All books and records required to be preserved by any regulation of the commissioner or required by any federal statute, regulation, or regulatory guideline, as applicable to each registrant, shall be preserved and made available to the commissioner, as provided in this chapter, for a period of twenty-five (25) months on all rejected applications and for a period of twenty-four (24) months on loans paid in full. The registrant may cause any or all records at any time in its custody to be reproduced or preserved, or both, by itself or by any other person who agrees in writing to submit its operations to the examination of the commissioner to the extent that the operations directly affect recordkeeping by any microphotographic process, electronic or mechanical data storage technique or any other means. A record reproduced or preserved, or both, by those processes, techniques or means shall have the same force and effect as the original record and be admitted into evidence equally with the original.
