1、Crack and Clone IC ID Card: Eliminate the blind area of close up card reading, stable reading and writing, and increase the parsing speed by 30%. 2、Built In HF Antenna: The depth of the antenna is matched, eliminating blind spots, and reading the entire card data stream without interruption. 3、Multifunction: Increase the rate of parsing keys, and the card size takes all. The sniffing data is complete and stable, and the error rate is low. 4、Low Frequency Antenna and USB Port: The low frequency antenna improves the signal to noise ratio and the recognition rate is higher, 2 USB ports: one for power bank and the other for offline sniffing. 5、Detachable Design: Meet various needs, no antenna interface, no need to plug and unplug, easy to damage.
