Scanner app for retail team

I need a simple app, to be able to search and navigate a small database of products with fields sku number, sku name, description, EAN number. Search should be done by text input, or by barcode scanning. Once a product is found and selected, info about the product should be displayed, with the option to show the barcode in full screen. Said operations should be done offline. The product database should be online, and should be edited by an administrator and imported by the application users when told so. The application users will not edit said database, only import it.
