Hello, security is a core component of all payment gateways, so every transaction between the merchant and the issuing bank is encrypted to protect sensitive financial information. For example, PayAdmit is a software for cashier (https://payadmit.com/features/cashier-services/) that allows small and medium-sized online merchants to accept credit card and electronic check payments from websites and automatically deposit funds into their bank account. This will make online payment processing easier and safer.
