The USA "War on Tourism" continues with the start of "Biometric" recording of airline passengersan from countries requiring a visa.
N.B. an extra "15 seconds" delay per passenger means that the last people off a 400 seat Jumbo jet will be delayed by over 1 hour and 40 minutes. In practice, this delay will be much longer.
The digital fingerprint scanners which seem to be in use are of the type which are prone to errors due to the buildup of fingerpint oil, grime and sweat etc. leading to even more delays and possible misidentifications.
Not suprisingly these discriminatory security measures are already producing a backlash. The Brazilian authorities are photographing and fingerprinting US visitors to Brazil in retaliation, presumably so that they can send back some sort of message to the US Government during this election year.
The countries whose tourists are allowed into the USA under the visa waiver scheme, including the UK, will also have to undergo this procedure from October this year.
The plan is, eventually for the whole fingerprinting and photographing process to be done again on exit from the USA.
