Deya series of stand-alone fingerprint identification module is the introduction of Deya R & D and manufacturing of small size integrated fingerprint module. To SynoChip high-speed DSP processor core, combined with the company's proprietary optical fingerprint sensor, without host computer in the management of cases, with a fingerprint input, image processing, fingerprint matching, search and template storage functions such as intelligent module. Users can conduct secondary development can be embedded into a variety of end products, such as: access control, attendance, safe, car door locks and so on.

Fingerprint Professional Development Series:

 DY-200 series fingerprint identification module is launched in Germany and Asia's semiconductor fingerprint modules, the series products have ultra-high security features, application of live fingerprint detection technology, effectively put an end to fake fingerprints, solving biometrics industry For the live fingerprint technical problems. At the same time, these products of the dry, wet fingers, also has very strong adaptability to the fingerprint ridges are not clear, incomplete fingerprint lines also have a very strong correction and fault tolerance, recognition rate is much higher than similar products, able to adapt to a variety of the weather and all kinds of people to use.

Product is imported semiconductor fingerprint sensors, high-speed DSP processors, high-performance fingerprint matching algorithms and other hardware and software structure, function very well, both fingerprint, fingerprint registration, fingerprint matching and fingerprint search capabilities, using the performance is very stable, has been are widely used in finance, transportation and other fields.

Applications: can be embedded into many types of end products, such as:

information security products, Access Control category

safe (cabinet) class type

POS machines cabinet

bullet Car fingerprint products

product features:

fully functional independent to complete fingerprint, fingerprint registration, fingerprint matching and fingerprint search capabilities

  security is good: live fingerprint detection capability, with pairs of fingerprints, false fingerprint recognition capabilities.

  adaptable: algorithm performance, various types of fingerprints have excellent adaptability, trunks of most trees fingers, wet fingers, light texture and so on fingers high recognition rate and a good correction, fault-tolerant performance.

antistatic ability: antistatic ability, dry and easy on the environment of the region, particularly from static to adapt to.

application development is simple: the developer without requiring fingerprint identification expertise, can provide control instructions. Fingerprint-based applications on their own product development.

small size: The sensor thickness is small, small size, flexibility in space-constrained embedded into a variety of products.

Sincerely service  for you,  look forward to long-term cooperation

Works fingerprint

processing consists of two processes: fingerprint logon process and the fingerprint matching process [which is divided into fingerprint matching fingerprint matching (1:1) and fingerprint search (1: N) in two ways]. Fingerprint log on, a fingerprint for each entry two times, two times the input image processing, synthetic templates stored in the module. Fingerprint matching, through the first fingerprint sensor, input fingerprint images to verify and process, and then with the module matches the fingerprint template comparison

(If the module specified in a template matching, called the fingerprint matching method, that is 1:1 approach; if matched with multiple templates, called the fingerprint search methods, namely, 1: N mode), the module is given match results (pass or fail)

Software Development

1: Make sure the module normal

Scenario  1: Give the module after power-receive modules take the initiative issued 0x5555, can be confirmed that the module is working correctly and is waiting to receive the command state.

 Scenario 2: In the uncertainty case, the module can send a Free instructions for communication handshake, received response packet, affirming that the module normally.

 2: Fingerprint login enroll fingerprint login to use instructions, there are two methods:

Method 1:

Step 1: First use of parameter 1 (ie), the user slide a finger rub received OK response to switch the next step, otherwise repeat step 1;

 Step 2: Re-use of parameter 2 (ie), the user rubbing the user fingers sliding received OK response that login is successful, otherwise repeat step 2 until successful.

Method 2:

Step 1: Direct use of parameter 2 (ie), the user slide a finger rub received responses failed to switch the next step (which should not receive the OK response, unless the position has been finger current template), if the receipt of a finger image bad (0x21, 0x22, etc.), repeat step 1;

Step 2: still use the parameter 2 (ie), the user rubbing the user fingers sliding received OK response that login is successful, otherwise repeat step 2 until successful.
