CC Security code question

[elissawang]

In the sandbox，I am using AIM SDK to test simple transaction.Input the card number is 4111111111111111,
expiration date is 1120, and then after the security code is random input can still be traded。
I want to ask if in the formal environment, user input trading card number and expiry date,
Security code is input can be casually
The deal?Are there any restrictions on this？

the bank would declined the transaction if they are not correct.

Hello, please ask。In the sandbox，I am using AIM SDK to test simple transaction.I just input security code could be traded。Wait until the formal environment, if I enter the security code is not correct, the bank will check here is?

The sandbox is only simulating what the production would do. It does NOT send it to the processor to be process(check)
