Paper tickets are an absolute pain - I hate having to fumble around trying to find them, instead of just double clicking the power button and bringing up my Wallet.

I've only ever had it checked by the barriers, I can't remember the last time I saw a conductor checking tickets on a train.

Some stations don't have barriers, which seems to correlate with tickets being checked on those routes more frequently.

(e.g. York, or Edinburgh.)
