此项专利在9月17日获准，专利内容包括使用如“Bitcoin, Litecoin, Ripple, Peercoin, 和 Dogecoin”等数字货币在账户间进行资金转移。这种方法不仅可以加速转账过程，使整个过程更加可靠，同时还可以减少发送到如SWIFT等第三方清算机构的用户数据。此前跨境支付大部分是由SWIFT来完成的。
Banks are exploring a variety of uses for bitcoin and digital currency, but one area in particular appears to be piquing their interest: transferring funds between countries.
The latest evidence of that interest comes from Bank of America, which recently filed a patent for technology that would allow it to use the cryptocurrency for that purpose.
It makes sense that banks would focus on global money transfers. Sending money between countries is time consuming, costly, and involves third parties that aren’t really necessary.
The patent, granted on Sept. 17 and first reported by CoinDesk, describes using digital currencies like “Bitcoin, Litecoin, Ripple, Peercoin, and Dogecoin” to transfer funds between accounts. Doing so would help speed up the transfer, make it more reliable, and reduce the amount of customer data sent to third-party clearinghouses like SWIFT, which traditionally facilitate cross-border payments.
According to the patent, much of the action will take place on the backend of the transaction. After a customer submits for a money transfer, the bank would determine whether using a cryptocurrency would be appropriate, based on how quickly a traditional wire transfer can be processed and how expensive it would be. Also, Bank of America will be agnostic about the particular currency used—a cryptocurrency will be selected for a transfer based on a number of risk factors, including volatility and price. It will also try to make the settlement process “essentially simultaneously” to limit any changes in price.
Whether Bank of America will use ever use this patent remains to be seen; many financial institutions including MasterCard, Amazon, and JPMorgan have applied for bitcoin-related patents. Yet, despite the patents, none of them have actually started using bitcoin, most likely due to the uncertain regulatory climate surrounding digital currency.
