Mobile Passport

Mobile Passport is an application officially recognized by the U.S. Customs and Border Protection, which means that you’re going to get a lot faster through the customs. All the information that’s stored in the passport can be added to the applications, along with other details such as duration of stay and purpose.
 
When all of these details are presented with via the NFC chip, the duration of the customs control is drastically reduced, not to mention the fact that it’s a different line and separate entry. For now, not all of the airports in the United States have support for this feature, but it’s getting more popular.
 
And, of course, users will have to remember to bring their passport as well, because the application is not a replacement.
