We use Stripe as our external payment provider for online transactions at www.goldenspharmacy.ie. We require the billing address of the credit card you use so that we can pass this to Stripe, who check the address against the cardholder's details for security purposes. We only store delivery details when you opt-in to save these details to your Address Book. We don't store the credit card details on our server. Stripe requires that you provide your credit card details to process the transaction. This is done on a secure Stripe server and data passing between goldenspharmacy.ie servers and Stripe are encrypted.
