YoKey 7A USB-A 是一把实体安全密钥,用来取代短信验证码和验证器 App。登录时按一下密钥即可,账号被盗的难度会大幅提高。
为什么安全密钥比短信和 App 动态码更靠谱
一个做得像模像样的假登录页,能在你输入的那一刻同时拿到密码和一次性验证码,攻击者几秒之内就能用掉。安全密钥骗不了:它会先核对网站的真实域名再作出响应,所以假页面什么都拿不到。这就是为什么用上密钥之后,钓鱼这条路基本就走不通了。
主要特点
- 通过 FIDO U2F 与 FIDO2 认证
- 基于 NXP 恩智浦 芯片打造
- 主流浏览器直接可用,不需要安装任何东西
- 插入电脑或笔记本的 USB-A 接口
- 可防住钓鱼攻击和账号被接管
可以在哪些地方用
任何支持 FIDO 安全密钥的服务都可以,包括 Google、Facebook、Instagram、X、Microsoft、Apple、GitHub、Dropbox、币安和 Coinbase。多数账号支持注册不止一把密钥,我们建议再备一把作为备用。
为什么在 SIAMBC 买
SIAMBC 自 2016 年起就是泰国的硬件钱包与安全密钥专营商,曼谷设有实体店。保修和售后由我们自己的团队处理,泰语英语都可以。
买之前值得知道
重要账号请再注册一把备用密钥,或者把服务给你的恢复码保存好。如果某个账号只有这一把密钥能进,一旦丢失,找回会很慢。

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: the warranty period differs by brand and by model, 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.
Non-defective products: for security reasons we cannot accept returns or exchanges on non-defective items. A hardware wallet that has left our hands and come back cannot be resold as sealed. Please check compatibility before ordering — compare every model side by side or ask us first.
How to arrange a replacement
- Message us on LINE at @siambc or email order@siambc.com.
- Include your order number, what is wrong, and a photo or short video.
- We will arrange the replacement.
Refunds: we exchange faulty items rather than refund them.

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.
Are your products genuine? Yes — new, sealed and sourced through official distribution, from a physical shop in Bangkok you can walk into.
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 and sourced through official distribution. 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?
Products are covered by the manufacturer's warranty against manufacturing defects. The warranty period differs by brand and by model — ask us if you need the period for a specific device.
If a device arrives faulty, we replace it with a new one straight away. No forms, no waiting on the manufacturer. For a later claim, contact us with your order number and proof of purchase and we handle it with the manufacturer on your behalf, rather than sending you to an overseas support queue.
CryptoSafe steel backup products are the exception: they are sold without warranty and cannot be returned or exchanged, as stated on those product pages.
How can I pay?
Credit card, bank transfer, or cash on delivery. You can also pay in person at our Bangkok store.
Will you help me set it up?
Yes. Bring your device into the shop and we will set it up with you — creating the wallet, writing down the recovery phrase properly, and checking you can send and receive before you leave.
Setting up a hardware wallet is the step people most often rush, and it is the one that matters most. If you would rather do it at home, ask us anything on LINE.
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.
