Short story, checked in online but still needed to pickup a physical boarding pass (online didn’t generate a qr/barcode code)<p>Security would not let me through without a barcode to scan.<p>I remember seeing on HN generators and decoders of boarding passes.<p>Searched and found the link above.<p>Got me through security at Hong Kong airport, otherwise I was out of pocket 100s of dollars and alot of in convenience. Brilliant.<p>Thanks fellow HNs
