The security seal is stuck to the wrapping-foil in such a manner that the foil cannot be removed unnoticed. The hologram is an effective copy protection, while the predetermined breaking points prevent a nondestructive removal and thus, a reuse of the seal. In addition, the security color that glows under fluorescent light in combination with the 12-digit, continuous number (depicted as QR-code) make the security seal unforgeable.
Why a QR-code?QR-Code stands for „Quick Response Code“ and was developed by a Japanese company in 1994. It makes it possible to encode information in a way that it can be quickly decoded by a device. In contrast to the barcode, data can be encoded horizontally and vertically. Thus, the space available on the +Seal Manager Seal can be used optimally.
At +Seal Manager, we tested and compared both code versions: The QR-code is not only recognized much earlier by devices, but can also be scanned from a greater distance than a regular barcode.
The QR-code comprises an automatic error-correction and thus is also more resilient than a barcode. On the +Seal Manager Seal there is a QR-code with an error-correction level M, which means that 15% of the data can be restored.
