A single mention of Bitcoin in a piece about the Commonwealth Bank's 'Kaching' banking application
Cashing in on Kaching
This is also presumably why CommBank is calling Kaching-to-Kaching payments "peer-to-peer" when they're nothing of the sort.
These payments still involve a central entity, the bank, just like any other bank transfer. True peer-to-peer transactions would see the funds go directly from payer to payee without involving anyone else.
Offline that's done with cash. Online that's only possible with emerging systems such as BitCoin or perhaps Canada's MintChip digital cash.
