The 25-year-old has an electronic bank account on her mobile, giving her access to financial services that have traditionally been out of reach for millions of poor in Bangladesh and other developing nations.
From the capital Dhaka, Akhter sends interest earned on her one million taka (USD 12,820) compensation from the disaster quickly and cheaply to her 10-year-old son and parents back in their village.
"Life is tough for anyone who's lost a limb. Nobody gives you a job or cares about your pain," she said of her injuries suffered in the Rana Plaza garment factory complex collapse that killed more than 1,100 people in 2013.

Bangladesh has been the heartland of microfinance thanks to the pioneering efforts of Nobel Prize winner Muhammad Yunus, whose small loans empowered millions of poor.
But the bKash Wallet service has reached further, allowing anyone with a mobile phone to receive wages, send remittances and pay bills for a fee of less than two percent of the transaction.
"bKash has emerged as a very efficient payment arrangement with endless possibilities," its MIT-educated chief executive Kamal Quadir told AFP.
"It's a completely new payment infrastructure, that has access to the country's rich and poor."
Quadir credited its success to its low cost and huge reach -- about 100,000 bKash agents such as shopkeepers are employed in villages throughout the country allowing receivers of electronic money to get their cash.
