Made of fine quality material, practical, easy to operate and use, wide application range, has a long service life. Features: Built-in high-frequency antenna, antenna depth matching, eliminating blind spots, reading the whole card data flowing without interruption. Increase parse the secret key rate, the size of the card takes all. Sniffing data, completely stable, low error rate. The low frequency antenna improves the signal to noise ratio, has a higher recognition rate, and is detachable to meet various needs. No antenna interface, no need to plug, because it is easy to damage. Cancel the lithium battery, simple and convenient. (Offline can use mobile power source) In addition to the former relay and other unrelated, lightweight and portable. Specifications: Material: PCB Color: black Operating voltage: 3.5-5.5V Working current: 50-130mA Sensing distance: 30-50mm / 1.2-2.0in Card reading time: 0.2s Capacity: 512M Item size: 86.6 * 54mm / 3.4 * 2.1in Package size: 152 * 102 * 40mm / 6.0 * 4.0 * 1.6in Package weight: 188g / 6.6ounce The main function of (common): High frequency: Operating card mode: 1. Conventional M1 S50 card reader and other 14443A Class B card. 2. Use the PRNG vulnerability parsing sector 0. 3. Use nested (mfoc) vulnerability resolve the whole card. Analog card mode: 1. Analog Mi series S50 / Ultralight / DESFire card UID. 2. Analog M1 S50 whole sector data. (Pick a card reader) 3. Analog M1 S50 housing, to obtain data to calculate the secret key (pick a card reader). Silent mode: 1. Silent sniffer data communication between the M1 S50 card and card reader, analytical secret key. 2. Silent sniffing 14443A Class B card reader with a complete communications data. Reader device can be used for debugging and behavior analysis. Low frequency: Operating card mode: 1. Read T55XX, Indala and other low-frequency cards. 2. By T55XX card write Indala, turned into three cards. Analog card mode: 1. Enter card, analog to the specified card type. 2. Analog modulation schemes specified data cards and ASK / FSK / PSK. Silent mode: 1. Silently sniff data between the card and the reader (less, not tested). Note: 1. Need to download the software yourself. 2. USB color is shipped randomly Package list: 1 * Card Reader 1 * USB Cable 3 * 13.56MHz UID Card 1 * CUID Card 1 * S50 Keyfob
