Hi, Second case will be right, when transaction1 will be in queue until transaction2 draw money from ATM. Because whenever first process will be working, second process will be waiting in queue. After first process get done then only second process will proceed in queue for execution. This thing will also happend in Transaction of two ATM cards.

Hi This is correct:- Transaction1 will be queue until Transaction2 draw money from ATM. Because of your first case "Create two instances for to do transaction" it will be deadlock. Ex:- Suppose you have 500 rupees. If you use First case, First card want draw 300 and second card want draw 300 rupees then in that case it does not work.

To do an online credit card transaction in ASP.NET using PayPal Payflow Pro, you'll need to set up a Payflow Pro online payment gateway account at PayPal.com, download and install .NET SKD for Payflow Pro, and create an ASP.NET application that sends a transaction request to and receives a transaction response from Payflow Pro. http://www.codeproject.com/KB/aspnet/PayPal_PayflowPro.aspx
