wallet opens from lock screen requesting face id, like trying to make a payment

It has already happened to me twice when when I go to unlock my iPhone, instead of the lock screen appearing, the wallet app appears with my card there, asking me to put my face, just like when I go to pay for things with wallet, but this happened in my room for no reason and now I'm worried that someone is trying to use the wallet app to pay something and they just need me to look at the face id to complete the payment and rob me.
