All for one and one for all

At Fidesmo, our philosophy is: why have many devices for different tasks when one can do them all. Payment cards being the perfect example. Together with our partners, we’ve made it possible to connect multiple cards to a single passive wearable, i.e., one where no batteries are needed, so you no longer need any cards or your phone for contactless payments.

Now, we’re making it possible for Tesla drivers to securely connect their car keys and their payment cards to one wearable. So, if you’re a Tesla driver, you can open your car door, start the car, pay for charging, buy a snack mid-journey, or pay for the weekly shopping with a ring, piece of jewelry, watch strap, you name it.

Frequently asked questions

To support page

Are wearable payments with Fidesmo Pay secure?

Yes. When you connect a payment card to your wearable with Fidesmo Pay, a reference of the card is created, a reference with a different card number, this is called a token. This card number can only be used on your wearable – not online or anywhere else – which means that your wearable is protected against skimming and even if the card number would leak on the internet (e.g. if there would be a data leak from one of the stores where you have made a payment) it cannot be used anywhere else. The card number on the wearable is also cryptographically connected to that certain wearable, and the card number can not be added to any other physical wearable that you can pay with. To summarise, wearable payments with Fidesmo Pay are very secure, even more secure than paying with a physical payment card, where that card number can be used both when paying in-store as well as online.

Can I pay with Fidesmo Pay in any country?

Yes, as long as the terminal supports contactless payments. Just like you can tap and pay with your payment card at any contactless terminal around the world, you can tap and pay with your wearable.
