The PIN DualSecure solution embeds the PIN between two labels as securely as inside a safe.
 |
The bottom label is applied to the telephone card |
|
The PIN is printed on the bottom label |
|
The bottom label and the PIN are sealed with a scratch label |
|
Tampering causes the coat of ink of the bottom label, including the PIN, to detach from the substrate and stick to the scratch label. |
There is no possibility to access the PIN unnoticed.
