This document discusses opportunities in the global remittance market, specifically regarding unbanked immigrant populations. It notes that over $500 billion is sent globally in remittances annually, with the majority going to families in developing countries. Prepaid debit cards linked to mobile phones show promise as a lower-cost remittance solution that could also help connect immigrants and families to the formal banking sector. Such mobile-enabled cards allow instant international money transfers at a fraction of traditional fees and provide a gateway to additional financial services. Facilitating banking access could shift some business from money transfer companies and support greater financial inclusion and economic development.
