A barcode scanner is the device that captures barcodes on products. It uses a laser or camera to read the pattern of bars and spaces in a barcode, converting it into a digital signal that can be processed by a computer or point-of-sale system. Barcode scanners come in various forms, including handheld devices, fixed-mount scanners, and mobile scanning applications on smartphones.
A microphone is a device that captures sound by converting acoustic energy into electrical signals. These signals can then be processed and recorded for playback or transmission.
The device you are referring to is called a voice recorder or a digital recorder. It captures audio input using a microphone and stores it digitally for playback at a later time. These devices are commonly used for taking notes, recording meetings or interviews, and for dictation purposes.

An electronic device that bypasses damaged portions of the ear and directly stimulates the auditory nerve is called a cochlear implant. This device consists of an external component that captures sound and converts it into digital signals, which are then transmitted to an internal component implanted in the cochlea. The internal device stimulates the auditory nerve, allowing the brain to perceive sound. Cochlear implants are typically used for individuals with severe to profound hearing loss who do not benefit from traditional hearing aids.

A CCD scanner is a charge-coupled device scanner. These scanners are used to scan the barcodes of products in retail stores. It refers to the optical system that makes the scanner work to transfer information to a computer.
The first example that came to mind was a barcode scanner. It's specifically for scanning barcodes.
Supermarkets use lasers for various purposes such as scanning barcodes on products for pricing and inventory management, detecting counterfeit money, and enhancing security systems by monitoring and tracking movement within the store.
Barcode scanners are devices used to Scan barcodes on Products in Big retail Shops.

A barcode reader is considered a direct input device because it captures data directly from a barcode and converts it into a digital format that can be processed by a computer or system. This process occurs in real-time, allowing for immediate data entry without the need for intermediary steps. By scanning barcodes, it eliminates manual data entry errors and enhances efficiency in tracking inventory or processing transactions.
In Information and Communication Technology (ICT), a scanner is a device that converts physical documents, images, or objects into digital format. It captures the content using sensors and translates it into a file that can be processed, stored, or shared on computers. Scanners are commonly used for digitizing paper documents, photos, and barcodes, facilitating easier access and management of information.

there are no barcodes in space only earth has barcodes
Barcodes are to help stores keep control on how much stock they have got

Yes, a phonograph captures sound waves and transforms them into mechanical energy to make recordings. The earliest recording device of this type was invented by Thomas Edison.
