The governing body, or, in the case of school districts not issuing their own warrants, the governing body of the appropriate issuing officer, may provide that when funds are available for the payment of approved claims, the approval of claims for payment shall, without the issuance of any warrant, be authority to the custodian of its funds to pay the claims by check or electronic transfer. Registers and transfers shall contain substantially the same information as required by law to be maintained for a warrant.
