An interesting mobile service

I noticed a sign for this mobile service downtown.

This is such a convenient service that I would use it. I've highlighted some elements I found compelling:

"Verrus’ Pay by Cell Phone enables customers to use their credit cards to pay for parking – without using a meter.[...] Customers are able to purchase parking at any time without the need to worry about broken meters or not having enough change. Capital expenditures are reduced through the elimination of investing in meters and the costs associated with them, such as cash retrieval and maintenance.

Features

• Extend Parking Remotely
• 74% of motorists carry cell phones. Offering them the opportunity to park and pay by phone makes carrying change unnecessary.
• Parking expenses can be accessed and printed out online. Clients are also able to logon and see their lot revenues in real time.
• Ability to have parking receipts directly emailed to the client."
