Man, just a simple twitter bot that hit me when a transaction was over a certain amount, or perhaps over a certain distance away from home, would be awesome.



This kind of feature is common in most banks that I have seen. Although instead of Twitter, its email and SMS.


Sure, my bank does it too. Finer-grained alerting could be useful, or possibly aggregate tracking ("You've spent more than $50 at Starbucks this month!"). Location awareness would be the most useful fraud prevention tool.


Keep in mind you're only liable for the first $50 in fraud on a credit card. In practice most US institutions will cover 100% of credit or electronic banking losses.

On the flip side, any SAAS that monitored your bank transactions would likely be more interested in developing and selling a profile of you than protecting you.


My idea was that the private,non-SAAS tool could track your total purchases on a particular category (food, gas, restaurants), or even a specific store, and inform you when you are blowing your budget. ("Hey, that latte put you over for the month. Better cut back").
