This is really cool. I've been looking at using those dog tag stations you see in malls and walmart entrances. Anybody think this is a bad idea?

Walking around with your seed phrase, entering your seed words in the engraving machine, and waiting for the words to be engraved seems like taking a big risk.
Plus, I'm not sure of the medium they'd use for the tags, and if it'd be durable enough.

I've been thinking about counter-tactics for that, like only entering part into each individual engraving machine. Obviously, I wouldn't keep the tags on me; more likely in the back of a vault.

OK, but you should keep in mind:
  • Entering the first 4 letters of a word is enough to find the word - that's a property of the BIP39 word list, the most common standard for seed phrases these days.
  • Each machine could have a cache, or a log of what's been engraved. And the shop could get your seed words that way. Then, I think it'd be quite easy to brute force the correct order. Maybe you can go to several shops to mitigate that risk...
Seems to me there are better ways to engrave, either with a letter punch as I use for my sets, an engraving pen, or a rotary tool. With these tools, you don't enter any word anywhere with the help/assistance of anyone, but by yourself, on your durable medium.
