X638 (TCP/IP) is a high-performance, network, double recognition engine offline fingerprint attendance machine with international appearance design. According to the different fingerprint distribution (old people, children, men, women, northerner, southerner, broken fingerprint, etc.) the machine has a good recognition performance. there are more than 40 million people use records, in more than 30 countries Use History. It Can store 2200 fingerprint, article 80000-100000 record, no need to real-time computer connection, is specially designed for fingerprint attendance according to need to remote offline use of enterprises and institutions. at the same time, it also applies to all kinds of only need accurate identification on various occasions. Fingerprint attendance machine connects with the computer through RS232 and RS485. It is suitable the enterprise within1000-2200 people, by the TCP/IP interface, it can easily realize the local area network dispersion centralized attendance and human resource.
