1.__This section gives the issuer of a letter of credit or a nominated person thereunder an automatic perfected security interest in a "document" (as that term is defined in Section 5- 102(a)(6)).__The security interest arises only if the document is presented to the issuer or nominated person under the letter of credit and only to the extent of the value that is given.__This security interest is analogous to that awarded to a collecting bank under Section 4-210.__Subsection (b) contains special rules governing the security interest arising under this section.__In all other respects, a security interest arising under this section is subject to Article 9 [Maine cite Article 9-A].__See Section 9-109 [Maine cite section 9-1109].__Thus, for example, a security interest arising under this section may give rise to a security interest in proceeds under Section 9-315 [Maine cite section 9-1315].

2.__Subsection (b)(1) makes a security agreement unnecessary to the creation of a security interest under this section.__Under subsection (b)(2), a security interest arising under this section is perfected if the document is presented in a medium other than a written or tangible medium.__Documents that are written and that are not an otherwise-defined type of collateral under Article 9 (e.g., an invoice or inspection certificate) may be goods, in which an issuer or nominated person could perfect its security interest by possession.__Because the definition of document in Section 5-102(a)(6) includes records (e.g., electronic records) that may not be goods, subsection (b)(2) provides for automatic perfection (i.e., without filing or possession).

Under subsection (b)(3), if the document (i) is in a written or tangible medium, (ii) is not a certificated security, chattel paper, a document of title, an instrument, or a letter of credit, and (iii) is not in the debtor's possession, the security interest is perfected and has priority over a conflicting security interest.__If the document is a type of tangible collateral that subsection (b)(3) excludes from its perfection and priority rules, the issuer or nominated person must comply with the normal method of perfection (e.g., possession of an instrument) and is subject to the applicable Article 9 [Maine cite Article 9-A] priority rules.__Documents to which subsection (b)(3) applies may be important to an issuer or nominated person.__ For example, a confirmer who pays the beneficiary must be assured that its rights to all documents are not impaired.__It will find it necessary to present all of the required documents to the issuer in order to be reimbursed.__Moreover, when a nominated person sends documents to an issuer in connection with the nominated person's reimbursement, that activity is not a
