Authorize.Net is a payment gateway that lets merchants accept payments online, by phone and in person. It supports credit and debit cards, eChecks and digital wallets such as Apple Pay, Google Pay and PayPal, and offers a virtual terminal, mobile payments, simple checkout buttons, digital invoicing, recurring billing, an Account Updater and fraud filters. According to its own site the service has existed since 1996 and is delivered as SaaS, including through resellers.
According to its website, Authorize.Net is a wholly owned subsidiary of Visa; Visa is a US company, so US law, including the CLOUD Act, applies. In its data processing agreement, Authorize.net acts as processor for its processor services and as controller for other permitted uses. The agreement relies on EU standard contractual clauses under Irish law and states that certain personal information is stored in the United States, including that of individuals in the EEA. Sub-processors are listed in the Merchant Interface. A European merchant should therefore plan for transfers to the US and may consider a gateway within the EU.
