NFC的流动货币交易如何运作?
原标题:How does NFC mobile money transactions work?

I know how NFC works, but how does it store money and transfer money? Is it connected to the user s bank account? If so how does that mechanism work in terms of the infrastructure? A detailed explanation would be appreciated.

NFC payment works just as any normal contactless card payment.

每个卡片(即使是“虚拟”卡片,在向东北大西洋渔业委员会付款时,你使用的是“虚拟”卡片)都必须有账户。 它可以是你的借记,也可以是使用预付卡的匿名账户。 其中没有“钱”。 这笔钱属于账户。

当你用这些卡付款时,它以某种方式认证自己——它可能要求贵方银行申请认证,它可能这样做。 您可被请到您的PIN。 然后以某种方式核准交易。 如果所有物品都属于罚款,你就会得到你们购买的东西。

更不用说,为贵商提供服务的购买者(所付者)向贵银行发送有关交易的信息(通过签证、总账单或其他类似组织)。 然后,银行从你的账户中给他们钱。 当然,你的银行、签证/卡姆卡/......和购买者花钱来支付其费用,因此,商人实际上得到的钱比你少。 它称为交换费。

总体情况是这样,而大多数东北大西洋渔业委员会的付款选择采用一种或另一种方式,在认证“虚拟”卡和批准付款的确切方式上有所不同。 这使得东北大西洋渔业委员会能够利用现有的无联系付款基础设施。

如果贵方对无联系付款的细节或一般的心脏卡付款感兴趣,则考虑EMV标准。 如果不搞错,大约35%的支付卡和大约65%的点子使用这一标准。 http://www.emvco.com/“http://www.emvco.com/。 http://www.emvco.com/best_practices.aspx?id=217”http://www.emvco.com/best_practices.aspx?id=217。
