Has anyone used one of these?
I was thinking of using it to copy a parking pass.

Very well known and recommended by many people, I think you can buy it with your eyes closed.
Fun tool! I've been using the Flipper Zero since it was first released. Great for exploring RFID and NFC tags/cards. Do you have specific questions?
To get started with it, I recommend checking out some education videos by Talking Sasquatch and then flashing some custom firmware like Unleashed so you can get access to the full radio spectrum capabilities of the hardware.

Yes, they're good for that. Also, the wifi board and the unleashed firmware open up all kinds of interesting stuff.
I backed the original Kickstarter a few years ago. It's a ton of fun.
I LOVED my old flipper, very useful tool and can definitely do that.
Mine was stolen by a jealous ex-friend and I never replaced it which I regret
