预付卡激活的工作原理

发布于 2024-11-28 10:15:45 字数 502 浏览 2 评论 0原文

我正在寻找一些关于预付卡如何工作的良好技术概述。这篇帖子提供了一些基本答案,但我想了解更多信息。

我正在帮助开展一个项目,我们将发行预付卡,最终用户将使用这些卡来支付服务费用。我们不打算使用任何第三方处理器。我们将编写自己的软件。

谁能给我提供一些技术资源,以便我可以了解更多有关行业标准的信息?我的一些问题是:

  • 帐号的标准方案是什么?

  • 条形码:它们在卡激活中发挥作用吗?难道它只是在销售点查找商品的代码吗?

  • 卡激活:除了验证帐号是否存在于数据库中并且之前未经过验证等之外,还有什么其他作用吗?

  • 解锁 PIN:这与标记帐户已激活相同吗?

先感谢您!

I am looking for some good technical overview of how prepaid cards work. This post provides some basic answers but I would like to learn more.

I am helping with a project where we are going to be issuing prepaid cards that end users will use to pay for services. We don’t plan on using any third party processor. We will write our own software.

Can anyone point me to some technical resources so that I can learn more about industry standards? Some of my questions are:

  • What are standard scheme for the account number?

  • Barcode: Do they play any role in the card activation? Isn’t it just a code to look up the item at the Point of Sale?

  • Card activation: Is there more to it than validating that the account number exists in the database and has not been validated before etc.?

  • Unlock the PIN: Is this the same as flagging the account has been activated?

Thank you in advance!

  1. 帐号可以是任何内容。只是不要使用简单的递增数字,这样猜测帐号就很容易了。
  2. 条形码充当卡的一种 UPC,尽管它同时具有帐号和识别信息,表明“这是零售商 X 的卡,金额为 Y 美元”。PIN
  3. 码可防止某人简单地扫描该卡批量条形码并“窃取”金额。如果没有帐号和密码,该卡将无法激活。通常,密码印在卡上的刮擦条下,或者隐藏在包装下,以便在不对卡或包装造成明显“损坏”的情况下无法读取密码。
  1. The account number can be anything. Just don't use a simple incrementing number, such that it's trivial to guess account numbers.
  2. The barcode serves as a sort of UPC for the card, though it'll have both the account number, and identifying information saying "this is a card for retailer X, in the amount of $Y"
  3. The pin prevents someone from simply scanning the barcodes in bulk and "stealing" the amounts. Without the account number AND the pin, the card cannot be activated. Generally the pin is printed on the card under a scratch-off strip, or is otherwise hidden under packaging so that it can't be read without very obvious "damage" to the card or packaging.
