What’s more, here are a few reasons for electronic code locks’ popularity. For one thing, nowadays, electronic code locks can be customized specifically according to individual needs. For instance, confidentiality function, password error alert and changing password, etc. For another, there are more functions which can be applied accordingly, such as fire alarming, reminding the lack of electricity and automatic locking,etc. Thanks to the significant progress of technology, some manufacturers are able to produce cost-effective electronic locks which are simply based on chips and circuits. In short, the electronic code lock will apply to each family gradually.At present, some code locks based on the micro-controller in the market cannot hold a candle to those which are based on FPGA both in performance and safety. Since micro-controller is poor i
