KidZania has it’s own economy, ‘KidZos’ is the legal currency.
Each time you visit KidZania, you will receive a 50 kidZos check. Once inside, you must go to the bank, cash your check and use your money to buy goods and services such as: riding a taxi, get a hair-do at the Beauty Salon, or shop at KidZania's Department Store.

KidZos are not for sale with real money, if you want to spend all your kidZos or to earn more, you must get a job and work to provide a product or service such as: firefighter, dentist, hairdresser, donut maker, or choose among many different professions.

At every establishment or activity you may spend or earn kidZos, for example: at the Fire Station you can earn money, while at the KidZania's Department Store you can spend them. However, there are lots of establishments where you can do both of things, at the Hospital, for instance, you can be a doctor and earn money, or be a patient and pay to get medical service.

Consumer goods and product prices are different depending of the establishment or the activity and they can change depending on the popularity of the activity compared with others.

If you want to save kidZos and manage your credit balance, you can open a saving account at the bank.
