EM202 Cheap Serial USB System Capacitive Fingerprint Sensor 

HFSecurity EM202 Cheap Serial USBSystem Capacitive Fingerprint Sensor


Product introduction:

   This semiconductor fingerprint module uses semiconductor capacitive fingerprint sensor chip, 'living' fingerprint detection, wet and dry finger with strong adaption, high-resolution images, no distortion, good image quality. Semiconductor acquisition chip is with small size, low power consumption, high security. The module uses "Eddie Ward fingerprint algorithm"which is with the independent intellectual property rights, with small size, low power consumption, simple interface, high stability,small fingerprint template (496 bytes), large capacity fingerprint identification (3000 fingerprint response Time is less than 0.5 seconds), etc., can be very convenient to be embedded in the user system to form a fingerprint identification products,to meet customer needs. It supports for embedded systems, Windows systems and a variety of Android system equipment, uses standard USB / UART communication, with the SDK development kit, can easily achieve all customer’s needs on fingerprint recognition.

Aidi Wode special fingerprint recognition algorithm is very good, especially with self-learning function. During fingerprint recognition process, fused the latest fingerprint feature into the fingerprint database after verification successful, so that users could use it easier and easier.


The module also uses the most advanced human touch activation system technology, when the fingers touch the fingerprint collector window, the system automatically activate and collect than the fingerprint. Make your product more intelligent, you no longer have no space for mechanical buttons and distress, while also improving the overall appearance of your product and cleanliness.


  Features and Advantages

1) High image quality: use international renowned semiconductor fingerprint sensor, with high image quality
2) High performance and low power consumption: High-performance, low-power design with dedicated 32-bit high-speed DSP core processor.
3) Applicability: Fingerprint dynamic optimization algorithm, the algorithm can automatically adjust the parameters, have excellent adaptability of various types of fingerprints.
4) Features: Fingerprint input, image processing, feature extraction, template generation, template storage, fingerprint matching (including 1: 1 and 1: N), template delete and other functions
5) Calibration alignment: algorithm supports automatic calibration identification, support 360 rotation collection than on
6) Development is simple: single-chip structure, using standard UART / USB1.1 / 2.0 protocol, high integration, providing SDK
