EAN Check
Validate, repair and print product barcodes like EAN, UPC and GTIN.
Connects to the EAN Check barcode service. Muse can add or verify GS1 check digits, identify an unknown code such as an ISBN, SSCC or Amazon FNSKU, recover a GTIN with unreadable digits, convert UPC-E and ISBN formats, parse GS1-128 data, and generate print-ready barcode images.
Try asking Muse: "Check whether the barcode numbers on this product label are valid and tell me what kind of codes they are."

Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
