Just like Stripe, the use of Paystack as a payment method does not require creating or having a Paystack account.
In fact, Paystack is a Stripe-funded company and the technology the service is using are all Stripe even though it is own and managed by Nigerians.
To use Paystack, all you have to do is to add your credit or debit card, step through the payment process and the system (both ours and Paystack's) will guide the process to completion.
Before proceeding, please do ensure that you have set your payment currency to the Nigerian Naira, and that you have your mobile device (phone) with you as authorization is required by the payee to complete the process.
We are working to make it possible for customers wishing to pay in $USD to use the service and will be rolling that out soon.
