Handheld computers with barcode and/or RFID readers can be offered for applications like Inventory management, Asset Inspection, Maintenance Management, Items Picking and Dispatch etc. These computers get the Enterprise data from the ERP systems or legacy systems through the WiFi or 2G/3G/4G interface and present them to the user. Field user can scan the items using barcode / RFID reader. These devices update the data to the server in real time. If the server connectivity is not available, data will be stored and synchronized later.
