This is meant to be a subjective question on whether or not the PayPal Payment Button is considered a “hobby”-level feature in an otherwise professional e-commerce web application.
Personally, I tend to cringe a little when I go to buy something and see a PayPal button in place of an in-house shopping cart. On the other hand, I’m sure my data is a lot safer with PayPal than with a lot of self-hosted services.
Is this a legitimate UI reputability concern, or am I an e-commerce developer snob? Would you worry about this in your applications?
A lot of large Internet stores offer PayPal as an option. I pay my cell phone bill with PayPal. PayPal is well trusted and main stream. I don’t think it is a “hobby-level” option at all. I’m sure many users would appreciate the extra payment option.
Where you might possibly run into a reputability concern is if you only offer PayPal as an option. That might raise a red flag in a lot of users’ eyes because it has such a low barrier for entry; contrast that to a merchant account where you have to have a real business to take payments by credit card.
