Re: SMS Banking

[Doug Farre <dougfarre () gmail com>]

Mobile phone numbers can be spoofed. My piece of advice is that all
transactions must be acknowledged by the user. For instance, user
makes a request, system asks the user if for confirmation, then the
system proceeds.

Also, keep in mind that a lost cell phone can mean the user's pin is
compromised as the sms msgs are all stored in plain text.
