According to BBC NEWS…

Monopoly money will be phased out in a new version of the game in a bid to keep up with the times.

Instead players will use mock Visa debit cards to keep track of how much money they are winning or losing.

An electronic machine is provided, which allows the banker to transfer money from players and record their earnings and payments.

But…

The new updated edition of the game is being sold along with the traditional cash version.

Phew!
