Main Takeaway: For most people comparing an NFC card cold wallet in 2026, the ELLIPAL X Card is the one to get. It follows the BIP39 standard, so your seed phrase restores on any compatible wallet from any brand, and it generates that seed offline on the X Card Starter so the phrase never touches an internet-connected device during setup. It supports a BIP39 passphrase, ships in multi-card setups of up to 10 cards each with an independent PIN, and pairs with the ELLIPAL App you already use. Tangem is a well-built card, but its seedless design binds the keys to Tangem cards alone, which is the single decision that shapes everything else. This guide explains what the X Card does differently and why it fits more people.

The short version
Both the ELLIPAL X Card and Tangem are NFC card cold wallets: thin cards that hold a private key in a certified secure element and sign transactions by tapping the card to a phone. The difference that matters is portability. The ELLIPAL X Card follows the BIP39 standard, so the seed phrase you back up at setup can restore your wallet on any BIP39-compatible wallet from any brand, at any time. Tangem's default mode is seedless, which means there is no BIP39 phrase and the keys stay bound to Tangem's own cards, with no restore path to another wallet. For anyone who wants to keep the option of moving their keys later, the X Card is the card that keeps that door open.
What makes the ELLIPAL X Card different
Offline seed generation through the X Card Starter
The ELLIPAL X Card generates your seed phrase offline on the X Card Starter, a companion device used during setup. The phrase is displayed once on the Starter, never stored on the card, and never entered into an internet-connected device during generation. You write it down and back it up yourself. This matters because where your seed is generated determines who could have seen it: a seed generated offline on a dedicated device has a smaller exposure surface than a seed generated inside a phone app, even one in airplane mode. The X Card holds only the private key, not the seed phrase itself.
BIP39 portability, and a passphrase on top
The ELLIPAL X Card is fully BIP39 compatible. A 12 or 24 word phrase from MetaMask, Trust Wallet, Phantom, Ledger, or Trezor imports onto the X Card, and an X Card seed restores on any of those wallets in turn. You are not locked into ELLIPAL for the life of the keys, which is the point: self-custody should mean you can leave whenever you want. The X Card also supports a BIP39 passphrase, an optional extra word that creates a separate hidden wallet on top of the standard seed. Tangem's BIP39 mode does not support a passphrase, and its seedless mode has no BIP39 phrase at all.
Up to 10 cards, each with an independent PIN
The ELLIPAL X Card multi-card setup ships in batches of up to 10 cards, and each card carries its own independent PIN. That fits real backup and access patterns: one card for daily-carry, one card in a safe deposit box, one card for a spouse or a family member, each protected by a different code. Tangem's card set is capped at 3, and those cards share a single PIN across the set. If you want more than three access points, or you want each holder to have their own PIN, the X Card is the setup that scales to it.
ELLIPAL X Card vs Tangem, compared
Both cards use a CC EAL6+ secure element, the same certification grade used in passports, so the chip-level protection is comparable. The differences are in what the architecture lets you do afterward:
- Portability: The ELLIPAL X Card follows BIP39 and restores on any compatible wallet brand. Tangem's default seedless mode keeps the keys bound to Tangem cards, with no restore path to another wallet.
- Seed generation: The ELLIPAL X Card generates the seed offline on the X Card Starter. Tangem's BIP39 mode generates the seed inside the phone app.
- Passphrase: The ELLIPAL X Card supports a BIP39 passphrase for a hidden wallet. Tangem does not.
- Backup scale: The ELLIPAL X Card set goes up to 10 cards with independent PINs. Tangem caps at 3 cards on a shared PIN.
Which one fits you
If you already use MetaMask, Trust Wallet, or Phantom
The ELLIPAL X Card is the natural upgrade. Import your existing BIP39 seed onto the X Card through the offline Starter, and your same accounts move to cold storage with the private key now held in a CC EAL6+ secure element instead of in software on your phone. Nothing about your addresses changes.
If you already own a Ledger or Trezor
The ELLIPAL X Card gives you a card-format daily-carry option that speaks the same BIP39 language your existing wallet uses. You can run the X Card alongside your current device, or import the seed and consolidate, since the standard is shared across all of them.
If you want daily convenience and portability in one card
The ELLIPAL X Card is built for this. Tap to sign, 3-minute setup, battery free, 1.2mm thin, and a seed that stays portable across the whole BIP39 ecosystem. You get card convenience without giving up the ability to move your keys later.
