Pairs well with
OneKey Lite is a credit-card-sized backup card for your recovery phrase. It keeps the phrase on a chip instead of on paper. When you need to restore your wallet, you tap the card against the device and enter your PIN, with no words to type at all.
What it works with
OneKey Lite works only with the OneKey Pro and the OneKey app. Other hardware wallets are not supported, including the OneKey Classic 1S.
If you use Trezor, Ledger, Tangem, SafePal or another brand, this card will not work with your device.
How it works
Open the OneKey app, choose to back up your recovery phrase, tap the card against the back of your phone and set a PIN. That is all: the recovery phrase is written to the chip inside the card.
On the day you need your wallet back, open the app, tap the card and enter the same PIN, and the wallet is restored. There is no typing the words one at a time, which is where people most often make mistakes and lose the most time.
Security
- EAL 6+ secure chip. A certification level for chip security; the higher the number, the tougher the penetration testing it has passed.
- Wipes itself after 10 wrong PINs in a row, so nobody can keep guessing the PIN.
- Tamper-evident packaging that shows if anyone has opened the box before you.
- PIN protection. Anyone who finds the card cannot read the recovery phrase without the PIN.
Built to last
The card is waterproof and resists being torn by hand. Soaking it in water does it no harm, unlike paper, which one encounter with water can ruin.
The OneKey app it works with
- Supports more than 30,000 digital assets
- Runs on macOS, Windows, Linux, iOS and Android, plus a Chrome extension
- Open source, with ongoing code audits by SlowMist
- OneKey is ISO/IEC 27001 certified
Common questions
Does it work with Trezor or Ledger?
No. OneKey Lite works only with the OneKey Pro and the OneKey app.
Does it work with the OneKey Classic 1S?
No. It supports only the OneKey Pro and the OneKey app.
How is it different from a steel recovery phrase plate?
A steel plate keeps the recovery phrase as letters you can read with your own eyes. It resists fire and water, and you can read it without any device. OneKey Lite keeps the phrase on a chip that needs a PIN and the OneKey app to read.
The card is fast and leaves no room for typos. The steel plate is not tied to any one manufacturer. Many people use both.
If I lose the card, is my money gone?
No, as long as your wallet still works normally or you keep your recovery phrase somewhere else. The card is one more backup route, and whoever finds it cannot read the data without the PIN.
How many wallets can it hold?
One card holds one recovery phrase. If you have several wallets to back up, you need a separate card for each.
One rule to remember
Anyone who asks for your recovery phrase is a scammer. No exceptions.
Neither SIAMBC nor OneKey will ever ask for it, whatever reason is given: warranty claims, identity verification, system updates or account recovery. Your recovery phrase is the key to your funds. Whoever has it can take them at once, and they can never be recovered.

Return and Exchange Policy
Faulty on arrival: if a device arrives defective — a broken screen, a connectivity fault — we replace it with a new one straight away. No forms, no waiting on the manufacturer.
Warranty: hardware wallets carry a 1-year warranty, and claims are handled by us rather than an overseas support queue. CryptoSafe steel backup products are sold without warranty, as stated on those product pages.
Change of mind or wrong model: we do not accept returns or give refunds, whether or not the box has been opened. We accept returns for defective products only, which we exchange within 30 days of delivery. This is a security limitation of these devices: once a device has left us, we cannot assure the next customer that it has not been interfered with.
How to arrange an exchange for a faulty item
- Message us on LINE at @siambc or email order@siambc.com before sending anything back.
- Include your order number, what is wrong, and a photo or short video.
- Send the item back to us at your own shipping cost. Once we have checked it, we exchange it.
Refunds: faulty items are exchanged rather than refunded.

