I tried out "cell phone minutes" as my alternative currency. I recharged my mobile phone with a credit of US$10. I went to a provision store around my locality. I didn't have money to purchase some food items worth US$5. I negotiated with the seller to give me the goods while I transfer him cell phone credit worth US$5 from my cell phone credit. He accepted and the deal was done. This tells me that it is possible for the World Bank to design an alternative currency financial system to enhance the conventional system.
