I am using a payment gateway in my app.
I'm thinking of storing credit card numbers without the CVC numbers in my app.
Storing the CC number eliminates the requirement of re-entering the CC number. However, the user must still enter the CVC number.
The CC number itself will be encrypted with AES and a user defined key.
- Is it secure to store credit card data in an App this way?
- How secure is this implementation in Android versus other OSes?
