Features of 125Khz RFID Cards

The proximity cards, also known as access cards, operate at a frequency of 125 kHz. When placed near a card reader, they transmit a signal to the access control reader.

Upon placement, the card’s unique number string is transmitted to the access control panel, where it is validated against approved card numbers (CSN) stored in the internal database.

Reading Range: Approximately 2-15 cm for contactless reading.
Material: Constructed from PVC to effectively protect the chip, providing durability, stability, and resistance to water and dust.
Operating Frequency: Utilizes passive RFID technology at 125 kHz.
Operating Temperature: Can function within the range of -20°C to 80°C, ensuring reliability in various environmental conditions.
