How To Buy Bitcoins At ATM Directly To Hardware Wallet

Send Bitcoins from an ATM Directly to a Hardware Wallet

Bitcoin ATMs make buying bitcoins easy and fast. Bitcoins purchased from Bitcoin ATMs are delivered to the recipient in one of several ways:

  • a private key printed on receipt paper;
  • encrypted with user given password a private key is sent by email;
  • to a Bitcoin address provided by user and scanned at the machine before payment.

What if, however, you want to deliver your bitcoins directly to a bitcoin hardware wallet? Hardware wallets don’t have screens and require software to interact with the device. So how can you send bitcoins from an ATM directly to your hardware wallet?

Mobile HD Watch-only Wallets

Using a mobile wallet like Mycelium or Sentinel, you can import your hardware wallet HD seed onto your mobile device. This allows you to view your hardware wallet addresses and accept payments to your hardware wallet from your phone. There will be no need to even carry or bring the hardware wallet with you to the ATM.

Finding your Hardware Wallet HD Seed

Your HD seed can be found using the software wallet currently paired with your hardware wallet.

TREZOR

To find your TREZOR HD public key, login to myTREZOR.com and click on your device name on the left side. In this case “TREZOR Device”.  Click “Show XPUBs”:

Using a Block Explorer

You’ll have to use a Bitcoin block explorer to send to your hardware wallet if you don’t have an Android phone.

First, open the software wallet you currently use with your hardware wallet. Get an address from your wallet and copy and paste it into a Bitcoin block explorer like Blockchain.info.

If you’ve successfully completed the search for this address, you should see a QR code at the top of the page:
Blockchain.info

Bookmark this page and access it on your mobile device. Now you can scan this QR code from your phone at a Bitcoin ATM and send directly to your hardware wallet.
