How to integrate payment method

[dianacasoria]

I have a real estate website where I help people to buy & sell their property under one roof where we are covering different projects. I want to add the secure payment method for my clients which has full security so that my customers feel safe and secure while spending their money to choose our services
Suggest me some good and secure payment methods and how can I do this.
Loads of thanks!

I'm making a catering app and I need to have a way for the user to pay for their order. What's the best way of doing this? I'd like to avoid requiring the user to use a payment service like PayPal (I want them to be able to pay with their credit card information).
