  • What is Tangem Wallet?

    Tangem Wallet is the safest hardware wallet in the world. Tangem Wallet keeps thousands of cryptocurrencies simultaneously and has access to hundreds of decentralized financial services for buying, selling, exchanging, staking, and lending.
    The card is the key to your wallet, and using your funds requires bringing the card to your phone.
    Tangem Wallet is a set of 2 or 3 cards with a backup feature. So when activating a card, you can back up the key on the other card(s), which will help you manage your money even if you lose one of the cards, and enabling the access code will prevent your funds from being transferred by an attacker in case of loss or theft. 

  • What is Tangem Note?

    Tangem Note is the most straightforward single-currency hardware wallet for your six beloved cryptos: BTC, ETH, BNB, XRP, ADA, and DOGE.

    Tangem Note allows you to buy, store, sell, and transfer cryptocurrencies on its native network in just a few taps. Or you can hand your Tangem Note with the required amount in exchange for goods or just as a gift — just like a regular paper banknote. If you want to invite your family or friends to the world of crypto — Tangem Note is a perfect choice.
    No one except the owner has access to the wallet. The card generates a unique key while activated in the Tangem app by the user. The key always remains on the card and is unknown to anyone, including Tangem.

    Our cards can sign an infinite number of transactions. You only need an NFC smartphone, the Tangem app, and your Tangem Note.

  • What can I do with Tangem Wallet?

    Tangem Wallet allows you to:
    — check the validity of the card and the assets it's holding;
    — show the asset's blockchain address;
    — extract (send) funds to other Tangem cards or blockchain wallets;
    — pay with the card (with merchants currently accepting crypto).

  • Can I pay with my Tangem card at physical stores?

    Tangem cards are not payment cards like Visa or Mastercard. If a seller supports the transfer in cryptocurrency, you will be able to transfer funds to their address and pay for the goods or service. But if you mean using a card by analogy with a bank card, then it is not supported yet.

  • What makes Tangem cards different from other cold wallets?

    Tangem Wallet is the world's most secure, as evidenced by Common Criteria EAL6+ chip certification and a firmware audit by Kudelski Security. It's the only hardware wallet in the world with an IP68 environmental protection rating. When you create a wallet, while your phone scans the card, a private key is generated on the card, which does not leave the card afterwards. This eliminates the possibility of disclosing the key to third parties - it is stored exclusively on the card chip and is not known to anyone. Not even the owner of the wallet.

  • What are the iOS/Android technical requirements to use Tangem cards?

    You can use any mobile device with an Android operating system higher than 5.0 or iOS 13 and higher that has full NFC support, except iPhone 6/6s.

    Please note that the iPhone 7/7 Plus and some Android models do not have full NFC support, which does not allow you to transfer the required amount of information during activation. In this case, making a backup of a private key on your phone is not available. But you can use any other phone (iPhone 8 and up or Android 5.0+ with full NFC support) to create a backup and then continue using your device.

  • Is it possible to use the wallet with a PC or tablet?

    No, as the tablet and PC do not have an NFC module. You can use any NFC-enabled Android or iOS mobile device except the iPhone 6/6s.

  • Why can't I download the Tangem app from Google Play?

    Most likely, your Android device does not have full NFC support, so the app cannot be downloaded from the market. In such a situation, you should use any other device (iPhone 8 and up or any Android 5.0+ with full NFC support).

  • Where can I download an APK file for Android?

    You can download the APK file from GitHub and install it on your phone by the link.

  • How many times can I use my Tangem card?

    Tangem cards are fully reusable. There is no limit to transactions or how often you perform loading/extraction operations.

  • How much can I store on my Tangem card?

    Tangem cards are limitless. You can store as many funds on your Tangem card as you want.

  • What's the difference between a 2-card set and a 3-card set?

    The only difference is the number of cards. Additional cards are needed to create a backup. How many cards you have in a backup (2 or 3) as many copies of your private key exist in the world. If one of the cards is lost or stolen, the backup cards will help you restore access to your wallet.

  • Can I use all three cards for different wallets?

    You can use all three cards as three separate wallets. Please keep in mind if you lose one of these cards, you will lose access to your wallet. So, we recommend that you create backup copies on additional cards. This way, if one of the cards is lost or stolen, the backup cards will help restore access to your wallet, and the access code will help prevent an attacker from transferring your funds.

  • Can I use one wallet on multiple devices?

    Yes, you can use the wallet simultaneously on unlimited devices. The phone itself doesn't store any assets you are holding; it only acts as a display by visualizing specific data for a particular user via its screen. Storage of private keys and signing transactions are performed by your card.

  • What are the differences between Tangem Note and Tangem Wallet?

    In contrast to Tangem Wallet, Tangem Note is a single card, so it has no backup function and no access code protection.
    Tangem Note is a good choice for beginners in cryptocurrency, as well as for a gift or hand-to-hand crypto transfer.

  • What is the difference between a white Tangem Card and a black Tangem Wallet card?

    The black Tangem Wallet cards are a newer product. Both white and black Tangem Wallet cards support the same number of networks and tokens (except Solana tokens on the white card). There is no backup option on the white cards, hence no additional access code protection. 

  • Where is the company registered?

    Tangem is registered in Zug, Switzerland.

  • When did the first cards appear on the market?

    In 2017-2021 Tangem mostly worked on the B2B market (for example, we supply cards for the popular XRPL wallets XUMM). Tangem moved to the B2C market under its brand at the end of 2021, and that's when Tangem Wallet appeared.

  • Where can I find out about news and updates to the wallet?

    Stay tuned for the latest news of Tangem on our Telegram channel.

  • What is the difference between the series of cards?

    ACxx is just a production batch. Tangem produces the cards in batches, and as soon as it runs out of stock, it produces more. There is no functionality between batches, so there is no cause for concern as they are identical.
