Air travel has been in business for quite some time. Travelling by air which had been an affair that only the rich few could afford has become a normal thing now a day. One important piece of document that is required during the air travel is a boarding pass.
In an age when everyone is doing away with paper the boarding pass is one area which still requires some invention. With the number of people travelling by air increasing there should be some way to deal with the paper boarding pass. Boarding pass are issued to each individual travelling and I am sure they incur a huge cost to the airlines as well. One more thing to consider is that they are just a garbage after the travel and eliminating this critical piece could result huge paper saving as well.
One alternative that is being tried is a mobile boarding pass. This is being used by some airlines where a barcode/Qr Code is sent through sms to the person travelling. This barcode is the one similar to one that comes in the paper boarding pass. Even though mobile phones are something that everyone has this too has some implementation issues like what if the phone battery dies out or what if multiple people are travelling not all may be carrying a phone especially for child passenger.
One technology that captured my attention recently is the face unlock that some smartphones provide. I have been thinking if something of this sort could be used by the airlines. The steps would be as simple as capture the face image when issuing the ticket and then using the same to verify just before boarding.
This will require the airline to have some means to capture image during the initial check-in and then another hand held device can be used in the Gate just before boarding to validate the person travelling.
