Notwithstanding any other provision of law a credit union may establish share and deposit accounts payable to one or more persons during their lifetimes and on the death of all of them to one or more payable-on-death payees. An account established under this section must be identified as a "payable-on-death" account or abbreviated as a "p.o.d." account. Any transfer to a payable-on-death payee is effective by reason of the account contract and shall not be considered to be a testamentary transfer.
