Do you know about the read and decoded system of USPS tray label? Let you know about this: USPS tray label barcode is a type of barcode used by the USPS to track and sort mail trays, providing information about the contents, routing, and sorting. To read and decode this barcode, a barcode scanner is required.Barcode scanners are electronic devices that use a light source and a photosensor to read and decode information encoded in a barcode. They are used to scan USPS tray label barcodes, where the light source illuminates the barcode and the photosensor detects the barcode pattern.The scanner detects a barcode and employs a decoding algorithm to convert the pattern of bars and spaces into encoded information, determining the decoding method based on the barcode's structure, formatting, and specific symbology.The decoding algorithm uses specific rules and formats to extract encoded information from barcode data. For instance, the Mailer ID data element, a six-digit number, uniquely identifies the mailer. The same process is used for the Service Type ID data element, a three-digit code that identifies the type of service used, such as Priority Mail or First-Class Mail. Scanning process of tray label barcodes: *Obtain a barcode scanner: A handheld laser scanner is commonly utilized for scanning tray labels, as it can read both 1D and 2D barcodes. *Position the scanner: Position the barcode scanner close to the tray label barcode. *Scan the barcodes: The barcode scanner detects the USPS tray label barcode by detecting a trigger, indicating successful scanning by emitting a beep or vibration. *Verify the scanned information: Verify the barcode matches the tray label's information, including USPS facility ID, tray type, and tray number, after scanning. *Repeat the process: Repeat scanning process for each mail tray, ensuring the correct barcode is scanned for each tray.
