GoldCard Reader 101

A question of curiosity. If you post an image of your Gold Card online with the chip visible, can someone reverse engineer codes from the image, as if it were a QR code for a Bitcoin private key, or is it considered completely safe for everyone to see your Gold Card?
From what I remember you need a sequence of three generated keys to be able to generate new ones yourself. When you had issues with the keys (internet connection being bad, ...) the card went out of sync with the servers. Then support asked you to send some keys so they could make it synced again.

Due to that I'd say that the card itself doesn't tell much, rather keep the keys to yourself.

2FA works differently.
