I am using ICODE SLI for protecting our consumables.
768 bits RSA signature was written int the tag based on the UID and consumable type.
I thought that is enought to protect from copying our consumables.
But, someone made compatible consumables by copying our tag including UID.
I found UID changeable ICODE SLI tag in China market(Alibaba).
It means that anyone can make copy tag despite RSA signature.
I am considering changing tag to ICODE SLIX2 or ICODE SLI-S.
But, If there is uid changeable tags for these tags, it is meaningless.
My question is:
1. Is there uid changeable ICODE SLIX2 or SLI-S ?
2. How much easy to make uid changeable ICODE SLIX2 to SLI-S?
3. Which(SLIX2, SLI-S) is more diffcult to make uid changeable tag?
I am very appreciative any comments.
