I am a UX designer and I use your card ready often at my local coffee shop. Almost every time i use it, I mindlessly pull my card out too early. I paid attention to why I am doing this and it’s because you are using the same animation to insert the card as you do to remove the card. When this animation plays to insert the card, I have already inserted my card, so for a split second, I think it’s prompting me to remove it. I suggest you either only play this animation if someone has not yet inserted the card or play a different animation for each instance
