credit-card

问题 I'm aware that we can integrate in-app purchases with storekit. but i want to integrate payments using credit card. will apple allow to integrate such libraries? Are there any such libraries available where users can use their credit card for payment of products with in my app? 回答1: Depending on what users are purchasing*, you should be just fine accepting payments in your app. Instead of trying to incorporate some type of payment library into the app I would recommend using a payment API

问题 Our web app needs to be made PCI compliant, i.e. it must not store any credit card numbers. The app is a frontend to a mainframe system which handles the CC numbers internally and - as we have just found out - occasionally still spits out a full CC number on one of its response screens. By default, the whole content of these responses are logged at debug level, and also the content parsed from these can be logged in lots of different places. So I can't hunt down the source of such data leaks.

Problem3 - Any advice to improve on this coding (without

问题 Hi I am getting Invalid cardNumber error when transaction is done using card reader or scanning. The 'AnetApi/xml/v1/schema/AnetApiSchema.xsd:cardNumber' element is invalid - The value '"CARD_NUMBER"' is invalid according to its datatype 'String' - The actual length is greater than the MaxLength value. But it works fine when the CC number is entered manually. Could anyone please tell me what is the exact reason for this and how will i solve it? 来源： https://stackoverflow.com/questions/21191577

问题 I would like to limit the possibility of creating more than one account in a web application by a single person. How to do this? If you know how, you can directly answer this question.

The problem can be solved by assigning a unique persistent ID to each person registering in the application. If the person wants to set up another account, it won't be possible because he/she will

问题 I'm integrating with Authorize.net's ARB API. Authorize.net processes their transactions at a certain time everyday, so when people create a subscription, their transaction is not real time. I am creating a subscription based model, does their API tell me whether their CC has been processed? Or should I put a delay on the access to my site until they have processed all the ARB transactions that day. Thanks in advance! 回答1: You should be charging their first subscription payment via the AIM

问题 I was wondering what the best approach is to store encrypted credit card numbers in a SQL database for C# (.net framework). Should I do it manually by using String/SecureString/Byte Array with some sort of symmetric encryption ? I heard that for an alternative (and probably the easier option), a service provider (which you place the transaction with) will give you a key that can be used to retrieve transaction information. I don't know how to go about this approach, but is this the better

问题 It seems to me Apple won't allow this, but I need to make sure. For an app we're building, we want to ask the user to enter payment information (including credit card details) to pay for tickets. The transaction will be completed by calling a webservice of our service provider. The application we're developing will be a front-end for the services of our service provider. Please Note: We wouldn't be using Apple's in-app purchasing (IAP) system for this transaction. I'm concerned about the
