PassCards | How we make our flagship password cards

PassCard is, so far, our most popular metal card.

Backed by over 1000 backers on Kickstarter in 2023 (THANK YOU!), we have been able to purchase two industrial-grade laser-engraving machines for our studio to produce your most durable password tool.

PassCard is a metal card that allows you to generate and access different strong passwords for various situations, simply from the graphics on it. There is no electronic component in it, and therefore it is unhackable.

For information about how to use PassCard, please click here to visit its webpage, as this blog is going to talk about how this card is made and how we securely manage the data of all cards.

Producing PassCards is no easy task. Common reference cards in the market usually only have, at most, one side of variable data, and they are very easy to be produced by importing a spreadsheet file into the laser-engraving machine. After engraving one card, the engraver can usually read and engrave the data from the next line of the data file.

However, in our case, every PassCard has two different sides with unique data, and they have to match with each other correctly on every single card according to our database. It means that the usual automation of a laser-engraving machine can no longer be used.

Therefore, during production, we need to generate the graphic file of each side of each PassCard first. Once we have engraved one side, we have to manually change the engraving graphic file to engrave the other side. After that, the file is changed again for another card. Each graphic file is assigned with a unique reference number that we can read on the monitor (just like the serial number on each PassCard), allowing us to make sure we engrave the two sides of a card correctly and we do not produce two cards with the same data. And yes, this process is very painstaking.

Once a batch of PassCards are produced, all its data and its graphics are securely transferred, using TLS/SSL protocol, to our secure separated storage with 256-bit AES encryption.

And this means, when users request the back-up graphics (which is FREE) or order a replacement card with their PassCard serial number, we have to manually look for your card data in our secure storage to process your request. These are not auto processes, so that we can make sure your data is securely isolated.
