Criminal activity does not only cause problems for local communities but also for the country as a whole. The economic impact is huge and crimes like money laundering cost the UK alone billions of pounds every year.
Crime is big business and there are people who are making a lot of money from activities which are illegal. This is why more measures are put in place in order to crack down on this, and financial institutions are required by law to do all they can to prevent money laundering.
One of the ways that an organisation such as a bank will do this is by using AML identity verification like this w2globaldata.com/regulatory-compliance-solutions-and-software/aml-id-checks/ as this is a way to ensure that a person opening a bank account is the person that they say they are.
In order to stop money laundering and the associated illegal activities from going on, police need to be able to gather evidence and trace the money back to the crime.
Of course, the internet is another source that criminals will exploit, as it is easier for them to be anonymous and also a way to communicate with a larger network all around the world, which is what makes cyber security so important. The rise of cryptocurrencies has also been something that has been used by criminals to be able to clean their money from ill-gotten gains.
