What trends do you think will really change how we pay for things soon?

Some people say cash is king and will never truly disappear, but others believe digital payments will soon dominate every transaction. I'm always curious about the next big thing in how we handle money. What innovations do you foresee making the biggest impact on our daily transactions, both online and in physical stores, in the coming years? I'm particularly interested in things that are already starting to show up and might become mainstream soon.