If you are setting up backups for family or multiple locations
The ELLIPAL X Card multi-card setup fits directly: up to 10 cards per batch, each with its own PIN, so every location and every family member has independent protected access. This is the scenario where Tangem's 3-card shared-PIN cap is most limiting, and where the X Card was designed to scale.
The seedless tradeoff, and why it matters
Tangem's seedless model offers its own recovery method through additional cards and points to open-source software. For an everyday user, though, the harder question is what happens on a bad day. If the Tangem software has an outage, a compatibility issue, or the company behind it stops operating, a seedless setup gives an ordinary user no immediate way to move their crypto out, because there is no BIP39 phrase to restore the keys on another wallet. The keys stay bound to the Tangem cards.
An ELLIPAL X Card user does not carry that worry. Even in an unexpected situation, whether a software problem or a company-level disruption, the X Card user can restore their crypto anytime, anywhere, on any BIP39-compatible wallet using the seed phrase they backed up at setup. Your access to your own assets does not depend on a single company staying online. That independence is the whole point of a portable seed, and it is why the ELLIPAL X Card is the recommendation here.
FAQ
Is the ELLIPAL X Card better than Tangem?
For most use cases, yes. The X Card follows BIP39, so your seed restores on any compatible wallet from any brand, while Tangem's default seedless mode binds the keys to Tangem cards alone. The X Card also generates the seed offline on the X Card Starter, supports a BIP39 passphrase, and scales to 10 cards with independent PINs where Tangem caps at 3 on a shared PIN. The one case where Tangem fits better is if you specifically want no seed phrase at all and are content to stay within a single vendor.
Can I move my existing recovery phrase to the ELLIPAL X Card?
Yes. The X Card is fully BIP39 compatible, so a 12 or 24 word phrase from MetaMask, Trust Wallet, Phantom, Ledger, Trezor, or any other BIP39 wallet imports onto the X Card through the offline X Card Starter. Your accounts and addresses come with it, since they are derived from the seed itself.
Where is the seed phrase stored on the X Card?
It is not stored on the card. During setup, the seed phrase is generated offline and displayed once on the X Card Starter. You write it down and back it up yourself. The card holds only the private key, not the seed phrase, so the phrase exists only on your offline backup.
How many backup cards can the X Card have, and do they share a PIN?
The X Card multi-card setup ships in batches of up to 10 cards, and each card has its own independent PIN. This fits family, team, and multi-location backup patterns where each holder needs separate protected access. Tangem's card set is capped at 3 cards on a shared PIN.
Does the X Card support a BIP39 passphrase?
Yes. The X Card supports an optional BIP39 passphrase, an extra word on top of your standard seed that creates a separate hidden wallet. Tangem's BIP39 mode does not support a passphrase, and its seedless mode has no BIP39 phrase to add one to.
What happens if I lose my X Card?
Your crypto stays safe as long as the seed phrase you wrote down at setup is intact. Restore it onto a new X Card, or onto any other BIP39-compatible wallet, and your accounts return. If you used a multi-card setup, the remaining cards, each on their own PIN, are unaffected by the loss of one.
Are both cards using the same kind of secure chip?
Yes. Both the ELLIPAL X Card and Tangem use a CC EAL6+ secure element, the same certification grade used in passports. The chip-level protection is comparable, so the meaningful differences are in portability, seed generation, passphrase support, and multi-card scaling rather than in the chip itself.
The bottom line
The ELLIPAL X Card and Tangem are both credible NFC card cold wallets on comparable secure-element hardware. The decision comes down to what the architecture lets you do next, and on that axis the ELLIPAL X Card is the more flexible card: BIP39 portability so you can move your keys to any wallet brand, offline seed generation on the X Card Starter, a BIP39 passphrase for a hidden wallet, and up to 10 cards with independent PINs for real backup patterns. For most people comparing the two in 2026, the X Card is the one that keeps your options open while giving you the same tap-to-sign convenience. That is why it is the recommendation here.
Own it. Then use it.
Security note: No self-custody setup removes every risk. NFC cold wallets close many remote network attack paths but do not eliminate physical, supply-chain, firmware, social-engineering, or user-error risks. Buy from an official source, store your recovery phrase on a durable offline backup kept separately from the card, do not share or digitally enter it, and verify every transaction on your phone before tapping.
