Would it be possible to read a 125khz proximity card and replicate the signal with the same device?

The title really explains it all. I was wondering if there was a way to copy an rfid signal and then use that signal with the same device. Is there a device like that or is it something I could make with a raspberry pi because I also have a bunch of those laying around. Thanks for your help
