Taxi app giant Uber now allows passengers in most parts of the UK to pay in cash.

After trial, cash payment options are expanded to all UK cities this week except London.

However, individual drivers can still exit to accept notes and coins, partly because of their concerns about the safety of carrying them in the vehicle.

The move comes as a major report suggests that in the future, stores and services may need to be forced to accept cash to protect those who rely on it.

On Wednesday, the MP’s finance committee now did not recommend asking for cash approval now, but said its report was a “wake-up call” to the government on the issue.

Uber has become a huge company and dominates the global ride-hailing market and operates in many other transportation sectors. Its rapid rise has sparked controversy and protests from other taxi providers.

Its success is based on new technology, but means customers need cashless payments to use their services.

After pilots in Birmingham, Stock, Nottingham and Leicester, Uber said it has now expanded its cash payment option to other UK cities, as some prefer to pay in cash or not have a bank card.

"We believe that everyone should be exposed to sports, so after successful pilots in some British cities over the past 18 months, we have decided to give passengers outside London the option of traveling cash."

Passengers can choose cash as their payment option on the app. Drivers can choose preferences in their own apps.

If they don't have enough changes, then Uber treats it as a passenger.

The cash option is under review by authorities in London and Uber Eats or booking other forms of shipping is not available through the Uber app.

Cash activist Ron Delnevo's Payment Choice Alliance said Uber's move "proves that they now believe in the future of UK cash" and aligns the company's operations in the UK with many other countries.

He called on the government to introduce a law that would force all stores and services to accept cash.

Ministers said there was no plan to introduce such rules.

However, the latest report from the Finance Committee does highlight a variety of cash-dependent groups, including some people with learning disabilities and those who use cash to keep their budgets.

Among those who rely on cash and provide evidence to the committee are victims of family and financial abuse.

Many people are in danger of tracking down abusers through their payments. For example, buying a train ticket can only be done in cash to avoid abusive partners to realize their actions.

"It's really a matter of life or death," said Sam Smethers, CEO of the charity that survives economic abuse. "Without it, they're monitoring themselves every day, every deal."

Union bank accounts and collateral have also been used as a way to force control over someone, she said.

Cash can be used as the final escape route.

"One victim's living person said she kept the cash from the house in the house until she had enough time to escape from the abuser," she said.

The charity wants to see legally backed cash recognition, but Ms. Smethers said she welcomes the focus of the committee’s report on the plight of those facing financial abuse.
