Bitcoin ATM Usage Question

[Omar2420]

This question is about using BitCoin ATMs to buy bitcoins. I'm fortunate enough to live close to several BitCoin ATMs.

I created a wallet using MultiBit HD. This is my first BTC wallet.

I see the way to generate the QR code is to click on Request and then put in the number of BTC requested. This generates a QR code that can be used with the ATM.

1. I am confused about this because, how can you know in advance the number of BTC that will be equivalent to like $20 or $50? How do you know the amount of BTC to enter into the request that will be equivalent to the cash I plan to put into the machine?

2. Do I have to leave the MultiBit HD application open on my PC before I use the ATM?

3. I believe I can just save the QR code in a PNG file and display it on my phone, or print it on paper and insert it into the ATM's scanner. Does this sound right?

Thanks everyone for your input.

1. Why don't you try to put $20 or $50 directly from usd text box it will automatically generate how much equivalent for bitcoins
And you don't need to relay in online price because atm is always updated about the price of bitcoin...

2. As far as i know you don't need to leave open your multibit hd application. anytime you can use atm with your smart phone make sure you have wallet applications like coinbase to store your bitcoins and withdraw it in atm..

3 You dont need to create PNG or any image save to your phone because you can generate qr code with coinbase application installed in your smart phone..

1) The ATM will be hooked up to the internet and will be getting the latest prices from an exchange or a number of exchanges and averaging them out.
2) Doesn't matter, it will sync up.
3) The QR Code can be either just an address linked to the wallet or an address and an amount linked to your wallet. So yeah saving it is fine.

Unless you leave it like a month, the price differences are not going to be too different if you saved a QR code for $20, it may be 0.048 when you leave and 0.051 when you get to the machine.
Remember, the machine will charge you a fee also.

Thanks. Is there some way in MultiBit HD to create a QR code linked to the wallet, rather a QR code linking to a wallet and an amount?
