User manual:Making payments
In order to make payments, go to the account page in Trezor Wallet and press send. You should see a payment page like this:
1. Enter the destination address
You can type in a destination address for your transaction and the value of coins which are about to be sent. Now you can choose to insert the amount in bitcoins or any other world currency (actual exchange rate is provided by CoinDesk).
If the address you want to send to is on someone's cell phone, you might not want to type in the full address. Chances are, though, that they'll also be able to show you the QR code for their account. You can scan a QR code with Trezor Wallet simply by pressing the scan QR code button in the address field and holding a picture of the QR code up to your computer's webcam.
It's also simple to send the maximum possible amount from the current account. Just press the "arrow" button in the BTC field (see image below)
You can send bitcoins to multiple addresses with one transaction by pressing the '+' button in the right-hand corner of the Send page. You can also choose to add multiple transactions by clicking on the "Import from CSV" button.
This is both convenient and saves you money in transaction fees, which you can now also set manually. There is 4 different levels of priority (high, normal, economy, low) and the fee amount and estimated confirmation time is based on bitcoinfees.21.co service.
In case you have enabled Labeling you will also see "Comment" row, where you can write a comment for the current transaction. Please find more information about how the Labeling works in the link above.
2. Enter your PIN
The first time you make a payment with your Trezor after plugging your Trezor in, you must enter your PIN. This is because each time you plug in your Trezor, your Trezor starts in a locked state. Once you have entered your PIN for the first time, your Trezor will be unlocked until it is unplugged again. If you need help entering your PIN, please see entering your pin.
3. Confirm the transaction on your Trezor
Once you have pressed send and entered your PIN, you will be asked to confirm your transaction. Check the amount of the transaction and the destination address. If the amount and address are correct, press the right button on your Trezor to confirm. If they are wrong, press 'cancel'. If they are wrong, it may mean that your computer has been infected with a virus and you can be happy that your bitcoins are safe in your Trezor, and not already stolen.
Once you have confirmed the destination address(es) and amount(s) of your bitcoin transaction, your Trezor will display the total amount of the transaction along with the transaction fee. Again, check to make sure these are reasonable before pressing confirm.
You can watch the progress of your outgoing transactions by switching over to the Transactions window. Outgoing transactions are marked as red.
