When using a Bluetooth barcode scanner with an iPad, iOS uses the scanner as the main input device. This can create a very annoying issue as iOS disables the built-in virtual keyboard. This essentially means that any time you want to manually type any information you have to uncouple the Bluetooth scanner to gain access to the on-screen keyboard again. This issue is caused by iOS's need for certified devices.
The Solution:
Purchase a barcode scanner that is iOS compatible, Socket have barcode scanners capable of acting as a HID Bluetooth device which retains the virtual keyboard functionality by double tapping the power button to allow simultaneous scanning and keystrokes.
