The second class includes options where a payout of cash (or the asset) is made if the barrier is hit (or not hit) during the life of the option and if the option is in-the-money at expiry. These are types of knock-in and knock-out binary barrier options.

This characteristic means that with the same strike, implied volatility and time to expiry one-touch put options will be twice the price of the European binary put option. Why? At the strike one touch put options will be worth 100, while the binary put option will be worth 50.

Intuitively, barrier options should be cheaper than their vanilla counterparts because they risk either not being knocked in or being knocked out. A double knockout option is cheaper than a single knockout option because the double knockout has two trigger prices, either of which could knock the option out of existence. How much cheaper a barrier option is compared to the vanilla option depends on the location of the trigger.
A simple generalization of the asset-or-nothing option is a digital-gap-option.
