No, actually the camera is not used at all.
But I'm thinking about an external app to take picture of a sheet of barcodes and transform them in a config '.wnd' file.
Btw the format of this file is quite easy 5 lines per barcode, 50 barcodes per file.
line 1: text displayed on the key
line 2: idx of barcode, not meaningful in the file (used internally), put here 65536 to be safe
line 3: type of barcode, also not meaningful, just put the real type of the code (0 to 9) or 4
line 4: len of the barcode in byte, it is used, so put the right value
line 5: xxyyxxyyxxyyxxyyxxyyxxyyxxyyxxyy 16 bytes in hex digits, right padded with 00
That's all, so it's easy to make such a file. But be careful, the checksum byte (or nibble) should be ok, otherwise the 41 will complain.

P.S. btw the nexus 7 tablet doesn't have a rear facing camera, so it is not possible on all tablet to include such a feature
