fingerprint encryption is the acquisition of computer hardware information. We need to read the machine identification one by one through a program and use certain algorithms to restrict user authorization based on the machine identification.
Common hardware resource package: Hard Disk Physical serial number, CPU serial number, Nic MAC address, BIOS serial number, and motherboard serial number. If your har

With the RX470 graphics card officially listed, these performance is second only to the RX480 and the relatively inexpensive graphics card has been favored by some players and attention. As a graphics product positioned slightly below 480, RX470 is very similar in design to RX480, with the main difference being the streamlining of some core specifications. So what's the problem, RX470 with what CPU and motherboard
