Cryptocurrency exchanges will buy and sell bitcoin on your behalf. As with wallets, it is advisable to do some research before choosing — you may be lucky enough to have several reputable exchanges to choose from, or your access may be limited to one or two, depending on your geographical area.

Other high-volume exchanges are Coinbase , Bitstamp and Poloniex , but for small amounts, most reputable exchanges should work well. With the clampdown on know-your-client KYC and anti-money-laundering AML regulation, many exchanges now require verified identification for account setup. This will usually include a photo of your official ID, and sometimes also a proof of address.

Most exchanges accept payment via bank transfer or credit card, and some are willing to work with Paypal transfers. Each exchange has a different procedure for both setup and transaction, and should give you sufficient detail to be able to execute the purchase. If not, consider changing the service provider.

Once the exchange has received payment, it will purchase the corresponding amount of bitcoin on your behalf, and deposit them in an automatically generated wallet on the exchange. This can take minutes, or sometimes hours due to network bottlenecks. If you wish recommended , you can then move the funds to your off-exchange wallet.

Bitcoin What is Bitcoin? How Can I Buy Bitcoin? From what I learned, funds could be reversed up to 60 days after the bitcoin purchase, if the funds used to do the purchase was stolen. Any ideas how the fraud risk could be reduced to a manageable level? For anyone interested I have a fully working implementation with Impulsepay.

A competent dev could probably whip out an implementation in a short time anyway. The thing is that if the customer would have to wait to be verified, the convenience is gone with the mobile purchase. Herodes on July 19, , CoinCidental on July 19, , Stephen Gornick on July 19, , Donator Hero Member Offline Activity: I used to run the service sms2btc.

It was however discontinued due to too high possibility of fraud. Search the forum for sms2btc. For example, you make a system where you have say 50 BTC in a hot wallet, and you create a system on your machines where you instantly deliver a private key to the target machine, thus making the btc instantly acessible by that machine user.

The problems with SMS paying for btc are many: If the user of the phone uses a stolen phone, or loaded credits with a stolen credit card, then the operators will reverse the charges, and the bitcoin supplier will be out of bitcoins, and not receiving any fiat.

The middle-men takes their fair share of cuts. This adds considerable surcharge to the coins, which means it is at no way competitive in comparison to using an exchange or a p2p trade. The fees are often exhorbiant, and the operator of the sms to btc system will often need to add a security buffer to avoid fraud. Payments can be reversed months into the future. What I can think of are persons who just need a little amount, to dabble into some gaming or just want to get a taste for BTC.

So, if for instance one plays in an internet cafe, and just wants to have some fun, I think most players wouldn't care much if they used 10 punds instead of 5 punds for their gaming pleasure. However, if it's a habbit of their, they will really waste a lot of money paying with SMS in the long run. And I assume you would like to make some money off offering this service?

Now - I don't know how many customers you have at your internet cafe, but one way I would think it would be possible to run a SMS to BTC gateway would be to work as hard as possible for the sake of reducing fraud. A plus is that any visitor would have to show themselves in the flesh, meaning that if you have security cams, you can track down rogue individual and report them to the proper authorities.

Also, anyone wishing to use this feature, should go to the front desk and present ID. Then front clerk should then check the ID against how the person looks.

Then the phone number of the user could be entered into the admin interface, and giving the user a certain amount of possible purchases for that day. The phone the user uses could be stolen, and the ID could be fake, but as we're not talking about large amounts of money here, not too many people would risk showing up in person and scam for such petty amounts. Every cafe users should be registered in the admin interface with their full name and their phone number, and they should not be allowed to add more than 2 phone numbers at most.

Also there could be limits as to how much they would be able to spend pr. If there's real demand to justify implementing such a system for your cafe, and by that I mean at least customers pr. The service would however only be available to customers on location, and the rules would have to be laid out clearly to avoid cheating. For instance it would be possible only to have the service work in your internet cafe, so they couldn't buy BTC with SMS once they got home.

Having to show ID and their person in meatspace, and having certain restrictions on spenditure yet allowing most people to have the fun they want would make for a more secure service with less fraud. But this also means that the clerks in the Internet Cafe would need to be vigilant. If they start just entering in and allowing phone numbers without verifying ID, scammers will eventually come in, get BTC with phone credits loaded from stolen CC's or stolen phones and cause a loss for your service.

I don't know if you also would be able to verify against the phonebook that the cell phone owners actually have their phones registered to the same name as their ID show.

Rules must be strict, and exercised equally for everyone. Clerks must be stern enough to withstand any pressure from visitors and gamers that wants to have their limits lifted prematurely. Another option would be to sell BTC for cash or debitcard directly at the front desk. If someone points to the fact that they want more BTC for their SMS'es, you can point to that there is a possibility for getting it with cash, but sadly they've currently exceeded their limit in regards to purchase over SMS.

The Internet Cafe could also decide what risk profile they would want to put on each user. This system could be altered to accomodate the needs of your operations. However, there would be needed to make a specification to what additions would be needed in the system for your special needs.

The way the current software works that I have programmed is this: User visits the website and enters which package he wants typically punds , user then gets a page with instructions and has to enter his phone number, or text a certain message to a service number, and then just following the instructions. Usually it means the user will receive a code on his phone, and he then has to enter this on the webpage. Depending on what services your users intend to spend the bitcoins on, it would be possible to speed up the delivery process.

For instance, if you're running nodes on your client machines, it would be possible to distribute a private key holding the funds to these machines, and thus making the BTC spendable immediately. Most of the time, the purchaser needs to wait confirmations before the coins can be spent, and that can take anything from 15 to 60 mins or more. Another way to do it would simply be to program a web-interface working on the intranet of the internet cafe, and after doing the payment procedure, the user will simply get access to spend a certain amount from your main bitcoin-node.

Let's say you have an IT-operator running the main bitcoin-node, and after a user have purchased bitcoins for say 10 punds, the successful purchase message is relayed to the main bitcoin-node and a certain webpage is made available to the purchaser from where he will be able to spend the bitcoins immediately.
