SMS banking services are operated using both push and pull messages.
Push messages are those that the bank chooses to send out to a
customers mobile phone, without the customer initiating a request for
the information. Typically push messages could be either Mobile
marketing messages or messages alerting an event which happens in the
customers bank account, such as a large withdrawal of funds from the
ATM or a large payment using the customers credit card, etc
Another type of push message is One-time password (OTPs). OTPs are the
latest tool used by financial and banking service providers in the
fight against cyber fraud. Instead of relying on traditional memorized
passwords, OTPs are requested by consumers each time they want to
perform transactions using the online or mobile banking interface. When
the request is received the password is sent to the consumers phone
via SMS. The password is expired once it has been used or once its
scheduled life-cycle has expired.
Pull messages are those that are initiated by the customer, using a
mobile phone, for obtaining information or performing a transaction in
the bank account. Examples of pull messages for information include an
account balance enquiry, or requests for current information like
currency exchange rates and deposit interest rates, as published and
updated by the bank.
The banks customer is empowered with the capability to select the list
of activities (or alerts) that he/she needs to be informed. This
functionality to choose activities can be done either by integrating to
the internet banking channel or through the banks customer service
call centre.
