If you're sharing this stuff optically, you'd almost certainly be better off with something like a big QR code. QR can be scanned at angles, has built-in error correction, and (depending on the font you're comparing it against) can probably pack in more bytes. OCR feels more like a hack than anything; you're using a human-readable format with an error-prone medium to communicate non-human-friendly data between two machines!
