(a) A state bank may engage in the banking business at its home office, at an approved branch office location, and through electronic terminals. A drive-in facility must be approved as a branch if it is more than 2,000 feet from the nearest wall of the bank’s home office or another approved branch office.
(b) A function of a state bank that does not involve banking contact with the public may be conducted at any location without prior written approval of the banking commissioner. The finance commission may adopt rules further defining functions of a state bank that are not required to be conducted at an approved location.

(c) The finance commission by rule under Section 32.009 may authorize a new form of banking facility. The banking commissioner may approve a new form of banking facility other than as provided by this subchapter if the banking commissioner does not have a significant supervisory or regulatory concern regarding the proposed facility.
