Appropriate nickname... I'd take a picture of my card that is labeled Global Entry, but I feel like that would be exposing myself to personal security/identity issues. It includes the expiration date, date of birth, picture, and on the back has both date of issue and your trusted traveler ID #.

They even give you a fancy metallic protective sleeve for it labeled "trusted traveler" so people don't steal the information encoded in it remotely...

I will say it's not required to use the kiosk, your passport or manual entry of personal info does just fine there, but sometimes it's handy to access TSA Pre-Check if your boarding pass doesn't list it. Edit: Based on the post above mine it looks like SENTRI/NEXUS lanes are where it actually gets used.

But yes, there is a card issued. ^
