Hello, last week I was caught by tfl when they scan my oyster card and I was found I didn't pay and I was so panicked I tell them I pay with my bank card but he didn't believe me I know I'm wrong here because I forgot to tap in cause I was in hurry my train was coming I rush in train without taping in and he ask for my Id and I didn't have my id so he said they will check in cc camera footage that I tap in or not and they will contact my bank about my details and he said I will be fined 1000£ , do tfl ask bank for my details? Other than that they don't have my any identity, I'm having anxiety can't stop thinking about it since it's my first time , I always used to pay to travel but this time was my bad day very bad experience, what could be possibility? do they just send a Letter and just fine me or more than that or may be court summon, sorry for my bad english..
