I am overjoyed to see this story here, we haven't gotten a lot of these hacks lately. Well done!

Hacks? In my Hacker News? The nerve!

Are these hacks or cracks. I'd say the latter.

I wouldn't. It doesn't appear that anything was cracked. Rather they just reverse engineered the protocol.

That's a crack, but repurposing price tags to display things they weren't intended to is a hack.
