What types of information is the data encryption technology of the barcode scanner mainly used to protect?

1.Product information
1.1 Product details: When the barcode scanner scans the product barcode, it will obtain detailed information such as the product name, model, specifications, production date, shelf life, manufacturer, etc. Encryption technology can prevent this information from being stolen or tampered with during transmission, and protect the legitimate rights and interests of merchants and consumers.
1.2 Price information: The price of the product is one of the trade secrets. Through encryption, the accuracy and confidentiality of price data can be ensured to avoid price tampering, resulting in damage to the interests of merchants or consumers paying the wrong amount.

2.User information

2.2 Payment information: When the barcode scanner is used for mobile payment, it will involve sensitive information such as the customer's payment account, bank card number, password, etc. Data encryption ensures the security of these payment information during transmission and processing to prevent payment risks.

3.Transaction information
3.1 Order details: After the barcode scanner scans, the product list, quantity, total price, transaction time and other information in the order will be encrypted and transmitted. This helps prevent the order information from being tampered with or intercepted midway, and ensures the integrity and accuracy of the transaction.
3.2 Logistics information: In the logistics industry, barcode scanners are used to scan package barcodes to obtain information such as logistics order number, shipping location, receiving location, transportation status, etc. Encryption technology can ensure the security of these logistics information and prevent problems such as package loss or theft caused by logistics information leakage.

4.Internal information of the enterprise
4.1 Inventory information: In warehouse management and inventory counting, barcode scanners scan product barcodes to obtain information such as inventory quantity and in and out time. Encryption technology protects the accuracy and confidentiality of inventory data and prevents competitors from obtaining the company's inventory situation.
4.2 Production information: On the production line, barcode scanners are used to scan the barcodes of raw materials, semi-finished products, and finished products to record production batches, production dates, process parameters and other information. Data encryption ensures the security of production data and avoids interference with the production process.

5.Other sensitive information
5.1 Medical information: In the medical field, barcode scanners may be used to scan barcodes of drugs, medical devices, patient medical records, etc. Encryption technology can protect medical privacy information such as patients' conditions, treatment plans, and drug use records.
5.2 Government and public institution information: Government departments use barcode scanners to scan various certificates and document barcodes in the process of certificate management, administrative approval, public services, etc. Encryption technology can prevent government information leakage and ensure national security and social stability.
