Hey guys!

thanks for all the interest! So I tested the cards with a blow torch today, and will post a video once I get iMovie working. For those who cant wait for the results:

After being blow torched for ~2 mins, with the flame held only a few inches from the card, the red anodizing was stripped from the card. Although anodizing was no longer present, the IDs that had been engraved were still perfectly legible. The QR code had a tough time reading. I assume this was because there was not enough contrast between the now silver card, and the engraved QR code. This would mean you would have to manually type in your codes after it has been in a fire.

Overall, were happy with the results, as it shows that the engraving is on the aluminium it self, and if the anodizing is stripped (in this case, completely) the card is still readable. Keep in mind, we are not claiming these cards to be fire proof, and this test was just done out of curiosity! When buying these cards, just think about what kind of stresses they will realistically have. If you think fire is a serious problem for your cards, I would suggest getting two, and storing them in separate places.

Note: If you are seriously interested in a completely fire proof card, send us a PM, as we do have the capabilities to make a black, fire "proof" card, but will only do so if there is a demand for such a product.
