When going through customs at an airport, you don't need to show a physical Global Entry card.

The card is not required for members to use the expedited customs lanes for air travel. The cards are supposed to cross land borders into the US.

Over the course of the year, we have heard from a number of travelers who have been asked to show their physical card. There are four different scenarios where you may want to have your card handy.

If you don't get a Real ID by the May deadline, you can still use a Global Entry card as a backup form of identification, but it's a handy card to have in your possession.

We have heard from travelers who never received a physical Global Entry card, or who have no idea where their card is, when we talked about these cards in the past.

If you are a current member of the program, here is what you can do to obtain a new card.

This is only for replacement cards and is not the same as a card renewal. To do a renewal, you will have to go through an entire renewal.

If your card replacement request is approved, your program membership will remain the same.

The only thing you are doing here is getting yourself a new physical card.

Bottom line

Global Entry members shouldn't have to show a physical card to get into the expedited lines. Global Entry has gone paper- and document-free with the help of facial recognition.

Considering the isolated cases we have heard about from members who have been asked to display a card, as well as how the card can help you at the checkpoint if you don't have a Real ID, it's a handy card.

This could be a quick and easy way to get a new one if you haven't seen one in a long time.
