Two Order Types ERD

Hi, im new to database design and im trying creating an ERD for a pharmacy that sells products online and also accepts repeat prescriptions orders to customers.

Here is my ERD:

I'm wondering how i could only make use of only 1 payment and card details entity for both orders. Would i be able to make a relationship between the ORDER TYPE entity and payment/card details entity.

Any help would be appreciated. thanks
