QR code etched on a gas cylinder being scanned by a smartphone showing cylinder data
Technology

QR Code

QR codes are 2D barcodes that pack far more data than a 1D barcode and can be read from almost any angle by an ordinary smartphone camera.

For cylinders, this means each QR becomes a 'digital passport' — one scan opens the cylinder's identity, test dates, ownership and history, right in the palm of whoever is handling it.

Because everyone already carries a QR reader in their phone, QR is uniquely suited to customer- and field-facing tracking without any special hardware.
