13.56MHz User Manual
1. Overview
KR6**D Series 13.56MHz is a non-contact RFIC card reader that is developed based on the ISO/EM4001
international standard protocol. It adopts the high-performance RF card reader circuit designed by ZKTeco.
It is characterized by the high integration degree, strong anti-interference capability, compact size, stable
performance, and cost effectiveness. KR6**D Series provides the Wiegand 34/66 communication
interface, and is applicable to various RF identification fields, such as the access control, attendance,
charging, anti-theft, and patrol systems.
2. Features
 The card reader is equipped with a card-reading antenna that works at 13.56MHz.
 The effective distance ranges from 0 to 5cm, depending on the working environment and card type.
 The data receiving time is less than 80ms within the effective distance.
 The card reader adopts the single +12 VDC power supply, and the operating current is less than
100mA.
 The data is output in the standard Wiegand34 bits format by default. The format can be converted
between Wiegand34 and Wiegand66.
 The card reader is produced using the fully closed rubber injecting operation to achieve the
waterproof and moisture-proof effects.
 The effective distance is associated with the voltage of the power supply, used IC cards, and operating
environment.
