Huawei Health Card is the official size and appearance, and there is no small version. Or you can see if there are any settings in your Huawei Health. If there is, it can be adjusted. But there is basically no X.
The small version will also have some shortcomings, because with the small version, everything will be crowded together. I can't see it at all, and it's small and beautiful, which greatly affects the user's experience. What's worse, it will make users stop using this thing. On the other hand, the small version is not suitable for the size of the card. If there is a small version, it will look strange.
