ZK8500R is a USB fingerprint scanner and card issue device that provides a simple and efficient way to register user fingerprints and card numbers with ZKTeco Software. This device can capture fingerprint image or read card serial number (ID/Mifare) directly and upload to the system by USB interface. ZK8500R would save money as it can work as ZK4500+CR10E+CR10M, and also can save time, especially when a high volume of users will be using ZKTeco systems on site.
