I’ve been looking into NFC card-style cold wallets recently, and honestly, I think this category is much smaller than it first appears.
A lot of products get grouped into the same “card wallet” discussion, but they’re actually pretty different:
- CoolWallet Pro = more of a card-shaped Bluetooth wallet
- SafePal X1 = handheld air-gapped device
- Arculus = premium NFC metal card, but more limited ecosystem
- Tangem and ELLIPAL X Card = the two that seem closest to the actual “NFC card cold wallet” idea
For me, the real difference is not just NFC tap-to-sign. It’s how the seed phrase is handled.
Tangem
- very simple setup and backup model
- closed multi-card backup is appealing for convenience
- if you use the seed phrase option, it’s generated/displayed through the phone app
ELLIPAL X Card
- same NFC card-style experience
- supports BIP39
- uses the offline Starter device for seed phrase generation/import/viewing
- seems more appealing if you care about keeping the seed workflow fully offline
So the tradeoff looks pretty clear to me:
- If you want simplicity and don’t mind a more closed model, Tangem makes sense.
- If you want BIP39 portability + fully offline seed handling, X Card seems like the stronger design.
That’s how I’m seeing it right now.
Curious what others here think:
For a card-style cold wallet, do you care more about simplicity, or about offline seed phrase purity / portability?
Am I wrong, or are X Card and Tangem basically the only real NFC card cold wallet options?