How to check it is genuine
- The tamper seals on the box must be intactIf the seal is torn or the box looks opened, do not use the card and contact us right away.
- The card must show no signs of tamperingCheck both sides and the edges. There should be no pry marks, stickers, or numbers or writing on it. If you find any, do not use it and contact us right away.
- Set the card PIN yourselfSet the 6-digit PIN yourself when backing up in the OneKey app or on a OneKey Pro. Never use a card that already has a PIN or a backup on it.
- Back up only from your own app or deviceBack up by tapping the card to the OneKey app or a OneKey Pro. Never type your Seed Phrase into any website or send it to anyone.
- Keep a handwritten copy tooUse the Lite as a second backup and keep a handwritten Seed Phrase somewhere else.
OneKey Lite FAQ
How much is the OneKey Lite?
990 ฿ at SIAMBC, an official OneKey reseller in Thailand.
Does it work with the OneKey Classic 1S?
No. The Classic 1S has no NFC. The Lite works only with the OneKey app on an NFC phone and with the OneKey Pro.
What if I forget the card PIN?
The PIN cannot be recovered, and after 10 wrong attempts in a row the card wipes its data, so always keep a handwritten copy of your Seed Phrase too.
Does it need charging?
No. There is no battery; it runs on NFC power only while you tap.
Is it still made?
OneKey has stopped making the Lite and replaced it with the SeedCard. Lite cards still work for backup and restore as normal.
Is it water resistant?
Water and tear resistant, with no metal parts so it will not rust, but no IP rating is stated.
Will SIAMBC or OneKey ever ask for my Seed Phrase?
Neither will ever ask, for any reason. Anyone who asks for your Seed Phrase or PIN is a scammer, whether they claim to be SIAMBC staff, use OneKey's name, or say it is for a warranty claim, identity check or firmware update.
If you have any questions, you are always welcome to contact us. We'll get back to you as soon as possible, within 24 hours on weekdays.

Common questions
Which model should I choose? It depends on your phone. The Ledger Nano S Plus does not work with iPhone, and most Trezor models are view-only on iOS. Compare every model side by side.

Will anyone ask for my recovery phrase? Never. Anyone who does is a scammer.

Before you buy
Are your products genuine?
Yes. Every device we sell is new, sealed, genuine stock from authorized channels. SIAMBC has been Thailand's hardware wallet specialist since 2016 and has a physical store in Bangkok you can walk into.
This matters more than it sounds. A hardware wallet bought from an unknown marketplace seller can arrive already set up by someone else, with a recovery phrase they know. It is the one purchase where the seller genuinely matters.
How long does delivery take?
Orders normally arrive within 1 to 2 business days, depending on where you are — faster if you are in Bangkok.
Need it today? We can send it by Grab or LINEMAN for same-day delivery. Call us or message us on LINE to arrange it, pay by bank transfer, and it goes out immediately.
You are also welcome to collect from our Bangkok store.
Can I collect from your store instead?
Yes. We are in Thawi Watthana, Bangkok, open Monday to Saturday, 9:00 AM to 5:00 PM. You are welcome to come in, see the devices in person and ask questions before you buy. We answer in Thai and English. Find us here.
What warranty do I get?
Hardware wallets carry a 1-year warranty, claimed directly through us, with no waiting in an overseas support queue.
If a device is faulty out of the box, we replace it with a new one straight away. No forms, no waiting on the manufacturer.
The exception is the CryptoSafe range of steel recovery phrase backups: these products carry no warranty and cannot be returned or exchanged, as stated on their product pages.
How can I pay?
Credit card, bank transfer, or cash on delivery. You can also pay in person at our Bangkok store.
Can I set it up myself?
Yes, and you should do every step yourself. It takes a few minutes: you press every button on the device, create the wallet and write down your recovery phrase on your own.
Our step-by-step guides walk you through each step. If you get stuck, our team can answer on LINE or by phone, without ever seeing or asking for your recovery phrase.
Which model should I choose?
It depends on the phone you use and what you are protecting. The most common mistake is buying a wallet that does not work with your phone — the Ledger Nano S Plus does not support iPhone at all, and most Trezor models are view-only on iOS.
Compare every model side by side, or ask us. We will tell you honestly which one fits.
What happens if I lose my hardware wallet?
Nothing, as long as you still have your recovery phrase. The device only holds the keys — buy any compatible wallet, enter your phrase, and your crypto is back.
The real risk is losing the phrase itself. That is why we suggest keeping it on steel rather than the paper card in the box. Paper burns, water ruins it, and in Thailand termites eat it.
Will anyone ever ask for my recovery phrase?
No. Anyone who asks for it is a scammer, without exception. Neither SIAMBC nor any manufacturer will ever ask for your recovery phrase — not for a warranty claim, not for identity verification, not for a firmware update. Whoever has those words owns your crypto, and it can never be recovered.
