Can't load a Network SouthEast card, hence the exception.

Whyever not?

Perhaps it's because the Network Card £13.00 minimum weekday fare, and the
'after 1000' rule mean it isn't any use for 5 days out of 7...

The Network Card also has group and children validity, but its use by an
individual should be programmable for weekend use only.

Also, a NSE card if loaded on Oyster can't then be read by NSE ticket
offices outside the zonal area. To provide both a paper & Oyster NSE
discount card would leave it open to fraud, with both usable
simultaneously by different people....there's no photocard needed!
