Tangem Wallet 3 Cards Set

The Tangem Wallet 3 Cards Set is a card-shaped hardware wallet. Your private key is generated inside a certified secure element on the card and never leaves it. You sign transactions by tapping a card against your phone. There is no cable, no battery and nothing to charge.

The three cards are not three wallets. They are three copies of the same key, so any one of them opens your wallet.

Why choose three cards over two

• Three copies of your key instead of two. Lose one and you still hold two.
• The third card is what lets you reset a forgotten access code. With a 2-card set, losing one card and forgetting your code leaves you unable to recover the wallet.
• Tangem itself recommends the 3-card set for this reason.

Security

• Secure element certified CC EAL6+, developed with Samsung Semiconductors
• Firmware independently reviewed by Kudelski Security and Riscure
• Firmware cannot be updated, by design. No update channel means no update channel for an attacker to abuse, and there are no hidden algorithms.
• Access code protection, active once the cards are linked to one wallet
• Brute-force resistant: from the sixth incorrect attempt the delay before the next attempt grows by one second each time, up to 45 seconds

Built to outlast the phone you set it up with

• IP69K resistance to dust and water
• Operating range −25°C to 80°C
• Guaranteed for 25+ years
• No battery, so there is nothing to degrade and nothing to replace

Setup and recovery

Tap the cards to your phone in the Tangem app. The key is generated on the card itself and copied across the set, so every card in the set opens the same wallet.

If you prefer a seed phrase, Tangem supports it: you can create a wallet from a 12 or 24-word phrase, or import an existing wallet from a phrase of 12, 16, 18 or 24 words.

Connectivity and compatibility

• NFC. Tap a card to your phone to sign.
• Tangem app available on the App Store and Google Play
• Works with both iPhone and Android

Common questions

Do I need all three cards to use the wallet?
No. Any one card opens the wallet. The other two are backups.

What happens if I lose a card?
You still have access with the remaining cards. Losing every card in the set means losing access to your funds, because only your cards can open the wallet.

Does it need charging?
No. The cards have no battery and draw power from your phone over NFC when you tap them.

Is there a seed phrase?
Only if you want one. The default setup uses the cards themselves as the backup, with an access code you set. Seed phrase creation and import are both supported.

Can the firmware be updated?
No, and that is deliberate. There is no update mechanism, which removes an entire category of remote attack.

What is the difference from the Tangem Ring?
The Ring is a wearable version of the same technology and ships with two backup cards. This set is three cards.

Buying from SIAMBC

SIAMBC is Thailand's authorized Tangem distributor, with a physical store in Bangkok. Every unit is new, sealed and sourced directly. Support is available in Thai and English.

ONE RULE TO REMEMBER

Anyone who asks for your access code, your cards or your seed phrase is a scammer. No exceptions.

Neither SIAMBC nor Tangem will ever ask for them, whatever reason is given — warranty claims, identity verification, system updates or account recovery. Those are the keys to your funds. Whoever has them owns your crypto, and it can never be recovered.
