Along the travel journey, from check-in to security, to boarding etc, incorporating biometrics along the way requires various organizations to be in agreement before the entire process could be successfully implemented.
Increasingly, we see that more airports are adopting this technology though, and it's been found that more than 90 percent of travelers have indicated that they would prefer or at least be open to experimenting with this seamless travel approach.
Your Face: The Single Travel Token
Ultimately, you won't need the passport and your boarding pass to go on vacation, you are just going to need your face. And from boosting airport capacity to reducing boarding times etc, airports and other agencies have been eager to embrace this approach, as well as government agencies, asserting that it's going to bring with it a multitude of benefits.
Not everyone is so eager for the change though, and the advancement of this technology today that's already seen in various airports has caused some alarm with travelers, fueling privacy concerns.
As well, in some cases scanning faces and complying with those biometric surveillance objectives, has been found to place a costly burden on airports, delaying flights, and inconveniencing travelers.
Various civil liberties organizations have affirmed that the government should not pursue this approach so aggressively, warning that facial recognition is the most dangerous biometric to be utilizing. For example, it's much easier to use facial recognition on many people at one time in an area that you might want to scan, than it would be to scan many fingerprints as an alternative. There are growing concerns that this technology will inevitably be expanded into other areas of society as well, and we can already see that it's being used at sporting events and more arenas outside of airport spaces.
Facial recognition has in the past also demonstrated to operate at a high error rate and there is the possibility that people will be wrongfully identified and therefore targeted as a result.
Still, it's reported that today most Americans do trust facial recognition technology.
There have been calls for travelers to opt out of having their faces scanned while that's still an option for them. You can find various reports online detailing how someone might go about opting out. The technology is still being rolled out quickly, and it's expected that by fall 2020 you might be able to find it in use at almost every major airport in the United States.
