A vulnerability in US domestic airline boarding pass barcodes could allow travellers to bring unauthorised items on board, says a security expert.
The codes reveal what kind of airport checks a passenger will face and can be read by smartphones, he says.
It could undermine the US’s PreCheck system which randomly decides which frequent fliers can skip part of the pre-boarding security process.
The barcodes could allow passengers to work out if they had been picked.
Implying that Airport security is worth a God-Damn at finding threats.
