Why do We recommend K12 instead of SA-0109?As shown in the figure below, We have listed the main parameters of SA-0109 and K12. As you can see, K12 is a new machine with larger capacity and more versatile applications, but the price is indeed cheaper.While SA-0109 has been sold in the market for more than 15 years (even the end-users know the button price) it is a public model, that is, every factory can produce it, so there will be uneven quality levels and inconsistent prices. If you only pursue low prices, it is easy to buy products of poor quality. While K12 is our private model of S4A, which is not produced by others. We have been making access control machines for 12 years, so we can control the price and quality better. If you are interested, We will post product parameters, pictures, and working videos for you to see.Here are the parameters to compare, as below:ModelSA-0109K12 ✩✩✩✩✩✩Access MethodRFID card+PincodeRFID card+PincodeButton workPress Buttons Press ButtonsUser capacity1000 users2000 usersDimension120 x 78 x 22mm114 x 75 x 16mmVoltageDC12VDC12V-24VProgram password*999999*999999ProgrammingEasyEasyWiegand output NOYESThe product moldPublicS4A PrivateWait for your comments!Written by Teresa ZengFrom S4A INDUSTRIAL CO., LIMITED
