There are two real anti-counterfeiting labels in Mei Ting: "anti-counterfeiting code" and "heat-sensitive anti-counterfeiting label". After purchasing a marked Mei Ting product, consumers can log in to official website, Mei Ting, and enter the security code to know whether it is genuine or not. Mei Ting's thermal safety is slightly smaller than a coin with the word "Mei Ting" in the middle. After baking with a lighter for a period of time, when the temperature rises, the word "Mei Ting" in the middle will disappear. After the temperature dropped, the word "Mei Ting" reappeared. Mei Ting imitation has no anti-counterfeiting label, or the anti-counterfeiting label has no thermal effect.
