Bitcoin wallet service Coinbase has created an SMS interface, which enables users to send and receive bitcoins via text message.

Any Coinbase customer, regardless of the network they are on and whether or not they have a smartphone, can use the new service. First, users have to head online and visit their Coinbase account page, verify their phone number, select a six-digit pin and click the ‘enable SMS’ button.

After sending ‘hi’ to 1 (650) 316-5555, the service is activated and the user can complete any of a number of actions, for example sending bitcoins to a friend’s Coinbase wallet, checking the current price of bitcoin and selling bitcoins.

Complete list of Coinbase SMS commands:

balance (b or bal) – you’ll receive your bitcoin balance via text message

– you’ll receive your bitcoin balance via text message transactions (t or txns) – you’ll receive a text message detailing your last three transactions

– you’ll receive a text message detailing your last three transactions address (a or addr) – you’ll receive a text message showing your bitcoin address for receiving bitcoins

– you’ll receive a text message showing your bitcoin address for receiving bitcoins qr (q) – you’ll receive a QR code image link for your bitcoin address (only available on certain handsets)

– you’ll receive a QR code image link for your bitcoin address (only available on certain handsets) request (r or req) – a request for bitcoins will be sent to the email address or phone number you choose

– a request for bitcoins will be sent to the email address or phone number you choose send (s) – you’ll send bitcoins to an email address, a bitcoin address, or a phone number of your choice

– you’ll send bitcoins to an email address, a bitcoin address, or a phone number of your choice price (p) – you’ll be sent the current Coinbase buy/sell price

– you’ll be sent the current Coinbase buy/sell price buy – buy bitcoins and debit your primary bank account

– buy bitcoins and debit your primary bank account sell – sell bitcoins and credit your primary bank account

For the actions that involve buying, selling and sending bitcoins, the user will receive an automated phone call and will be prompted to enter their pin.

“We decided to add an SMS interface because we feel that bitcoin should be accessible to anyone,” said Fred Ehrsam, co-founder of Coinbase. “There are many in the world that don’t have access to a smartphone, and there’s large overlap between that group and the underbanked. As a result, adding an SMS interface helps us begin to reach some of the people in the world that stand to gain from bitcoin the most.”

The SMS interface was built by Coinbase’s new recruit Charlie Lee, the creator of Litecoin. It is one of many developments the company has made since it received a $5 million investment led by Union Square Ventures in May.

Coinbase was involved in the 2012 summer programme of elite startup incubator Y Combinator, which has nurtured a number of successful companies, including reddit, Airbnb and Dropbox.

Y-Combinator’s co-founder Paul Graham labelled Coinbase’s rapid growth as “very, very rare.”

“Hackers are the animals that can detect a storm coming or an earthquake. They just know, even though they don’t know why, and there are two big things hackers are excited about now and can’t articulate why – Bitcoin and 3D printing,” he added.

Kipochi offers a similar product to those based in numerous regions across the world, including the Middle East, Africa and South America.

Kipochi, which means purse or wallet in Swahili, is like Coinbase’s new system in that users’ mobile phone numbers act as their account numbers, enabling them to buy, sell, send and receive bitcoins via their handsets. It works on all web-enabled mobile phones and operates with very low transaction fees.
