One solution to this problem is the Tangem hardware device: an innovative cryptocurrency wallet that provides a high level of protection through the use of smart cards.

In our review of the Tangem hardware wallet, we will look at

• How this device works and what its benefits are.
• How to use Tangem smart cards for cryptocurrencies.
• What possibilities Tangem offers for integration with mobile devices.

History of creation and development of Tangem 

Tangem was founded in 2017 in Switzerland. The main goal of the development team, which included experts in hardware security and cryptography, was to create an innovative and as simple as possible solution for storing cryptocurrencies, eliminating the risks associated with software wallets. Initially, the company focused on providing a high level of protection and the best user experience through the use of smart card technology and NFC.

Over time, the brand has actively developed, expanding the functionality of its devices and entering the international market. Tangem received support from major investors and partners in the crypto industry, which allowed the company to strengthen its position among manufacturers of hardware devices for storing digital assets.

Today, the company’s products are widely distributed around the world. Tangem actively competes with brands such as Ledger and Trezor, offering users an alternative vision based on smart cards. The company continues to grow its staff and develop new technologies, strengthening its position in the crypto asset cold storage solutions segment.

How Tangem works: smart cards for cryptocurrencies 

It is a hardware wallet for storing cryptocurrencies, designed in accordance with all international security and cryptography standards. Unlike traditional hardware solutions, it is made in the form of a compact card with a built-in chip that provides reliable protection of private keys. 

One of the key features is the use of NFC technology, which allows interaction with mobile devices without wires and additional connections. 

Main principles of the Tangem wallet for bitcoin and ethereum:

• The security of cryptocurrencies with Tangem is ensured by the fact that private keys are stored in the secure chip of the card and cannot be extracted or copied.
• An original mobile application is used to interact with the device to perform transactions, check balances and manage assets.
• NFC connectivity ensures instant connectivity and no need for complicated settings.

Cryptocurrencies supported by Tangem wallet

The smart card supports 81 blockchain networks and thousands of different cryptocurrencies and tokens, including Bitcoin (BTC), Ethereum (ETH), Solana, Binance Coin (BNB), USDT, USDC and many more. A full list of supported assets is available in the app.

Tangem Wallet: Pros and Cons 

Why should you choose Tangem to store cryptocurrencies? What features of this device can be a deciding factor when choosing this hardware solution? 

The advantages of Tangem for secure cryptocurrency storage combine comfortable use and a high degree of protection. A review of Tangem’s features and functions confirms its reliability and convenience.

• Convenience. It is provided by the compact size of the smart card, similar to a bank card. The wallet does not require wires or additional devices to connect to a smartphone. 
• No mnemonic phrase. The unique architecture eliminates the need to write down or memorize a seed phrase, instead using a secure chip that directly stores private keys and prevents their leakage.
• Tangem’s high level of security for cryptocurrency smart cards. The smart card is equipped with a secure chip with EAL6+ certification to store private keys. There is no way to retrieve them. Unlike software solutions that allow users to view, export or write private keys, this device securely encrypts them inside the card chip. This greatly reduces the risk of compromise.
• Durability and reliability. The card is resistant to wear and tear, moisture, and physical damage by using a durable plastic composite and a built-in secure chip. The card is designed to last 25 years.
• Reusable and transferable. The card can be transferred to another user without risk of compromise because the private key remains in the secure chip. The new owner can begin using the card without transferring any data, making the transfer secure and convenient.
• DeFi integration. The smart card offers interoperability with various decentralized financial tools. Through integration with Wallet Connect, users can connect to a variety of DeFi applications.

The disadvantages of this hardware solution inсlude the following characteristics:

• No default PIN (manual activation required).
• Somewhat limited functionality compared to some other hardware wallets.
• Inability to restore access without backup cards. If a user loses their media, they will not be able to restore access to their cryptocurrency unless they have previously created a backup (using additional cards with the same keys). 

Tangem vs. Traditional Hardware Wallets 

Convenience 

The wallet is in smart card format, making it much more compact and convenient than standard hardware solutions such as Ledger or Trezor, which are designed as USB devices. This design makes it easy to carry the small, flat media in a purse or pocket without risk of damage.

Connectivity technology 

Unlike most hardware wallets that use USB or Bluetooth, this solution uses NFC technology to provide an instant connection to your mobile device without the need for wires or batteries.

Security and storage 

The smart card requires no recharging because it does not use batteries, and its case is made of durable materials to protect it from physical damage. Unlike USB devices that can fail due to mechanical connectors, Tangem has a one-piece design that increases durability.

Affordable cost 

Compared to traditional hardware wallets, the cost of Tangem is lower, making it accessible to a wider audience. This is especially important for users who want to store cryptocurrency securely but aren’t willing to pay a high price for premium devices.

Mass-market application

The smart solution can be used not only as a personal wallet, but also for retail and mass cryptocurrency transactions. For example, the cards can be used to distribute cryptocurrency among users, make payments or distribute bonus assets.

Where to buy Tangem smart cards 

You can buy this hardware wallet from the company’s official website, as well as from authorized resellers and marketplaces, such as Amazon and other specialized stores.

Different types of smart cards:

• Standard cryptocurrency storage cards — suitable for personal use.
• Multi-card sets — contain multiple cards with the same keys for backup purposes.
• Special editions — cards with a unique design and limited edition.

When choosing a card, it is important to consider the needs of the user: for added security, it is better to purchase a set of multiple cards to eliminate the risk of asset loss.

How to restore access to the Tangem wallet

When choosing a card, it is important to consider the user’s needs: for added security, it is better to purchase a set of several cards to eliminate the risk of losing assets.

Tangem does not use a traditional seed phrase for recovery. Instead, you must use additional cards containing identical keys to secure access. Then, if you lose access, all you have to do is tap the backup card on your smartphone. 

If you lose the card without a backup, it will be impossible to restore access because private keys are not copied to cloud services or transferred to third-party devices.
