Each RFID Key Fob Tag EM-4200 has a unique 10-digit ID, so multiple tags can be used in a single project. This tag may be used for identification, access control to spaces and equipment, and for triggering other events in an automated system.
RFID Key Fobs are the ideal identification solution for personnel applications where the tag can be secured to a key chain, etc. These tags perform even better than they look.
