Fees: low one-time cost for a card set; free app
A good entry-level option for newcomers who want dependable cold storage with almost zero learning curve. The key caveat is the screenless card model: without an independent display you rely on your phone to show honest transaction details, so buy a multi-card set for redundancy.
What Tangem is
Tangem is a hardware wallet in the shape of a payment card. Founded in 2017, it embeds an EAL6+ certified secure-element chip inside a durable NFC card that you simply tap against your phone to sign transactions, using the free Tangem app as the interface. There is no cable, no battery to charge and, by default, no written seed phrase: the keys are generated on the card and you can buy a multi-card set so a spare card acts as your backup.
How it rates
Value is Tangem's strongest criterion at 9, reflecting a low one-time cost and genuine cold storage with almost no learning curve. The app and UX score 8.5 for how effortless tap-to-sign is, and the security model sits at 8 on the strength of the certified chip. Transparency is the weaker area at 7, because parts of the stack remain closed and you cannot audit the whole system the way you can with fully open-source rivals.
Pricing
You pay once for a set of cards and the app is free, which is the core of that 9 value score. Buying a two- or three-card set rather than a single card costs a little more but gives you the redundancy that the seedless design depends on, and it is the configuration we would steer beginners toward.
The key caveat
The card has no screen of its own, so when you approve a transaction you are trusting the phone app to display honest details. On a compromised phone that is a real consideration. The seedless-by-default approach is also unforgiving: lose every card in your set with no backup and the funds are unrecoverable, which is exactly why a multi-card set matters.
Who should consider it
Tangem is a strong entry point for newcomers who want dependable, pocketable cold storage without cables, apps to configure, or seed phrases to safeguard. Power users who insist on an independent display or full open-source verifiability will find it too minimal. Treat this as guidance on the product, not advice on what to hold.
Overall 8.1 / 10 — the weighted average of the criteria above. How we score →
- + EAL6+ certified secure-element chip embedded in a durable NFC card
- + Extremely simple tap-to-sign UX with no cables or charging
- + Optional multi-card backup instead of a written seed phrase
- + Inexpensive and highly portable

- − App is the sole interface and closed elements remain for parts of the stack
Is Tangem safe?
+
Tangem uses an EAL6+ certified secure-element chip and scores 8 on our security model. The caveat is that the card has no screen, so you rely on your phone to show honest transaction details; on a compromised phone that is a genuine risk to weigh.
How does Tangem work without a seed phrase?
+
Keys are generated on the card and, by default, there is no written seed. You tap the card to your phone over NFC to sign. Backup comes from buying a multi-card set, where additional cards hold the same keys, rather than from recording a phrase.
What happens if I lose my Tangem card?
+
If you own a multi-card set, a backup card keeps your funds accessible. If you rely on a single card with no backup and lose it, the funds are unrecoverable, which is why we strongly recommend a two- or three-card set.
How much does Tangem cost?
+
It is a low one-time cost for a set of cards, with a free app and no subscription, which is why it scores 9 on value. A multi-card set costs a little more than a single card but provides the backup the design depends on.
Is Tangem good for beginners?
+
Yes, it is one of the easiest wallets to use, with tap-to-sign simplicity and almost no learning curve, earning 8.5 on app and UX. Beginners who want independent on-device verification or full open-source code may find it too minimal.
