If people are still using barter, that's fine, they don't need money.

If they do need money, I'm suggesting e-cash could be converted into PHYSICAL CASH. I don't know how to be more clear, you don't seem to be reading my words. PHYSICAL CASH. PAPER BILLS. I'm not suggesting an African grandmother needs to buy a smartphone. You're the one implying that e-cash isn't worth developing because you need a smartphone to use it. I'm the one arguing you might not need a smartphone to use it.
