We have a proprietary system of security seals, which operates an unprecedented and highly secured system using special technologies such as barcodes based on the data required in the seal. Numbering (serial numbers) may also be added to the seal to enhance immunization. All institutions can be provided with this type of seals to immunize the documents and letters issued by them from any forgery or breach. Through the security label, messages can be filled with ensuring that they are not opened or tampered with because the indicator will indicate the (open) sign if it is opened or attempted to be opened.
