Compare Hardware Wallets
Hardware wallets look much alike. What separates them is the secure chip, the screen, how they connect, and which coins they hold. Pick two or three below, then turn on Highlight differences to strip out what they share and leave only what you have to decide.
Before anything else, check whether a model Works with iPhone or Works with Android. Many support only one, and that is the most common reason people buy the wrong device.

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 all 36.
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 and bought through official distribution.
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.
