Monitoring for identity theft can be done in a variety of ways, but one of the most popular is using a credit monitoring service. This type of service focuses on finances, making sure to look through your credit file information for certain activity that could indicate identity theft. While it may seem like a complicated thing to use because it does so much for people, this type of identity theft monitoring service is actually quite basic in nature, and more than appropriate to meet the needs of those that use it.
They look for certain activity. Services like this one don't stop thieves and they don't remove them from accounts. They simply go through information and transactions and then report the information that is learned back to users. The activities that they take notice of are ones that have been associated with cases of identity theft in the past... so their presence means there could be criminal activity.
The services are created with the understanding that money is important. People work hard to have the things that they have - they don't want them to be taken or used by others. These services may not be able to outright stop thieves, but they give you back control over your finances and your information, which makes you stronger. Even though they are created by outside companies, there are real people behind them.
There is no obligation. Although after purchasing one of the credit monitoring programs you will have use of the service for as long as you decide to use it. You are free to discontinue use at any time, and on the opposite end of the spectrum, you can keep it for as long as you think it is effective. Situations change, and the companies that create services like this understand that - it's simple to end service, and even simpler to begin it.
