(35) "Security interest" means an interest in personal property or fixtures which secures payment or performance of an obligation. The term also includes any interest of a consignor and a buyer of accounts, chattel paper, a payment intangible, or a promissory note in a transaction that is subject to Article 9 of this title. The term does not include the special property interest of a buyer of goods on identification of those goods to a contract for sale under Code Section
11-2-401, but a buyer may also acquire a "security interest" by complying with Article 9 of this title. Except as otherwise provided in Code Section
11-2-505, the right of a seller or lessor of goods under Article 2 or 2A of this title to retain or acquire possession of the goods is not a "security interest," but a seller or lessor may also acquire a "security interest" by complying with Article 9 of this title. The retention or reservation of title by a seller of goods notwithstanding shipment or delivery to the buyer under Code Section
11-2-401 is limited in effect to a reservation of a "security interest."
Whether a transaction in the form of a lease creates a "security interest" shall be determined pursuant to Code Section 11-1-203.
