EM and RFID can both protect library collections, but they operate very differently. EM is primarily a security-strip workflow. RFID can combine item identification and security status, which opens the door to self-service, faster inventory and more integrated patron workflows.
RFID vs EM at a glance
| Area | EM security | RFID library workflow |
|---|---|---|
| Item protection | Electromagnetic security strip | RFID tag with security workflow |
| Item identification | Usually barcode remains separate | RFID can identify item and security state |
| Self-service | Possible with compatible deactivation/reactivation workflows | Strong fit for integrated selfCheck workflows |
| Inventory / shelf work | Barcode-centric | RFID enables faster collection scanning workflows |
| Migration impact | Lower change if existing EM estate is serviceable | Requires tagging, integration and phased operational planning |
When EM still makes sense
An existing EM library may not need immediate replacement if the detection system, security strips and circulation process remain serviceable. Bibliotheca continues to reference Tattle-Tape security strips as a supported EM protection route for libraries migrating from retired Highland strip families.

What RFID changes
RFID can support integrated self-service, inventory, item handling and security. Bibliotheca's current self-service ecosystem includes RFID-based checkout workflows and mobile options; this makes RFID a broader operational platform rather than only an anti-theft technology.

A phased migration can be safer than a big-bang replacement
Many established libraries cannot retag an entire collection or replace every counter, gate and self-service point at once. A practical migration may retain selected legacy equipment temporarily while introducing RFID in phases. The sequence should be planned around the ILS/LMS, item tagging, staff workflow, patron disruption and supportability.
What PNSS audits before recommending a migration
- Existing gate, workstation, self-service and book-return models.
- Current EM strips, RFID tags and barcode workflow.
- Library management system integration method.
- Collection size and realistic tagging manpower.
- Entrance width, accessibility and power/network availability.
- Which legacy equipment can remain temporarily without creating workflow conflicts.

Specifications and product positioning should be reconfirmed against the current manufacturer documentation before final quotation.
