STRENGTHS WEAKNESSES
inter-scheme and scheme to/from Bank integration simplified Very low value transactions are not currently routed through acH –
unknown impact
inter-scheme settlement through central bank reserve accounts
partner bank required for settlement – may introduce additional costs
Direct connection may be required by the central bank as the volume of inter-
scheme transfers grows over time user experience for sending money from bank account to mobile wallet
account is undefined
unknown ability of acH to handle additional transaction volumes
acH may not be real time – settlement delay associated with intra-day
settlement through the acH
a banking sector acH is typically not designed to refer to accounts using the
mobile phone number
acH rule book not designed to allow for mix of ‘real’ money and e-money
control resides with the members of the acH, not mmo schemes
Table 5: Direct Connectivity to National ACH Strengths and Weaknesses
From a technical architecture point of view, this approach appears to be the simplest – a single interface to an existing service. However,
the rules and interfaces for a banking sector acH are not designed to allow for e-money to be cleared. changes to allow this would
require agreement with the banking sector and the central bank.
