Pallium Slate Review
Best slim everyday carry
of 10
The Slate is a card-shaped cold wallet you can carry every day and sign with an NFC tap. The lack of an on-device screen is a real trade-off for verification, but for small everyday balances the portability is compelling.

Scores
Pros
- Credit-card form factor fits in a wallet
- NFC tap-to-sign works with the mobile app
- Low price with a clean, ad-free companion app
Cons
- No screen means you verify on the phone, not the device
- Card battery is not user-replaceable
Overview
The Pallium Slate rethinks the hardware wallet as a credit card. It has no cables and no screen; you tap it to your phone over NFC and the secure element inside signs the transaction. It slips into a wallet or passport holder as easily as a bank card.
Fees & costs
At $69 it is inexpensive, and the companion app is clean with no forced swap markup. You pay only network fees. The card is powered by the phone's NFC field, so there is no battery to charge, though it also means no independent display.
Security
The Slate uses an EAL6+ secure element, strong for its price, and keys never leave the card. The important caveat is verification: because there is no screen, you confirm the destination address on your phone, which malware could in principle alter. That makes it best for smaller balances rather than a life-savings vault.
Who it's for
Choose the Slate if you want cold-storage security in a form you will actually carry, for spending-money amounts. For large holdings, a device with its own screen for independent verification is the safer choice.

Frequently asked questions
Does the Pallium Slate have its own screen?
No. It relies on your phone's display for verification, which is convenient but means you trust the phone to show the correct address.
How does it get power without a battery?
The card is powered by your phone's NFC field during a tap, similar to a contactless payment card, so there is nothing to charge.
