Barcode display
Puts a scannable barcode on screen for testing — the value in the URL is reproduced exactly, byte for byte, never corrected or completed. Rendered in your browser; nothing is sent anywhere.
/barcode?data=5012345678900— symbology detected from the value: a valid EAN-13, UPC-A or EAN-8 checksum renders as that type; anything else renders as Code 128./barcode?data=5012345678932&type=code128— explicittype:auto·ean13·ean8·upca·code128·code39·itf14·qr·datamatrix. If the value can’t be encoded as the requested type it renders as Code 128 with a note saying why.&scale=2— bigger modules;&plain=1— no page furniture, for embedding.
