In this article I will introduce you to a Karatbars gold card and its features.
All gold bars produced by Karatbars are embedded into plastic cards similar to credit and debit cards issued to you by banks.
Each card and a bar itself are covered by a layer of durable anti-scratch laminate. Anti-scratch feature in laminate was not there at the beginning, however. It was added after noticing that previously used laminate had a tendency to peel. Harald Seiz, a founder of Karatbars, took this matter into his own hands and soon the new type of laminate, resistant to most scratches, was developed. Today, gold cards are sealed with this laminate right in the Karatbars corporate offices using special machines!
Have a look at a Karatbars gold card below – at its front and back sides. I made these photos with the phone, so the quality may not be the best.
Karatbars small gold bars come with 3 security features
A Karatbars gold card has no analog on the market.
No other company carries gold with three security features located all on a single card.
In fact, out of all companies producing LBMA gold in small denominations, only Argo Heraeus and UBS have a security feature on their cards. Only one security feature! A hologram. That is it.
In contrast, each Karatbars gold card has a total of three security features! They are: a hologram, the unique Karatbars DNA and the blacklight signature.
Let’s start with a hologram.
A hologram is one of three security features found on a Karatbard gold card.
The hologram is applied onto the plastic of the card and covered with the laminate on top.
In general, holograms are extremely difficult to forge because they are copies of an original hologram image or a so called master hologram. To make a master hologram, you need a highly specialized optical equipment.
When you look at the Karatbars hologram and move it at different angles, there will be an instant when the light is diffracted (or bended) in such way that Karatbars “K” appears. You can see it on the above photo.
Besides being a security feature, the Karatbars hologram also adds an interesting visual effect to the card.
Now, moving to the blacklight signature.
The blacklight signature is the second security feature on the card.
You should be able to see the blacklight signature if you shine light on the front side of the card with a blacklight flashlight. Precisely, Karatbars logo in purple should come up.
Blacklight is a type of ultraviolet light. For your reference, a source of such ultraviolet light is plain sunlight.
Finally DNA, or the unique Karatbars DNA.
Unique Karatbars DNA
The unique Karatbars DNA is a third security feature of the card.
Each bar is “bathed’ in unique Karatbars DNA during the manufacturing process.
Similar to the blacklight signature, you cannot see the Karatbars DNA with the naked eye. The signature can only be read by a special device, the Karatbars SDNA-ID reader.
Similarly, all features shown and discussed above are also found on 2.5 gram and 5 gram Karatbars gold cards.
I am sure you got the point. Whoever wants to forge a Karatbars gold card has tons of work to do!
What does it mean for you? It means that you don’t have to worry about the authenticity of any Karatbars gold card that crosses your path. Ever.
