ICODE SLI can't be switch to ICODE SLIX

My client has been using the ICODE SLI chip I provided, but this chip has been EOL. We are trying to switch to the ICODE SLIX, but the client's RFID reader cannot recognize it.

Hello,

ICODE SLIX is intended to be backward compatible with ICODE SLI at the ISO15693 level, so the reader should at least detect the SLIX UID during inventory. If the reader cannot recognize it, please first check whether the failure is at RF inventory level or in the application’s tag-identification logic. Common causes are AFI/UID filtering, hardcoded SLI product recognition, old reader firmware, or use of SLIX-specific security/features during migration. For the first test, disable AFI filtering and tag whitelisting, perform a standard ISO15693 inventory, read UID/DSFID/AFI, then compare the application’s acceptance logic against the old SLI tag.
