How choice Timecard recording machine?

      's adapts to medium and small enterprises use 's common Timecard recording machine approximate can divide into three kinds on market, Thats be electron beat cassette checking attendance clock, IC card Timecard recording machine and, Three kinds of products eaches have each 's good and bad points. How choice Timecard recording machine?

      Will Timecard recording machine want must to everybody all not strange, Will coming and going to work by Timecard recording machine punch in be many goes to work the race every days must dry job, Also is enterprise be used for check staff whether point stipulation come out diligent basis. Ases continual use 's product, How purchases appropriate Timecard recording machine is compare headache problem, Underside then let we come know once thises kind of can not be short of 's work product.

      's adapts to medium and small enterprises use 's common Timecard recording machine approximate can divide into three kinds on market, Thats be electron beat cassette checking attendance clock, IC card Timecard recording machine and, Three kinds of products eaches have each 's good and bad points.

A, Electron beats cassette checking attendance clock
      Electron a kind of punch machine and machinery punch machine all belong to punch in kind of product, Electron beats cassette checking attendance clock are many medium and small enterpriseses use most many Timecard recording machine, Also right and wrong always simple practical a kind of. Machinery punch machine ordinary fitting is used for on thousand peoples 's factory, Soes here we then not do overmuch introduction.  
      Electron a kind of punch machine at Timecard recording machine in, Set up print device, Passes use beat paperboard can direct print come out original Timecard recording record. This a kind of product's major advantage is intuitional clear, Punch in's situation clear at a glance, Not does need connect computer can single plane usage.  
      But usage time need consumption for special purpose beat paperboard, Sheet use then can not repetition take advantage of, Long-term uses need consume plenty of beat paperboard. And punch in's efficiency compare low, Stat complicated, Automatic failure rate compare high, Common fitting is used for 's medium and small enterprises 100 peoples below.

Two, IC card Timecards recording machine  
      IC card Timecards recording machine is at present use extensiver a kind of Timecard recording machine, It adopts IC card do Timecard recording card, Clip and machine have not mustache contact, Only needs nearness and then be OK proceed Timecard recording.  
      It principle of operation is: Ases card nearness time, Reader/writer to card sends a group of fixed frequency's electromagnetic wave, 's LC resonance circuit brings forth resonate in card, Thus makes have charge in capacitance, Accumulates 's charge reach 2V times, This capacitance for other circuit supply operating tension, Will clip in data shoot go out or meet take reader/writer's data, Finishes Timecard recording process.  
      IC cassette's Timecard recording machine Timecard recording celerity, Convenience, Averages Timecard recording an individual only use 0.1 second and then be OK finish, And uses 's IC card can repetition take advantage of. Buts IC card Timecard recording machine read data must connect computer, Can not intuitional show out. And will fit special IC card talent usage, But IC card price at several yuan about, Calculates down also is a sum of many expenditure.  
      Towards staff number at several hundred people's company units, Adopts IC card Timecard recording machine is compare high power way of doing, Complete has canned at short in record all staff 's turn out for work situation for several minute.

Three, Fingerprint Timecards recording machine  
      Fingerprint Timecards recording is develop rise 's new technology lately in several, At present uses compare many at gao Xin secret enterprise, Also have not cover huge amount of adopt at common company.

      Fingerprint style Timecards recording machine principle of operation: Will take advantage of each personal fingerprint mutual not same principle, Establishes fingerprint warehouse, A each staff's fingerprint and name wait for staff information hook. Staff coming and going to work all must point fingerprint, Fingerprint Timecard recording machine a collect 's fingerprint and fingerprint warehouse contrast, Again to corresponds to fingerprint record 's staff proceed record examination.

      This kind of Timecards recording style can effective avoid a generation punch in's phenomenon, And has not must card wait for consumes the material, As long as purchases machine connect computer can start usage. But its shortcoming also same obviously: At starts want collect staff's fingerprint, Very trouble. And recognize rate not high, Easy incurs many factors 's disturbance, Is like come out sweat, There is static.

      Should chooses what kind of Timecard recording machine, Everybody at look introduce behind psychology should have check the number.

      Company scale compares small, Personnel changes compare big enterprise, Chooses electron beat cassette checking attendance clock can; But medium scale, To Timecards recording have high power requisite enterprise can choose IC cassette Timecard recording machine; There is special need, Make a point ofs keep secrecy sexual unit can try use fingerprint Timecard recording machine. Buts no matter choose what Timecard recording machine, Zou shi accurately, Timecards recording data not easy incur disturbance, With computer communication stabilizes this several points of all is must consider 's.
