3.3.2 Hardware Interfaces
The ecommerce website for Ayesha General Trading Company will interact with only one
hardware component to facilitate its operations. This section describes the logical and
physical characteristics of hardware interface between the software product and these
hardware components.
1. Logical Characteristics:
 Device Types: Barcode scanners

 Interaction Nature: The barcode scanner will interface with the Inventory
Management Module to facilitate the addition, update, and tracking of inventory
items. When an item is scanned, the scanner sends the barcode data to the
software, which then processes it to update the inventory records in the
database.
 Data Flow: The data consists of barcode identifiers, which are sent as input to
the software. The software then retrieves the corresponding product information
from the database and updates the inventory status.
2. Physical Characteristics:
 Connection Type: USB or wireless (Bluetooth/Wi-Fi)

 Special Libraries: Depending on the specific barcode scanner used, libraries
such as ZBAR, ZXING, or other manufacturer-provided SDKs might be used
to handle the barcode scanning functionality.
