Uber携手Bitcoin Builder 专车支付迎来比特币时代
Bitcoin Builder在Uber网络上建立了一个商业账户，这样Bitcoin Builder就可以作为一种支付方式显示在Uber移动端app上。
用户需要将Bitcoin Builder的多重签名电子钱包同该公司的Uber商业账户绑定。在激活之后，用户就可以在Uber移动端app的“选择支付方式”中看到Bitcoin Builder的支付选项了。
如果用户打算取消Bitcoin Builder服务，或者Uber计划删除商业账户，那么Bitcoin Builder将通过比特币把余额退还给用户。
一位Bitcoin Builder的代表表示： “你可以随时随地把账户中的所有余额提取出来，系统会通过比特币将余额支付给你。”这种退款机制类似Fold在星巴克提供比特币支付的方式。（译者注：Fold是一款app，让你在星巴克用比特币支付并获得20％折扣）
到目前为止，Uber账户上的所有余额都是用美元结算的。不过，按照Bitcoin Builder的说法，用户可以在打车之前既可使用比特币充值，因为在Bitcoin Builder上支付比特币不需要任何审核。如此，用户若不需要使用打车服务，就可以保留自己的比特币（以免交易后贬值等情况）。
US-based bitcoin exchange platform Bitcoin Builder has announced their release of a bitcoin service that enables users to pay with bitcoin for Uber rides.
How it Works
Bitcoin Builder created a business account on the Uber network, which allows the firm to display itself as a payment method on the Uber mobile app.
Payment by Bitcoin Builder
Users are required to use the Bitcoin Builder multi-sig wallet to associate it with the firm’s Uber business account. After the activation, users will see Bitcoin Builder as a payment option on the “SELECT PAYMENT” section of the Uber mobile application.
The service works everywhere Uber works, even in countries like India, where credit card penetration is below 2%. According to a report published by The Hindu Business Line, the number of credit cards stood at 21 million by 2014-15. Currently, Uber does not accept debit cards in the country. Uber India takes Paytm, a centralized payment network in India for its local users. But now, Bitcoin Builder’s bitcoin-to-Uber service will give many in India that do not own credit cards or bank accounts an option to pay for the service in another way.
“India needs this service terribly,” said an Uber user in India on Reddit. “Uber does not accept debit cards and many of us don't have credit cards…people use cash a lot in India. Bitcoins bought in India are primarily bought in cash. If service like this could be extended to other services, it would be awesome.”
If a user decides to stop using the service of Bitcoin Builder or if Uber decides to cancel the firm’s business account, Bitcoin Builder will refund the remaining balance instantly via bitcoin.
"You can always request all the money remaining in your account back at any time, and it'll be paid instantly via bitcoin,” a Bitcoin Builder representative announced. This refund method is similar to Fold’s approach with its discounted bitcoin payment option at Starbucks.
As of now, all balances are held in U.S. dollars. However, users are allowed to send the bitcoins right before the ride, as Bitcoin Builder accepts bitcoin with zero confirmation. The firm’s representative explained: “It's held in USD […] but you can always just send the BTC in right as you're about to ride, we accept it with zero confirmations, so that way you can keep it as BTC as long as you're not about to use it.”
