Popular questions

What can I do with a Tangem Note?

A Tangem Note allows you to:

  • Check the validity of the Note and the assets it’s holding
  • Transfer funds to other Tangem Notes
  • Extract funds from Tangem Notes
  • Pay with the Note (with merchants currently accepting crypto)

What makes Tangem different?

A Tangem Note is a highly secure hardware cold wallet made to store any kind of digital assets on blockchain technology. With an NFC-enabled phone, you can verify your balance and extract your assets if you want to move them to another wallet.

Each Tangem Note, Tangem Tag or Tangem ID holds a secure chip that allows you to store and carry digital assets. The private key is generated by and permanently embedded into the chip.

Nobody has access to it either during or after the manufacturing process. This means that nobody can import, export or make a copy of this key.

How do I check the validity of a Tangem Note?

If you have ever used Apple or Google Pay, you know exactly how to check the value of a Tangem Note and the amount of funds it’s holding. You just need to open the Tangem app and tap the Note to the NFC scanner inside your phone.

Scanning the Note only takes a few seconds. The app will verify that the Note is genuine, ensure it possesses the correct private key, and obtain the balance from the blockchain. You can always double check your balance directly in the blockchain explorer if needed. From this point, you can rest assured that you are the only holder of the private key and the funds on the Note.

How many times can I use a Tangem Note?

Tangem Notes are fully reusable. There is no limit for transactions or for how many times you perform loading/extraction operations.

Tangem Notes are limitless. You can send as many funds to your Tangem Notes as you want (but we advise not to put more than US$500 or the equivalent for the same reason you don’t carry that much cash with you on an ordinary day).

How can I be sure that Tangem is secure?

The security of Tangem technology is audited by the Kudelski Group, a listed Swiss security company. The full report is available here.

After the audit, the chip firmware cannot be modified even by Tangem. Its intactness in each Note can be verified by an end-user right in the mobile application. The latter exists in open source together with the NFC communication protocol of the Note.
