What is surface treatment of Thin King?

Surface of Thin King is anodized. It’s a really thin coating that enables metal to shine through the colour. It also protects aluminium from oxidising.

This technology is widely used by major credit card companies. There may be differences between countries and market areas.

Skimming and scanning are terms for stealing your credit card information. This usually applies to RFID cards. RFID? Radio-frequency identification (RFID) is the use of a wireless non-contact system that uses radio-frequency electromagnetic fields to transfer data from a tag attached to an object, for the purposes of automatic identification and tracking. This means that a criminal can scan your pockets and steal your credit card information without you even noticing it.

Most of the new credit/bank cards has contactless payment feature for small amounts (NFC=Near Field Communication). Thin King’s cover is made of aluminium, and therefore it blocks any skimming and scanning attempts.

Thin King is safe!

For the same reason you can’t use your travel card ( like Oyster Card in London or Rabbit Card in Bangkok ) without taking it out of your Thin King.

Of course it can! We drove a big van over it without breaking it nor the cards inside it. Thin King’s mechanism has been tested also. Ruthless robot was wanking it 10 000 times back and forth, before it got bored. Mechanism did not changed in time of this brutal process.
