Boarding pass barcodes 'can be read by smartphones'
• BBC NewsA 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.
