The Tangem card wallet is a hardware wallet that looks and behaves like a bank card. There’s a secure chip inside, an NFC antenna, and nothing else: no battery, no screen, no port. You tap it on your phone to sign transactions, and it goes back in your wallet. We stock it in Auckland at tangem.nz.
This post is a plain description of what the card is, how it works, and who it suits, for anyone in New Zealand weighing it up against a USB-style device or against leaving crypto on an exchange.
What the Tangem card wallet is
Each card contains a Samsung secure element certified to EAL6+, the same class of chip used in passports and payment cards. When you set the wallet up, that chip generates your private key internally and keeps it. The key is never shown to you, never copied to your phone and never sent anywhere. To spend, the Tangem app builds the transaction, you hold the card against the phone, the chip signs it, and the signed result is broadcast to the network.
The main things worth knowing:
- Bank-card size and thickness, so it lives in your normal wallet.
- No seed phrase by default. Backup is a second and third card that share the same key.
- Firmware audited by Kudelski Security and Riscure and fixed at the factory, so there is nothing to update.
- More than 90 networks and 16,000+ tokens in the app, including Bitcoin, Ethereum, Solana and the major stablecoins.
- IP69K rated, no moving parts, and a 25-year warranty on the chip.
Why people in New Zealand choose it
Most of our customers are moving crypto off an exchange for the first time. The thing that puts them off other hardware wallets isn’t the price, it’s the 24-word phrase and the responsibility that comes with it. Tangem removes that step. You get cards instead of words, and cards are something people already know how to look after.
The second reason is that it doesn’t ask anything of you after setup. No charging, no firmware notices, no cable to find. Scan it once or twice a year to check it, and otherwise leave it alone.
Tangem card compared with a USB hardware wallet
| Feature | Tangem card wallet | USB-style hardware wallet |
|---|---|---|
| Form | Bank card | Small device with screen |
| Backup | Matching cards | Written seed phrase |
| Connection | NFC tap to phone | USB or Bluetooth |
| Maintenance | None | Firmware updates, charging on some models |
| Durability | IP69K, flexible | Plastic housing, battery on some |
| Transaction display | On your phone | On the device screen |
The last row is the real trade-off. A device with a screen lets you check the address on hardware you trust more than your phone. Tangem’s answer is fewer parts and no seed phrase to steal. Which matters more depends on how you use crypto; for most holders the seedless side wins.
How it works day to day
- Order a set from tangem.nz. Two cards or three.
- Install the Tangem app on iOS or Android.
- Tap the first card to create the wallet, then tap the others to link them as backups.
- Set an access code, add your coins, and move a small test amount before the rest.
From then on, sending is: enter the details in the app, tap a card, done. Receiving needs no card at all. The full walkthrough is in our five-minute setup guide.
Security, honestly stated
The chip is the strong part: the key can’t be read out, and the firmware can’t be changed. A lost card is protected by your access code, and the chip locks after repeated wrong guesses. Tangem itself can’t get into your wallet, which also means it can’t help you if you lose every card without having made the optional seed phrase.
What the card can’t protect you from is sending funds to the wrong place yourself. Phishing and fake “support” remain the way most people lose crypto, with any wallet. We cover the practical defences in protecting your crypto from phishing and fake apps.
Who it suits
Anyone who wants their crypto off an exchange and doesn’t want a seed phrase in their life. First-time holders, people buying for a partner or parent, and long-term savers who’d rather not think about the wallet between top-ups. Frequent traders who live in DeFi dashboards may prefer something that plugs into a desktop, though the app’s WalletConnect support covers most of that ground.
