Limiting the card width to be a bit smaller than it currently is would probably get the solution a bit closer to the design, or you could use a fixed aspect ratio to get a similar effect.
I really like that you used a css reset before styling the rest of the qr-code card.
Maybe you can try to extract variables for the colors and use them instead to make the code a bit more maintainable and readable for the future, but that is more of a personal preference of mine than a rule everyone should follow... Also to make the border-radiuses (is that the plural...?) a bit smoother between the outer card and the qr-code, you can look up the formula that is generally used to calculate the inner radius so it always follows the outer radius perfectly.
Pretty nice overall :)
