Compare Hardware Wallets
Each hardware wallet model may look similar, but the details can be quite different — from security chips and screens to connectivity and supported assets. Select 2–3 models below to compare, then turn on "Highlight differences" to see only what sets them apart, making it easier to decide.
Before choosing, the first thing to check is whether the model supports iPhone or Android. Some models support only one operating system, so checking compatibility with the device you use is an important step that shouldn’t be overlooked.

Which hardware wallet should you buy? Choose by budget and phone
If you would rather not work through the specs model by model, these are the wallets SIAMBC recommends, grouped by budget and by the device you already use. Every one is genuine and in stock, with full details on its own product page.
Under ฿3,000: Tangem Wallet 2-card set
The easiest to use: tap the card on your phone and you are in.
Each card carries a secure chip certified to CC EAL6+ and connects to your phone over NFC, on iPhone and Android alike. There is no battery to charge and no cable. The card has no screen of its own: transaction details show in the Tangem app, and you confirm by tapping the card.
The set comes with two cards, one to use and one to keep as a backup somewhere else. You can also set it up without a seed phrase, because each card works as a key on its own.
Best for: beginners who mainly use a phone. This model does not work with a computer.
At a similar budget: Ledger Nano S Plus has a screen on the device and a CC EAL6+ chip, and connects by USB-C to a computer or an Android phone. It does not work with iPhone.
Under ฿5,000: Trezor Safe 3
Both the firmware and the hardware are open to inspection.
Trezor publishes its firmware and the device's circuit design. Safe 3 is the most affordable Trezor with a secure chip, an OPTIGA Trust M certified to CC EAL6+. Your PIN and passphrase are entered on the device, never typed on the computer. It connects by USB-C to a computer or an Android phone, and also comes as a Bitcoin-only Edition.
Worth knowing before you buy: on iPhone it is view-only. You cannot set up the device or send from an iPhone.
Best for: computer or Android users who care about open source.
For iPhone users at this budget: Ledger Nano X has Bluetooth and works with iPhone (iOS 14 or later), plus USB-C for a computer. Its chip is certified to CC EAL5+.
Under ฿10,000: Ledger Nano Gen5
A large touchscreen that works with iPhone and computers.
The 2.8-inch E Ink touchscreen lets you read the destination address clearly before you confirm. The secure chip is certified to CC EAL6+. It connects by USB-C, Bluetooth and NFC, has a built-in battery, and works with iPhone, Android and computers. SIAMBC is an authorized Ledger reseller.
Best for: people who use both a phone and a computer and want a bigger screen than the earlier Nano models.
At a similar budget: Trezor Safe 5 has a 1.54-inch color touchscreen, open firmware and circuit design, and a CC EAL6+ chip. It connects by USB-C to a computer or Android, but is view-only on iPhone.
Best for iPhone users: Trezor Safe 7
The first Trezor that does everything on iPhone, from setup to sending.
It pairs with iPhone over Bluetooth and connects to a computer by USB-C. Inside are two secure chips, TROPIC01 and OPTIGA Trust M. It has a 2.5-inch color touchscreen and wireless charging, and like every Trezor, its firmware and circuit design are open.
Best for: people who mainly use an iPhone and want Trezor's most complete model.
On a smaller budget: Ledger Nano X works with iPhone over Bluetooth, or Tangem Wallet taps onto an iPhone over NFC.
For Bitcoin only: Blockstream Jade
Supports Bitcoin and Liquid, and nothing else.
The firmware is fully open source under the MIT license. It connects by USB-C or Bluetooth, or signs air-gapped through QR codes, and works with iPhone over Bluetooth in the Blockstream app.
Jade has no separate secure element chip. Instead it uses what Blockstream calls a Virtual Secure Element, which lets the whole device be open source.
Best for: people who hold only Bitcoin and want to sign without a cable.
If you want a certified chip: Trezor Safe 3 Bitcoin-only Edition (CC EAL6+, view-only on iPhone) or OneKey Classic 1S Pure BTC-Only (CC EAL6+, no battery, powered over USB-C).
Common questions
What is a hardware wallet
A hardware wallet is a device that keeps your private key inside it, rather than on your computer or your phone. Every transfer has to be confirmed by pressing a button on the device, and the key never leaves it.
That is what protects you. Even if your computer has malware on it, nobody can move your coins. Keep them in an app or on an exchange instead and the key sits on something that is connected to the internet all day.
Which hardware wallet is best
There is no best model for everyone, only the one that suits how you will use it. The table above compares every model.
Three things are worth settling before anything else. Does it work with an iPhone, because many models do not. Does it have a separate security chip, because some have none. And is the source code open for outsiders to check.
If you do not know where to start, answer two questions. Which phone do you use, and how often will you move coins? Those two rule out most of the list on their own.
How Trezor and Ledger differ
The first difference is open source. Trezor publishes its firmware and its hardware design for anyone to inspect. Ledger publishes only its apps and SDK, not the firmware on the device or the secure element.
The second is phones. Ledger has had Bluetooth models for years. On the Trezor side that only arrived with the Safe 7, which is the first Trezor that works with an iPhone. Every other Trezor connects to Android over USB-C perfectly well, but on an iPhone you can check balances and nothing more.
Both brands use certified secure elements, though the certification level differs from model to model. The table above has it model by model.
Which hardware wallets work with iPhone
A model that works with an iPhone has to connect wirelessly, so Bluetooth, NFC or QR code scanning, because iPhone does not allow a USB cable connection to a wallet the way Android does.
The table above shows which ones do. The brand buttons above it narrow the list to one brand at a time.
One thing worth knowing: some models let you open the app and check balances on an iPhone but cannot send. Those are not the same thing.
Where to buy a genuine hardware wallet in Thailand
SIAMBC has been an authorized distributor in Thailand since 2016. Every device is new, factory sealed, genuine stock from authorized channels.
This matters more than it sounds. A second-hand device, or one from a middleman you do not know, may already have been set up before it reached you, which means the recovery phrase belongs to the seller and not to you, and they can empty it whenever they choose.
We have a real shop in Bangkok where you can look at a device before deciding, free delivery nationwide, and same-day delivery within Bangkok.
