The Aviary (Store) uses Stripe Checkout – this allows VIHMIRU to process direct credit or debit card payments, boast a reduced checkout time (meaning it's much faster and simpler), plus you stay on VIHMIRU; there is no redirect off to third-party payment websites.
Very! Stripe Checkout forces HTTPS for all its services as well as putting high level encryption on all card numbers that go through the system.
Sorry, no. PayPal has been phased out and replaced with Stripe.
