I was travelling from Camden Town to Old Street and on the way out instead of touching my oyster card I used my dad's oyster which is 60+ I was stopped by Revenue Control Inspector. Of course, I apologised and explained that I made a mistake. He asked me couple questions, I gave him my driving licence so he wrote down all details and he said that I will receive a letter in the post. I haven't received any other letter apart from the Single Justice Procedure Notice.
I am more than happy to pay the fine as it was my mistake for not using my oyster card. But my biggest concern is the criminal record. This is happening to me for the first time. Do you think I can contact TFL and ask for out of court settlement? I have 21 days to plead either Guilty or Not Guilty to the offence.
There ought to be no criminal record associated with a Byelaws conviction. Frankly, unless you didn't realise you were using your dad's Freedom Pass, I would jump at being offered the chance to be convicted "only" for a Byelaws offence. It wouldn't be all that difficult to prosecute an offence under Section 5(3)(a) of the Regulation of Railways Act 1889 (RoRA) - which would indeed carry a criminal record and would be a crime of dishonesty potentially barring you from getting visa-free entry (or entry at all) into certain countries.
You can try contacting TfL to settle the matter, but you will want to be
very careful not to admit to a more serious offence (RoRA) than that for which you are being prosecuted. Furthermore, TfL are generally more likely either to drop a matter, or prosecute it - in a similar way to the police or the CPS. Out of Court settlements are possible, but much less common than with the privatised operators (which are generally amenable to settlements, as it means they get more money and incur fewer costs).
Whatever you do,
don't miss the 21 day deadline, even if you're still waiting for a response from TfL. And to be quite honest, unless there are some extenuating circumstances we're not aware of, I don't think there is any grounds for you to plead 'not guilty'.
