Bitcoin ATMs

Bitcoin ATMs are already being set up in many countries of the world: Vancouver (Canada), Boston, Austin (U.S.), Hong Kong, Helsinki, Zurich and Singapore. This is certainly not a complete list and it is constantly getting new entries.

Bitcoin ATM looks almost exactly like a regular ATM. Some ATMs can sell Bitcoins as well as buy them.

• Purchasing: in order to buy a certain number of Bitcoins through such ATM the correct sum of money has to be inserted in it and a printed QR-code is handed out in return. Just generated text and numeric address of your Bitcoins also appears on the screen.

• Selling: In order to sell Bitcoins, i.e. to get cash from the ATM, you have to enter the address from which Bitcoins will be taken or scan a QR-code with your phone (if the phone has Bitcoin wallet installed on it) and send your Bitcoins to said address. In return the ATM will give you cash.

Mechanisms of work of some ATMs are such that privacy can potentially still suffer: to proceed to operations the machine requires palm scanning. This function is introduced to prevent money laundering (so the same person would not be able to withdraw large sums within a certain period of time). Some Bitcoin ATM's manufacturers build scanners for state documents such as passports or drivers' licenses into their machines.Blockchain for Android

Smartphone apps

Various smartphone apps are created to conduct operations with Bitcoin.

Blockchain

Blockchain is not just a browser of all blocks and transactions in Bitcoin network, but also an online wallet meant for storing and exchanging Bitcoins, without the installation of a large Bitcoin-qt distribution on your computer.

This wallet app was created for iPhone. It allowed to transfer Bitcoins, utilize phone's camera for QR-codes scanning, receive Bitcoins and conduct exchange directly between smartphones.

But Apple's policy has not supported the idea of cryptocurrencies and the application was soon removed from the AppStore.
