That is really neat... in regards to physical bitcoins, if you accept them as tender, how do you know someone has not transferred the balance off of them and then you accept a coin with no value? Or do you check prior to accepting? Sorry.. little new on this.

The hologram has a sensitive tamper evident pattern that looks like honeycombs if peeled. I am aware of no way to read the key underneath without exposing this pattern. So if the pattern is intact, the coin is good.
Secondarily, if I peeled the hologram and redeemed the code and were successful, then that is a certain way to know that it was good (though destructive...)
And just to make clear: the number on the outside is just for checking the balance. The number needed for redemption is concealed under the hologram and is much longer than 8 characters.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable. I never believe them. If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins. I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion. Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice. Don't keep coins online. Use paper or hardware wallets instead.

Impressive! But before I order, could you just tell me why the 405 nm laser beam appears red in the photo. Thanks.

Perhaps it isn't swimming backwards, but is using the laser for photon propulsion.

Where are you Texas Laser Systems? Your website is gone, your facebook page is blank, and you haven't posted anything for a year. Just want to make sure you are OK.
