The world's thinnest optical fingerprint solution product details

1 Overview

The so-called fingerprint identification, as the name suggests, is to use the unique fingerprint information on the human finger to identify. As one of many biometric technologies, fingerprint identification has the following advantages: (1) Legal recognition, non-repudiation. (2) The characteristics of life and life. (3) Relatively low cost and small volume. (4) The longest development and the most mature technology. (5) Ten fingers, easy to use.

Fingerprint identification is the best way to balance security and convenience. Driven by Apple's mobile phone, the concept of fingerprint identification and related applications will enter more people's lives. For example, the fingerprint lock saves the trouble of having a key, and the car fingerprint remote control also allows the user to not have to worry about the remote control, the car being stolen, and the like. The future is expected to provide further checks on network security and payment systems.

2. Fingerprint identification device

A common fingerprint identification device can be composed of two elements: a processing chip and a fingerprint sensor. The early development of fingerprint identification is limited by the slow processing speed and high price of processing chips. With the rise of cost-effective and power-saving ARM processors, fingerprint identification can really enter the consumer market. The main purpose of the fingerprint sensor is to collect a complete fingerprint image. Commonly, there are two types of chip sensor (Chip Sensor) and optical type (OpTIcal). The size of the chip is small but the price is high and the image capturing area is small. Low, large image area, but large volume, each has advantages and disadvantages.

(1) In order to grasp the timing of product priority introduction, Holtek actively invested in fingerprint identification technology, combined with the investment strategy partner Jin Hao Technology, and then matched the Cortex-M3 MCU HT32F2755 for fingerprint identification, and completed ultra-thin optical fingerprint identification. The system caters to the current trend of miniaturization and low price.

(2) Holtek's optical fingerprinting machine is based on the patented "TrueSecureTM" 3D fingerprint identification technology. Through special materials and optical systems, it can obtain a sufficient effective area in a very short optical path and compress the thickness of the whole optical module to 6.5 mm (mm), and has the advantages of low price, large image area and small size of optical and chip type. The ongoing second-generation solution thickness further compresses the thickness to only 4.9 mm and has been favored by some of the specialized tablets, financial transactions and remote controls. The third-generation solution, which will be released in the fourth quarter of 2014, is even 3.0 mm thick, helping to attack the mobile device market, which is extremely focused on thin and light.

Holtek optical fingerprint modules can be divided into three categories.

The GT series (GT-5110E1/5120E2) is a parallel interface (Parallel Interface) fingerprint sensor. The original image data is sent to the external hardware through the 24-pin interface, which provides the algorithm manufacturer to further develop its own solution.

GTU series (GTU-5110B3/B4/B6) is a USB interface fingerprint sensor. Fingerprint image data can be transmitted to PC or mobile phone through USB interface. Holtek will also provide related drivers for major operating systems, such as Windows and Linux. .

GTM series (GTM-5110C2R/C3/C31/C5/C51) is an embedded fingerprint identification module, which mainly includes fingerprint sensor and Holtek Cortex-M3 MCU with embedded fingerprint identification algorithm, and can be simply UART or USB interface. It performs related instruction operations, such as file creation, comparison and deletion, to provide a fast and convenient method for fingerprint recognition. The GTM series can store 20, 200 and 2000 fingerprints respectively depending on its application.

4. Optical fingerprint module application

Holtek's various optical fingerprint modules are no longer limited to high security requirements, and are ideal for system products in different applications, such as tablet computers, smart phones, network identity authentication, notebook computers, rugged notebooks, Industrial mainframe, computer cash register, mouse, keyboard, external hard drive, finger disc, electronic door lock, car lock, access control attendance system, remote control protection, safe, safe deposit box, locker, gun cabinet / box and other related products .

The start-up battery is the soul of your vehicle.  It starts the Engine, and generates the energy necessary for the operation of all other vehicle's electric aspects. But did you know that it only has two years of life approximately?  Since during the unloading process and float charging, the battery's negative plate is sulphated fast, Reducing the functional capacity of the battery, until its complete inoperative. That's why we present the start-up Battery Pulse Protector. We offer you a fully automatic battery maintainer and protection system, it works 24 hours a day. Battery protector is not a battery charger. It is a patented electronic Sulfuric Crystal Cleaner which will eliminate the battery sulphation which is the main cause of problems and failures in lead acid start-up batteries. This battery pulse desulfator keeps the battery's condition as new, provides faster starts up your car or truck. Extends battery lifespan up to two or more times and reduce recharge time. Increase the capacity for your charge to last longer between recharges. Helps to protect the environments because it reduce the number of batteries that are discarded every year.

How is it installed? Lugs connect directly to the battery terminals.Easy Installation of 12V300Ah Battery Smart Pulse Protector

Designed especially for frequently-charged 12-Volt battery systems, the 12V Battery smart pulse protector and pulse maintainer ensures maximum performance on both single 12-Volt lead-acid batteries as well as two or three 12-Volt batteries connected in parallel.
