1. The detection card can crack domestic fully encrypted cards that Proxmark cannot crack. 2. Can detect passwords for multiple sectors simultaneously! 3. Can crack ACR122, Proxmark3, Icopy3 and other devices that cannot be cracked for a long time. 4. The detection card can upload card dump data, store 8 cards with 1-4K capacity, and perform card communication simulation. Easy to carry! That is, one machine can be used as eight IC cards! 5. Built-in button battery, long standby time, convenient and easy to use. Graphical operation on the host computer is simple and intuitive, and detection results are calculated automatically! Is a helping decryption device. It is different from conventional copying machines. Conventional copying machines decrypt the card, while it detects the password in the card reader. Does not have the ability to write to the card itself and can only detect the password. The obtained password can be used by copying machines with decryption functions such as 122 or pm3 Color: Black Material: ABS Package Contents: 1 * Access Control Detector 1 * Data Cable Only the above package content, other products are not included.
