Mobile Passport Control app [View all]

If you’re traveling internationally, this app is a godsend. It allows you to complete the customs and immigration questionnaires as soon as you land back in the US. We were returning from Japan and as we were taxiing to the terminal, we turned our phones back on, submitted the forms and were sent a QR code. There were hundreds in the regular passport control line but only three in the MPC line. They scan the QR code and your passport. We were done in five minutes.
