1.Built-in high-frequency antenna, antenna depth matching, eliminate blind spots, read the whole card data flowing without interruption. 2.Increase Parse the secret key rate , the size of the card takes all. 3.Sniffing data, complete stable, low error rate. 4.The low frequency antenna to improve the signal to noise ratio, the higher the recognition rate. 5.No antenna interface, did not need to plug. Because it is easy to . Power by Usb port, simple and convenient. (can use mobile power supply) Warning: This does NOT have quick-swappable/detachable antennae.
