(a) It is illegal for any banking institution or other depository institution to conduct its business in a facility that is a mobile unit not permanently attached to the real estate upon which it is located, except: (i) That such mobile units may be used as temporary banking quarters pending construction of a permanent bank building on the same or adjacent property thereto if a charter for said bank has previously been approved; or except (ii) as provided by subsection (b) of this section. This section shall not be construed or interpreted to prohibit a financial institution from providing messenger services to its customers by which items are received by mail, armored car service or other courier or delivery service for subsequent deposit: Provided, That all such messenger services are confined to the territorial boundaries of the county in which an office of such financial institution is located or within fifty miles of an office of such financial institution.
(b) Upon the approval of the commissioner, a banking institution may establish one or more mobile facilities to accept or withdraw deposits, pay checks, issue cashier's checks, traveler's checks and other instruments, as well as perform other banking services. Each mobile facility shall be affiliated with and operated by a bank or branch office of a bank physically located and authorized to do business in West Virginia. All mobile facilities permitted hereunder are confined to the territorial boundaries of the county in which an office of such financial institution is located or within thirty miles of an office of such financial institution. A mobile facility shall be viewed as an extension of the qualified offices of the bank located in West Virginia and the transactions shall be governed by the laws applicable as if made at such offices. The term "mobile facility" shall include a mobile customer bank communications terminal which is intended to be moved or driven from place to place. A mobile customer bank communications terminal will be treated as an off-premises unit subject to mandatory sharing laws and rules notwithstanding any contrary provisions of this subsection: Provided, That no mobile customer bank communications terminal may serve as an automatic loan machine (ALM) terminal on behalf of any other institution other than the operating bank: Provided, however, That no mobile facility may be operated within two thousand feet of another bank's main office or branch office.
