Why Safedome is wafer thin

Posted on November 17 2015

One of our most incredible (and toughest) journeys was deciding to take our 3mm thick prototype and thin it down to credit card size. “Can’t be that hard,” we joked at the time. Turns out, thinning it down to under half its original size took probably ten times more effort and time than we expected. It involved new manufacturing processes and working with miniaturisation experts.

In the end we faced three big problems. If you’re into the tech behind Safedome or just interested to know why this card is so perfect for humans, keep reading…

Why we made Safedome wafer thin

No one wants more clutter in their life.

We wanted Safedome to be a product that fitted your life, not the other way around. Thinning it down to roughly the same size as a credit card, however, was not going to be easy. 

To make a product thin enough to slip into your wallet with the rest of your cards, we had to find the right technology partners to work with. And there aren’t many, trust us. The battery and electronics in the card you hold in your hand today are the smallest in the world – and are mounted on paper-thin board, which is as fragile as rice paper. 

Today’s products must handle whatever life throws at them.

Think about how hard a time your bankcards have. You squeeze them into your back pocket, sit on them, leave them in the sun, in wet bags, and spill coffee on them. They need to bend, stretch and distort – and continue to perform every day. So of course we wanted Safedome to do the same. We underwent test after test after test to make sure Safedome was durable; so you don’t have to ever worry about your Safedome card.

Who has time to charge another device?

Life is busy. Try to imagine how many times you would have to charge the battery on your phone if you continuously talked on it for an entire year. A lot. Now while the Safedome card only uses a tiny slither of the power used by your phone, this is the problem we faced. A problem no one has time for.

Our solution? New Bluetooth Low Energy technology. It only uses a small portion of the energy used by earlier Bluetooth protocols. 

We also had to tightly integrate the phone’s operating system, the card’s firmware, and our application. Lots of testing, many rewrites, more code, late nights and lots of frustration. But we did it. And now you don’t have to do anything. 

The card you see today.

In the end we got there. And while we will continue to optimize, together with our partners we managed to solve these three big problems. What next, you ask? You’ll just have to wait and see. But it will be exciting.
