Every secondhand dealer, upon acquisition of any article either by purchase or exchange, shall complete transaction records, blanks of which shall be furnished by or approved by the Police Chief or his/her designee, stating the full name and address of the seller, the month, date and year on which the transaction took place, and a full and detailed description of each article so purchased or exchanged together with any applicable identification numbers, with the price paid therefor, and cause such record to be signed by the seller in person. Before recording this information, the secondhand dealer shall require reasonable written proof of the seller's identification in the form of a motor vehicle operator's license, military identification card, adult state-issued identification card or similar item. The relevant information in the record shall be electronically or otherwise reported to the Police Chief or his/her designee, together with a digital photograph of the article purchased or exchanged, within 48 hours thereafter, unless earlier electronically reported to a duly authorized police officer upon request. The Police Chief or his/her designee may require that notice of transactions be provided in an alternative manner or to additional locations. The secondhand dealer shall retain the record, including the photograph, in his or her possession for a period of not less than two years, during which time the record may be inspected at any and all reasonable times by any police officer. The secondhand dealer shall also keep a record of any purchaser of a secondhand item, together with a description of the item purchased.
