Tangem Bit card

Hello Hunters 👋, Sergio, Andrey, Michael and Grecia here! Bitcoin gives users individual choice and control over financial and personal data, making it a powerful financial industry asset. However, today, owning and managing Bitcoin is not accessible to everyone in the world. Getting onboard is historically very complicated. Most of the products to store and use Bitcoin require being tech-savvy and imply long and complicated steps for a newcomer. Therefore, we’re excited to introduce Tangem Bit, an easy to use, and affordable wallet that makes it easy for anyone to send and receive Bitcoin securely. How does it work? As a result of many years of advanced chip and firmware research, our chip generates and stores your private key within the card itself. NFC generates enough power to operate the chip. Thanks to those qualities, all you need to do is tap your Tangem Bit card on a smartphone. No need for complicated initialization ceremonies 😀. Who can use this Bitcoin wallet? Everyone! At Tangem, we believe that Bitcoin should be accessible to everyone and decided to make the process fun and straightforward.

Thanks for the support, and please don’t hesitate to leave a comment or reach out to us directly.

Ok, does the card perform anything else other than sign what a (third party, at a retailer) wallet tells it to? How does the user verify that the retailer isn't lying (by overcharging him or displaying the wrong balance when asked, etc).

I'm so excited to find Tangem in Product Hunt! I first knew about Tangem last year at Stellar Conference I still have those cards :) This is one of the most promising products in the industry as it's one of the easiest ways to make crypto portable. Good luck guys!

Incredible solution. We are anxiously waiting for it to arrive in Argentina. In economies like ours, these solutions give hope. They make the portability of cryptocurrencies easier. Congratulations!

I really love it! Congratulations!

Tangem is great. This is the cash of the future. Cash and a bank account rolled into one, all in an easily usable format. A great solution for tangible, secure bitcoin storage too. Looking forward to experimenting with Tangem wallets for my security token bonds as well.

I have been using these cards for over a year now and they are nothing short of revolutionary! At first I just thought they were cool but after having them and exploring what’s possible there is so much. They are the perfect solution for gifting crypto to others: I’ve used them as prizes in scavenger hunts. I even made a piece of art with them that serves as a physical faucet...it’s pretty wild. All this to say these are fantastic and you should definitely get a couple to test out and to use.
