未来就在现在。 CoinCorner 的 Bolt Card 是一种无屏幕的非接触式借记卡，非常方便。该产品指向比特币进化的下一阶段，即由闪电网络提供支持的循环经济的创建。这张卡是弥合比特币与普通大众之间鸿沟的想法吗？
在比特币 2022 大会，Jack Mallers宣布 Strike 将把闪电支付带到美国一半的销售点终端。对开发感到兴奋，我们将其描述为：
“Strike 与 Blackhawk 和 NCR 合作，将比特币支付带到美国日常业务中的数十万个销售点终端。这包括大卖场、主要商店和每家快餐连锁店。”
然而，Mallers 展示的视频是一个演示。该产品尚未准备就绪，更不用说已经部署了。另一方面，Bolt Card 已经开始工作了。不过，某些条件适用，您将在下文中了解到。 CoinCorner 是完全迷失了方向还是有所了解？让我们看看解决问题的另一种方法。
CoinCorner 直接从马恩岛来找我们，将 Bolt 卡描述为“离线闪电非接触式卡”。借鉴已经提到的 Jack Mallers 的观点，他们将比特币网络描述为“一个全球性的、开放的、无需许可的、去中心化的货币网络”。

CoinCorner 首席执行官丹尼·斯科特 (Danny Scott) 撇开谦虚不谈，宣称：“这是真实世界的创新，其产品将在日常生活中为现实世界的人们提供帮助。”他说的是一张“附在您的 CoinCorner 账户上”的借记卡，用户可以用它消费英镑、欧元或沙特阿拉伯。
在上面的视频中，您可以看到正在运行的 Bolt Card，Scott 在这里解释了到底发生了什么：
“离线 NFC（非接触式）卡“点击”了支持 Lightning 的 POS 设备，它请求所需的付款，我的@币角帐户获取了我的英镑，将其转换为 BTC，并立即通过闪电网络将 BTC 发送给商家，并立即结算。”

根据 CoinCorner 的说法，借记卡的销售点是现场闪电支付尚不实用。该公司认为，这些交易“仍然没有我们为大众所需要的那样高效和用户友好。我们仍在打开手机，打开应用程序，扫描二维码，然后进行交易。”
这真的是个问题吗？基于手机的支付解决方案比比皆是，人们似乎对它们很满意。二维码模型比较常见，并不是比特币闪电支付独有的。另外，人们喜欢他们的手机。无论如何，显然，非接触式卡在英国是常态。所以，也许 CoinCorner 有所作为。

这种支付解决方案的局限性在于它需要支持 CoinCorner Lightning 的 POS 设备才能工作。该公司“目前在马恩岛的大约 20 家商店拥有设备，并将于今年在英国和更多国家/地区推出”，但仍然如此。无论如何，CoinCorner 承诺其目标是与整个闪电网络互操作，因此，“你很快就能在整个国家使用你的闪电卡。”
另一个限制可能更令人沮丧。缺少屏幕意味着用户无法在自己的设备上验证交易的详细信息。这意味着，他们必须相信商家不会多收他们的钱。这是一个大问题，考虑到比特币的非官方口号是“不信任，验证”。然而，没有任何解决方案是完美的，并且总是需要权衡取舍。
