Description

Technical field [0001] The invention relates to an anti-counterfeiting signature seal, in particular to a battery plug-in anti-counterfeiting signature seal that can be reused and can read information. Background technique [0002] In the financial system, packing boxes or bags are often used to hold and transfer coins or banknotes, and zippers are installed at the openings of the packing boxes or bags. When bank staff perform traditional operations, handover or bagging, they need to unzip the zipper, put the money bundle into the bag, close the zipper, and seal the slider at the closed position. For example, a safety stop device disclosed in the Chinese utility model patent number ZL200720095194.3, which positions the slider on the zipper inside the groove on the fixed box, and then covers it with a movable pull cover and uses a safety lock piece Fix the fixed box and the movable cover together, once the front part of the safety lock piece is inserted into the inside of the fix...

AI Technical Summary

Problems solved by technology

However, when the slider needs to be pulled, the fixing box and the movable sliding cover can only be separated from each other and the slider can be pulled by breaking the fold of the safety locking piece to destroy its structure. Therefore, the device can only be used once. high cost and low efficiency
