Accessories

189607000 are accessories used to provide additional services and functions, such as enabling people to interact with digital devices more conveniently or providing more accurate results for application scenarios. They can be divided into two categories: field and working principle.

Fields

The 189607000 accessories in this field mainly include Barcode Scanner, Magnetic Card Reader, Rfid Card Reader and Card Terminals, Passport Reader, OCR Scanner, Long Range Reader, etc., which are applied in Automotive Assembly, Financial Institutions, Education, Retail Business and Transportation, etc. These accessories all help people accurately read and collect data from devices that are difficult to read manually, thereby improving people\'s working efficiency.

Barcode Scanner is widely used in retail stores, supermarkets, express delivery, etc. It can identify a variety of barcodes quickly with high precision and accuracy. Magnetic Card Reader is mainly used in financial sector, as it can read information from cards with stripes such as bank cards or credit cards. RFID card readers can provide access control applications for personnel management. The passport reader is mainly used for project identification, such as boarding identification and identity verification. OCR scanner, as its name implies, helps people quickly scan words in paper or printed text with an accuracy of 99%. Long range reader is mainly used to collect and manage the information of personnel and vehicles, so as to provide visualized prompts and warnings.

Working Principle

The 189607000 accessories can accurately read data due to its advanced technology. Among them, the Barcode Scanner mainly adopts the reflective scanning method. When the laser is projected onto the surface of the barcode, the laser reflected by the barcode can be received by the photosensitive device. Magnetic Card Reader mainly adopts integrated coils to identify the data stored on the magnetic stripe and convert it into electrical signals that can be read by the processor. The RFID card reader mainly adopts the principle of electromagnetic induction. It emits electromagnetic waves to the RFID card to receive the radio frequency signal transmitted by the card, so as to read the embedded information. The passport reader mainly uses dual galvanometer mirror scanning technology. The reader will scan the passport chip area. Under the control of the processor, the driver sends a reflective optical signal to the inner chip of the passport for laser focusing and reading. OCR scanner mainly adopts the principle of monochrome imaging. The monochrome imaging device output can be reflected to the processor, and the processor will complete the restore and identification operation of the information. The long range reader mainly adopts the time-domain reflectometry technology. It adopts the principle of sending an electromagnetic signal with a specific frequency and using the receiving device to receive the rebound signal, and then analyze the two signals according to the laws of physics.

In short, 189607000 accessories have made it possible to accurately read data from digital equipment, providing more convenient access to people and enabling more accurate application results. Through understanding the application field and working principle of the 189607000 accessories, we can better understand their advantages, improving our application level.
