Now selling gold is to show your ID card for registration. The jewelry industry will have national industry standards in the aspects of gold jewelry repurchase and replacement, gold shop operation safety prevention, etc. Individuals must register their ID cards when selling jewelry. In order to prevent stolen goods from being sold, jewelry stores should inspect the recovered gold and silver jewelry or jade jewelry, record its basic characteristics, source and destination in detail, register the name of the unit selling the jewelry or the identity card of the individual, and file it with the trade association. The filing system can crack down on possible illegal and criminal acts in the recycling process. Even if it is not found at the scene, it is well documented after the public security intervention.
