Payment systems can be adjusted by the product.
According to the product is very nice though payment option? For example, a product only make one payment to the credit card. or just provide payment by wire transfer of money. I think it would be a very useful product is the freedom to choose payment options.
For example, some products I want to make a campaign. Just pay with a credit card payment option is to facilitate single shot earner. Or just make money providing more than a cash payment.
Some products have the option to pay only that, other products such as payment option can be selected. I think we have a very useful option to pay for everyone.
