Solution for Anti - counterfeiting Detection Equipment of ID Cards
I. UV LED Waveband and Function
In the anti - counterfeiting detection equipment of ID cards, the ultraviolet wavebands emitted by UV LEDs are mainly UVA (320 - 400nm) and UVB (280 - 320nm).
The UVA waveband has moderate energy and can stimulate the specific fluorescent anti - counterfeiting materials on the ID card to emit visible fluorescence. These fluorescent materials are distributed throughout the ID card. When irradiated by UVA, the fluorescent anti - counterfeiting marks appear, which assists in identifying the authenticity, and it is relatively safe for humans and equipment.
The UVB waveband has a role in special anti - counterfeiting techniques. Some ID card anti - counterfeiting designs utilize its property of triggering photochemical reactions to produce color changes or new fluorescent marks, providing a basis for identification. However, due to the potential harm of UVB to the human body, the equipment has strict protective measures.
II. Product Overview
The anti - counterfeiting detection equipment of ID cards is a high - tech instrument used to identify the authenticity of ID cards, adopting UV LED and other multiple technologies. The equipment is compact and portable, suitable for places such as airport security checks, hotel registrations, and bank counters. Its casing is sturdy, and the operation interface is simple. Non - professional personnel can also quickly and accurately detect the anti - counterfeiting features of the ID card and judge its authenticity.
III. Scheme Principle
Fluorescence Excitation Principle
The fluorescent anti - counterfeiting materials on the ID card can absorb ultraviolet rays in the UVA waveband and emit visible light. When irradiated by UVA, the electrons in the materials absorb energy and make transitions. When they return to the ground state, they release energy to form fluorescent patterns. The authenticity is judged by detecting the characteristics of the patterns and comparing them with the database.
Photochemical Detection Principle (for Special Anti - counterfeiting)
When UVB irradiates the special anti - counterfeiting parts, it triggers photochemical reactions, causing changes in the material structure and producing observable phenomena. The equipment captures these changes through sensors, judges the authenticity of the ID card based on algorithms and standards, and at the same time, the optical imaging system scans the ID card and gives a comprehensive analysis result.
IV. Customization Process
Demand Analysis
Communicate with the users to understand the requirements for detection speed, accuracy, operating environment, portability, compatibility, etc., and collect the anti - counterfeiting features of different versions of ID cards.
Design Stage
Design the layout and parameters of UV LEDs, the optical imaging system, the overall structure of the equipment, develop background processing software, and establish an anti - counterfeiting feature database and algorithms.
