125 kHz RFID Key Fob 100 Pack Blue

This pack contains one hundred blue 125 kHz RFID key fobs for proximity access control systems. Each fob arrives pre-programmed with a unique 10-digit ID engraved on the casing. They work with unencrypted 125 kHz readers and universal tags such as EM4100 and EM4102. Buyers needing 13.56 MHz or encrypted credentials cannot use these.

Operating Temperature Range and Durability

The fobs operate from -25 °C to +75 °C and store safely between -15 °C and +45 °C. Data retention is rated for ten years with anti-interference protection. Each tag supports up to one hundred thousand wiping cycles and reads at distances up to 10 cm. No batteries or active electronics are involved.

ABS Plastic Build and Keyring Mounting

Each tag measures 1.4 by 1.1 by 0.2 inch and uses blue ABS plastic for a lightweight, rigid shell. The compact shape fits standard keyrings for everyday carry. The surface resists casual abrasion and the engraved ID remains legible after extended use. No adhesive or screw mounting is required.

Questions about this item

How do I add these 125kHz key fobs to my access control system, and what step do people often miss?

Confirm your reader uses unencrypted 125kHz and supports EM4100 or EM4102 tags; the step often missed is checking that the system is not locked to encrypted formats like HID or Indala.

What maintenance or replacement will these blue ABS fobs need over time?

The chips retain data for 10 years and survive 100,000 wipe cycles; the ABS casing may eventually crack from physical wear, at which point you replace the fob.

What is the first limit I will hit if I scan these fobs continuously at the 0-10 cm range?

The 100,000-cycle wipe-life rating is the first hard limit; operating temperature (-25 °C to +75 °C) and read distance are not consumed by repeated scans.
