Improve credit card icon

[donatasben]

Hi.
It seems that current credit card icons are inconsistent between categories "Business Finance" (sharp corners, not very recognizable as a credit card) and "Internet security" (rounded corners, better).
Could you maybe improve the sharp cornered credit card icon or add a new one with rounded corners to be able to choose for consistency. In my opinion rounded cornered one looks more common and is easier to recognize.
Thanks!
