According to Cointelegraph:
Since 2018, Tangem has manufactured over 1,000,000 cards and has never been hacked—a remarkable achievement in the cryptocurrency industry. Additionally, many users appreciate Tangem’s quick 3-minute setup time and unparalleled digital asset security. So, what exactly is the Tangem Wallet, and how does it work?
What is Tangem Wallet?
Tangem Wallet is a non-custodial cold wallet that uses a powerful secure element chip developed in collaboration with Samsung Semiconductor. Tangem Wallet offers a variety of features, such as conveniently storing, buying, selling, sending, receiving, and exchanging multiple cryptocurrencies, and accessing DeFi and dApps. Here is a brief explanation of how it works.
How does Tangem Wallet work?
Tangem Wallet consists of two main components. One component is the hardware wallet device—two to three physical Tangem cards. The other component is the Tangem mobile application, available on iOS and Android platforms. Tangem cards and the application communicate via Near Field Communication (NFC), a wireless technology for close-range device interaction through magnetic field induction.
