Different from the conventional black-and-white one- or two-dimensional barcode, the color scale uses assembly of color scales for various colors. Each assembly of multiple color scales represents one element, such that the information capacity is greatly increased. The user can order the ticket via phone or internet. When the user has successfully input the purchase information and complete the payment procedure, the electronic ticket service center can issue and transmit the electronic ticket containing the color scale code to the assigned device through multimedia or wireless transmission. The assigned device can be cellular phones or other mobile communication terminal devices. Upon entrance, the electronic ticket displayed by the cellular phones or the mobile communication terminals is verified by a ticket verification device.
