A visit to Angkor Mikroheranhvatho Kampuchea (AMK), a microfinance institution based in Phnom Penh, Cambodia. Through its nationwide branch network and army of loan officers (over 500) who sometimes have to travel up to 80km on dirt road by motorbike, AMK provides financial services to over 200,000 rural clients - over half of whom live off under $1 a day - right at their doorstep.
