How do engineering business choose Access control read card utensil?

          Door stops using 's not contact IC  Clip   (   Inductor type   IC  Clip   )   Reads card utensil is Access control systematic important component, Is Access control system signal incoming key equipment, Supposings that a Access control system than do a personal word, Reads card utensil then be just like people's eyes. Relate to whole Access control systematic stability. If a Access control system controller and electricity lock all good, If reads card utensil 's quality have problem, Same will cause door beat not open wait for situation, Affect engineering 's check before acceptance and usage.

Pays attention to item a:   Is purchase homemade read card utensil or import read card utensil?
          Real imports read card utensil, Technology comparation ageing, Product 's repairs again rate low, Appearance designs compare fine endure look.
Shortcoming is:   Product's price expensive, Serves have no homemade read card utensil in time, And must use form a complete set brand 's import IC card, Imports IC card also comparation costliness.
          Unless consumer appoints use some import brand 's read card utensil, Author suggestion uses homemade read card utensil, But certain will choose domestic quality reputation and service average not bad manufacturer supply 's read card utensil. Homemade reads card utensil 's exteriority this also have by leaps and bounds progress in two, Fast keeps up with international popular model.
Imports 's read card utensil is homemade read card utensil pricing   6-10  Time, Imports card price is homemade card 's   10-20  Time.
          Homemade read card utensil and card's core chip all are adopt overseas shoot frequently wafer fabrication 's, Domestic also not possess should domain's chip 's develop and throughput. Imports read card utensil suggest use   Inddala ( Motrola)   605  Model read card utensil and   HID  6005  Card reader, Relatively say sex price little good thaner can   .
          Many homemade reads card utensil do what you like paste a overseas not existent brand, Marks a habitat so-and-so country, Or has a false habitat prove, This kind of hangs sheepshead buy gou rou's matter many, Engineering business will advert. Does not spend accuse falsely money, Alsoes have no buy good product, Offends come many trouble.

Pays attention to item two:   Purchases accord with international normative   Wiegand  26bit  Card reader    
          Shoots frequently read card utensil now international passing joint protocol standard is   wiegand  26bit, There are part homemade and Taiwan read card utensil adopt   485  Or   ABA  Magnet a format. Or other   bit  Digit 's, Author suggestion adopts   wiegand26  Card reader, Imports read card utensil for example   Indala  HID  Waits for All abide should agreement, No matter homemade or imports manipulator almost   99%  All obeys should agreement, If adopt not normative joint agreement can are after 's system upgrade and maintain bring very big consist with sex problem, Also not suggests you purchase have many kinds output formats 's read card utensil, Avoids usage time cause disarrangement.
          Many kinds output formats 's read card utensil just manufacturer start from save develop plate making cost wait for commerce point of view consider but proceed 's enactment, Is not 's function powerful on real significance. Adopts accord with international normative   wiegand  26  's read card utensil can for you systematic stability and after replacing read card utensil   Upgrade   Maintains bring very big convenience.

Pays attention to item three:   Is adopt   ID  Clips read card utensil or   IC  Does clip read card utensil?
          ID  Clips read card utensil is only read not contact   IC  Clip 's be named, IC  Clips read card utensil is can read can write not contact   IC  Clip 's be called by a joint name   . ID  Clip and   ID  Clip read card utensil 's cost performance and induction distance get along well with in   IC  Clip and   IC  Clips read card utensil.
          Supposing that just be used for Access control and Timecard recording   Or park Uni-card System, Suggest use   ID  Clip read card utensil and IC card. If needs consist with not ration Expense Uni-card System can only adopt   IC  Clip read card utensil and IC card. ID  Clips market compare popular and sex price than good is   EM  Card. IC  Clip read card utensil and IC card suggestion adopt   PHILIPS  's   MIFARE  1  (   For short   M1)   Other   logic  Or   TI  TM  Clips market share deflection low, Not do suggest adopt.

Pays attention to item four:   Does not Shan from appearance come judge homemade read card utensil 's quality   .
          Domestic reads card utensil for the most part adopt public mold, Or plagiarizes overseas read card utensil exteriority. Mold is everybody in common use, Who all can buy outer shell, So even if same exteriority 's read card utensil maybe breed since different manufacturer, Serve and quality also are different.
          Engineering business must to read card utensil have a detailed understanding, Do not Shan from exteriority and price on proceed distinguish. Suggests engineering business from purchase Access control manipulator's place purchase read card utensil, Ordinary Access control manipulator manufacturer or can form a complete set sale or manufacture than quality standard close read card utensil.

So, How does judge a read card utensil 's quality?
          We think, Some homemade reads card utensil for seek manufacture low cost, Adopts cheater circuit substitute for shoot frequently base station chip, This kind of reads card utensil execute current big, Easy dead machine or cover damage, Not does suggest adopt. Suggest adopt adopt U2270B  Imports shoot frequently base station chip 's read card utensil can good some. Certainly, On the other hand also want from you before purchase 's manufacturer 's read card utensil 's half year above 's use time and repair again rate and should manufacturer 's quality standard and public praise come proceed judgement. Another, Reads card utensil is a kind of long use 's equipment, Certain will have prevent die machine's circuit proceed protection in circuit design, This point of also is want pay attention to 's.

Pays attention to item five:   Is adopt gluey or not do envelop gluey read card utensil?
          Suggests adopt not do envelop gluey read card utensil.
          Reason is:   Even if envelops glue, Buzzer or barenesses out microbus, Here enters water also can damage read card utensil. Envelops glue adopt 's material is colophony kind 's, Domestic ordinary all adopt handwork a glue solidify mix and not average, Domestic 's colophony material price cheap but quality not good, Long uses behind can have conductance, Makes read card utensil execute chaotic or die machine, Imports colophony price expensive domestic manufacturer ordinary not be willing to adopt, Allocates equally go each read card utensil want several pieces of costs.
          Besides, Envelops glue become some manufacturer 's"   Fig leaf " , Will be cheap circuit board design craft to cover rise, Even will repair again board restart a glue proceed sale. Besides, Envelops glue also not do adapt to equipment abstract heat, To reads card utensil 's performance also is influential. So, Unless special occasion ordinary have no necessary certain want adopt gluey read card utensil. Special occasion to read card utensil proceed some prevent water protect can.
