1. Built-in high-frequency antenna, matching antenna depth, eliminating blind spots, reading the entire data card without interruption. 2. Increase the frequency of the key, the size of the card can accommodate everything. 3. Data analysis, completely stable, and low error rate. 4. The low frequency antenna improves the signal-to-noise ratio, the recognition speed is higher, and the mobile design can meet needs. 5. No antenna interface, no need to connect because it is easily damaged. Cancel lithium battery, easy and convenient.
