OneKey Classic 1S Pure BTC-Only
Which OneKey should you buy, and what does it cost?
Short answer: the Classic 1S Pure at 2,990 baht is the best place to start. For a touchscreen, fingerprint reader and air-gapped signing, go for the OneKey Pro at 8,590 baht.
The 1S Pure is card-thin with no battery to degrade: it connects over USB-C and Bluetooth, drawing power over USB-C while plugged in. The Bitcoin-only edition, also 2,990 baht, is the same hardware shipped with Bitcoin-only firmware. The Classic 1S, 3,450 baht, adds a built-in battery for cable-free use with a phone. The OneKey Pro, 8,590 baht, is the flagship: four secure elements, a 3.5-inch touchscreen, a fingerprint reader and air-gapped QR signing. The OneKey Lite card, 990 baht, backs up a recovery phrase over NFC and works with the OneKey Pro and the OneKey app only.
On chips: every model uses CC EAL6+ certified secure chips; the OneKey Pro carries four of them.
On phones: every model works with both iPhone and Android.

Why buy OneKey from SIAMBC
Short answer: with this kind of product, the supply chain is the point. The box should arrive factory sealed and you should be the first person to power the device on.
SIAMBC is an authorized OneKey reseller in Thailand with a physical store in Bangkok. Shipping is free nationwide, with same-day delivery in Bangkok. Before you start, it is worth reading how to spot a tampered hardware wallet.
Questions are welcome at the store or on LINE @siambc, in Thai and English. Setup stays entirely in your hands: you press every button yourself, and the recovery phrase is yours alone. Nobody at SIAMBC will ever ask to see it.
Common questions about OneKey
What is OneKey
OneKey is an open-source hardware wallet brand: the firmware is published for anyone to inspect. Your private keys live in a CC EAL6+ certified chip and every transaction must be confirmed on the device itself.
How much does OneKey cost
Devices start at 2,990 baht for the Classic 1S Pure. The Classic 1S is 3,450 baht, the OneKey Pro 8,590 baht, and the OneKey Lite backup card 990 baht. Genuine stock through the reseller channel, free delivery across Thailand.
Classic 1S vs 1S Pure: what is the difference
The battery. Both connect over USB-C and Bluetooth. The Classic 1S has a battery built in; the 1S Pure removes it entirely and draws power over USB-C only while plugged in, so there is no battery to degrade over the years. A good fit if you only plug in occasionally.
What does the OneKey Pro add
A 3.5-inch color touchscreen, a fingerprint reader, four secure elements, air-gapped QR signing, and support for the OneKey Lite backup card.
Does OneKey work with iPhone and Android
Yes, every model, through the OneKey app on your phone or the desktop app on your computer.
If I lose my OneKey or it breaks, are my coins gone
No. Restore them on a new device with the recovery phrase you wrote down during setup. The one rule: never show that phrase to anyone. Neither SIAMBC nor OneKey will ever ask for it.
Where can I buy a genuine OneKey in Thailand
From SIAMBC, an authorized OneKey reseller with a physical store in Bangkok. Every unit arrives factory sealed with a 1-year warranty. Avoid second-hand devices, which may have been set up before. See how to spot a tampered hardware wallet.
