## Description
A US municipal public library system migrated 1.4 million catalogued items from a legacy 13.56 MHz proprietary chip to NXP ICODE SLIX2 (ISO 15693) RFID...

## FAQ
- Q: Can ICODE SLIX2 work with all major library kiosk vendors?
  A: Yes. Bibliotheca, Envisionware, FE Technologies, Lyngsoe and 3M Library Systems all support ICODE SLIX and SLIX2 as the default ISO 15693 chip family. Confirm with your kiosk vendor that the firmware supports the AFI bit operations for EAS. The customer in this case used Envisionware kiosks and Bibliotheca security gates.
- Q: How long does re-tagging take per item?
  A: 12–18 seconds per item including reading the existing barcode, writing the EPC field with the library's catalogue ID, attaching the label and updating the WMS. A trained paraprofessional retags 180–220 items / hour. A 35,000-item branch takes 160–190 staff hours to fully re-tag — typically completed by 4–6 staff over a 5-week window in off-peak hours.
- Q: Does the chip survive being checked out for months?
  A: ICODE SLIX2 EEPROM is rated for >50-year data retention at 70 °C, far beyond library temperature ranges. The mechanical failure mode is label delamination from the book paper after repeated wet exposure (children's-section books are the most vulnerable). The customer's specification calls for a 10-year minimum label-life expectation, and replacement labels are budgeted at 0.5% / year of catalogued items.
- Q: What happens to patron-privacy concerns?
  A: ICODE SLIX2 stores only the library's catalogue ID, not patron data — the patron's link is in the library's circulation system. The chip can be read at vicinity range, so a patron walking past a UHF reader could in theory have their book inventory detected. The library mitigated this by issuing privacy-aware book covers for any patron who requests one, which contain a thin foil layer that blocks the HF read.
