1. Built-in high-frequency antenna, matching antenna depth, eliminating blind spots, reading the entire data card without interruption. Increase the frequency of the key, the size of the card can accommodate everything. Data analysis, completely stable, and low error rate.The low frequency antenna improves the signal-to-noise ratio, the recognition speed is higher, and the mobile design can meet needs. 2. No antenna interface, no need to connect because it is easily damaged. Cancel lithium battery, easy and convenient. (In offline mode, you can use mobile power). Except that it has to do with the old relay, it has low cost, light weight and easy to carry. Compatible with all official firmware, can clean any version as needed. Depending on your preference, you can use the official " line" or "Proxmark Tool.exe" to work 3. DOUBLE port usb. From AT91SAM7S256 to AT91SAM7S512. (Low-frequency antenna is installed on the right) Antenna LF: 30.41 V 125.00 kHz; Antenna LF: 22.01 V 134.00 kHz; HF antenna: 28.43 V 13.56 MHz; (Low-frequency antenna is installed on the left) Working voltage:3.5-5.5V, Current work: 50-130mA 4. NOTE:The phone stickers and glue cards in the product pictures are sent randomly without remarks. The new machine shows v3, which is a printing problem. You can directly flash the v5 firmware without affecting the use. Please note. Card operation mode: 1. Ordinary M1 S50 card reader and other Type B 14443A cards 2.
