Wireless Voting Unit BJ-W5


♦ Unique wireless on-site online environment detection and frequency selection, ensure the system avoid any interference;
♦ Two registration ways, button pressing or inserting card.
♦ Software customized voting or evolution ways
♦ OLED display screen, humanistic human-machine interaction
♦ Automatic alarm when the system is faulty
♦ Low power consumption, low emission power, comply with the global electrical design and communication design standard
♦ Lithium battery or AAA battery, real-time detection of battery level, dynamic display, low battery alarm
♦ Automatic memory of voting result when power cut off
♦ Isolated touch switch, anti-30000V electrostatic interference
♦ Anti-violation and it can normally operate after dropped from 2 meters high
♦ Software can turn off all voting units together
♦ Immune to mobile signal jammer
♦ Utilize wireless digital communication way



♦ Attendance Registration: inserting card, key-press, supplementary registration; late delegate can vote supplementally; count “ number of supposed attendance”, “number of real attendance”, “number of absence”
♦ Voting: delegates can vote for “Yes” “No” “Abstain” or the customized voting way by the software.Computer automatically collect statistic and display the result.
♦ Single voting and multiple voting
♦ Effective first press-key or effective last press-key
♦ Election: elect one or more from candidates with the support of “single-candidate election” and “multi-candidate election”
♦ Evaluation: four buttons to evaluate. It comes with four choices “Good”, “Fair”, “Poor”, “Abstain”, or the customized evaluation way by software.
♦ Grading: From 0-100 points, the initial score is 80 points, press “Yes” to increase points and “No” to reduce poins.
♦ OLED Dynamic display of the voting process ( such as “ registration please, registration done, voting please, voted , please return” and etc)
♦ Multiple encryption and err correction during the data transmission
♦ Unified shutdown by software or automatic shutdown when it has not received signal for 4 hours, ensure the voting process by avoiding human misoperation
