【2019.12 更新】 Plastiq 已重新支援使用 Capital One 商業信用卡付款，個人信用卡暫時仍未獲 Capital One 解禁。H/T: Doc
【補充更新】 Doc 收到 Plastiq 電郵，說明 Capital One 信用卡付款被銀行單方面暫停。不知道是否群發，我兩個賬戶都沒有收到電郵。
As you know, Capital One has asked us to temporarily suspend processing of payments with their cards. We’re working closely with them to remedy the situation and will reach out as soon as we have an update for you. Meanwhile, consider trying some of these great credit cards that many of our customers use to pay their personal and business bills (list of Plastiq affiliate links of other card issuers)
根據讀者 batman 的提示，近期 Plastiq 似乎暫時無法使用 Capital One 信用卡付款，讀者 batman 是支付租金。Flyertalk 上也有類似 DP，應該已持續了一段時間，目前仍不清楚何時恢復正常。
