Short story, checked in online but still needed to pickup a physical boarding pass (online didn’t generate a qr/barcode code)

Security would not let me through without a barcode to scan.

I remember seeing on HN generators and decoders of boarding passes.

Searched and found the link above.

Got me through security at Hong Kong airport, otherwise I was out of pocket 100s of dollars and alot of in convenience. Brilliant.

Thanks fellow HNs
