D. An authorized representative of a drawee financial institution may certify bank records that are obtained by subpoena if all of the following apply:
1. The bank records are the regular account records that are used and kept by the drawee financial institution.

3. The bank records are made from information that is transmitted by a person who has firsthand knowledge acquired in the course of the drawee financial institution's regular course of business.
E. At a trial for a violation of section 13-1802, 13-1807, 13-2002 or 13-2310, certified bank records that are obtained by subpoena may be introduced in evidence and constitute prima facie evidence of the facts contained in the records.
F. At a trial for a violation of section 13-1802, 13-1807, 13-2002 or 13-2310, an affidavit of dishonor may be introduced in evidence and constitutes prima facie evidence of either:
1. The refusal of a drawee financial institution to pay a check because the drawer had no account or a closed account with the drawee at the time a check was issued or passed.
2. The refusal of a drawee financial institution to pay a check because of insufficiency of the drawer's funds at the time a check was issued or passed.
G. A certification of bank records or an affidavit of dishonor that is acknowledged by any notary public or other officer who is authorized by law to take acknowledgments shall be received in evidence without further proof of its authenticity.
