Banking includes commercial, investment, retail banks, cooperative banks and credit unions. Card networks include Mastercard, Visa, American Express, Discover and other smaller players. They handle the processing of credit, debit and prepaid card transactions and partner with merchants to facilitate the use of these cards, acting as a gateway between card issuers, merchants and card holders. They create the virtual infrastructure and also set the terms for all transactions (e.g., fees, fraud liability, purchase protections). Insurance includes property and casualty, life and mutual insurance. Other financial services include personal and business credit institutions, mortgage lending, tax preparation, hedge funds, private equity, venture capital firms, wealth management, payment platforms, companies engaged in the underwriting, purchase, sale or brokerage of securities and other financial contracts; also includes fintech companies that have disrupted the industry and leverage the internet, mobile devices, software technology or cloud services to provide traditional financial services (e.g., banking, insurance, lending) and emerging financial services (e.g., payments, crowdfunding, cryptocurrency, blockchain, etc.)
