The transponder is inserted in the vehicle key in the form of a computer chip. Many modern vehicles feature keys that have a keyless entry, where the ignition key sticks out of a large, square case. In that case it is the chip, usually no larger than the tip of a finger, that allows the driver access to the vehicle.
An eBill (electronic bill) is an electronic version of a paper bill that you can view and pay online. Instead of being sent to your home mailbox, eBills are delivered to the websites of companies who you do business with. This could be your bank, credit union, or any company that sends you bills (cable, phone, power, credit card and so on).
eBill accepts payments using a secure, 128 bit SSL encrypted webpage. This is the highest standard in Internet security. All information is stored in a secured database to prevent unauthorized access to the data. All information is kept private, and is not shared.
