integration, see: Send barcodes from an Android PDA scanner to a computer.

Validate barcodes using regular expressions.

Example: Accept only numeric barcodes (e.g., 000001, 000002):

^[0-9]*$

Regular expressions enable various validation rules:

• Barcode length validation
• Content pattern matching
• Prefix/suffix requirements

Restrict scanning to specific barcode formats.

Example: If a label contains both a QR code and a 1D barcode, configure the scanner to capture only the QR code:

The scanner will ignore the 1D barcode and capture only the QR code.
