Lead seals have been developed for decades. The old-fashioned lead seals made of lead have just begun. Now there are many kinds of lead seals made of different materials. After so many years of development, there are many different types of lead seals, such as plastic lead seals, steel wire seals, high seal and so on. These lead seals can be used in different industries. What anti-counterfeiting technologies are commonly used in lead seals? ?

Laser Printing Bar Code: Look at the article "What's the Role of Bar Code on Lead Seal" written before the small edition, you will know why printing Bar Code on Lead Seal has anti-counterfeiting function. In fact, there is no anti-counterfeiting function in Bar Code itself, but when making, one of the original 8-digit Bar Code can be set as a check code, and the check code itself is based on the number of the whole batch of products. Specially made, each bar code will not be repeated. This makes it very difficult to prevent and control the whole batch of barcodes, so as to achieve anti-counterfeiting.

Laser Printing Two-Dimensional Code: The purpose of printing two-dimensional code on the lead seal is the same as that of printing barcode. Only two-dimensional code carries more information than barcode, and can read the information on two-dimensional code only through the software on the handheld terminal, which can effectively play the role of anti-counterfeiting.

Insert the RFID chip: Insert the RFID chip in the lead seal, the RFID chip has the unique identification code function in the world, and the chip can store a lot of information, can play a good anti-counterfeiting role.
