Most people in the country use Econet Wireless, Zimbabwe's Ecocash mobile phone payment system for daily transactions. They buy electricity in units of $5 or less and almost all domestic users are on pre-paid meters, so many buy for $1 at a time.
According to Zimbabwe's finance ministry less than 5% of commercial transactions in the country involve cash, mainly because it's hard to find. Instead, Zimbabweans use Ecocash or bank cards.

Econet, Zimbabwe's biggest mobile phone company, declined to comment.
