拍卖系统和asp.net与vb [英] Auction System and asp.net with vb

问题描述

我很好奇是否有办法在我的网站上处理/连接买家和卖家，而网站不必向买家收费并向卖家收取费用。换句话说，我不想触摸这笔钱，但我确实想在我的网站上尽可能地整合这个过程。



我想我是什么问的是拍卖网站如何管理买卖双方之间的交易？我真的不希望我的网站使用卖家的联系信息向买家发送电子邮件并说....这是卖家的信息。祝你好运。



Ebay似乎允许买家去PayPal并向卖家付款，但通过付款确认返回给Ebay。即使交易发生在买方和卖方之间，Ebay也能够检索有关该交易的一些细节。这仅仅是因为Ebay拥有PayPal，还是其他网站也可以这样做？

I'm curious if there is a way to process/connect buyers and sellers on my site without the site having to charge the buyer and credit the seller. In other words, I don't want to touch the money, but I do want to integrate the process as much as possible on my site.

I guess what I'm asking is how do auction sites manage the transactions between buyer and seller? I really don't want my site to resort to emailing the buyer with the seller's contact information and saying .... "here's the sellers info. Good luck with that."

Ebay seems to allow a buyer to go to PayPal and pay the seller, but returns back to Ebay with payment confirmation. Even though the transaction is between Buyer and Seller, Ebay is able to retrieve some details about that transaction. Is this simply because Ebay owns PayPal, or can other sites do the same?

推荐答案

就我所知，Ebay并不拥有PayPal。它的工作方式是大量的在线交易现在由专业的第三方支付服务处理，如 SagePay [ ^ ]，他们自己负责所有买家的信用卡详情比实际的网站。



当新客户第一次在网站（例如Ebay）上注册时，会创建一个唯一的令牌或订阅ID，使用该ID识别第三方支付服务的客户。当客户输入他们的信用卡详细信息时，这些详细信息不会存储在网站自己的服务器上 - 相反，它们只是传递给第三方，并在那里安全存储。然后，每当客户希望进行支付或购买产品时，网站就向第三方发送请求以从其账户中扣除XXX金额，向他们传递唯一令牌以识别客户。第三方执行交易并发回确认消息以通知交易是否成功，然后作为屏幕上的消息传递给客户。



PayPal略有不同，因为它们更像托管 [ ^ ]，或希望交换金钱的两方之间的中介，但这个概念本质上是同样 - 他们持有双方的信用卡详细信息，并在Ebay（或任何人）要求时自行执行交易。



这不仅是一种更安全的在线交易方式（考虑到目前所有的欺诈行为），但在英国等一些国家，大多数银行INSIST网站使用这种服务形式进行交易，以大大降低自己在线转账的风险。



我用来开发拍卖网站我自己，这就是我们所有交易的完成方式。希望有帮助

Ebay doesn't own PayPal as far as I know. The way it works is a great deal of on-line transactions are now handled by specialised third-party payment services such as SagePay[^], who take care of all the buyer's credit card details themselves, rather than the actual web site.

When a new customer registers on the web site (e.g. Ebay) for the first time, a unique 'token' or 'subscription' ID is created, which is used to identify the customer to the third party payment service. And when the customer enters their credit card details, these details are NOT stored on the web site's own servers - instead, they are simply passed onto the third party, where they are stored securely. Then whenever the customer wishes to make a payment or buy a product, a request is sent by the web site to the third party to debit their account for XXX amount, passing them the unique token to identify the customer. The third party performs the transaction and sends a confirmation message back to inform if the transaction was successful or not, which is then passed back as a message on screen to the customer.

PayPal is slightly different, as they work more like an escrow[^], or an intermediary between two parties wishing to exchange money, but the concept is essentially the same - they hold the credit card details of the two parties and perform the transaction themselves when requested to do so by Ebay (or whoever).

This is not just a much more secure way of doing on-line transactions (given all the fraud going on these days), but in some countries like the UK, most banks INSIST that web sites use this form of service to do their transactions to greatly reduce their own risk of transferring money on-line.

I used to develop auction sites myself, and this is how all our transactions were done. Hope that helps
