Abstract
A method for preventing misappropriation of plastic money includes transmitting a first verification data from plastic money to an accompanied card through a wireless signal; comparing the first verification data with a second verification data stored in the accompanied card; if the comparison result is that the first verification data is identical to the second verification data, transmitting a verification success message from the accompanied card to the plastic money through the wireless signal; transmitting a first short message or E-mail including intended payment information from the plastic money to a cell phone number or an E-mail address of a cardholder of the plastic money through the wireless signal to inquire whether the cardholder of the plastic money agrees to pay or not; clicking a particular hyperlink in the first E-mail with a mobile device or pressing a particular button or icon of the mobile device by the cardholder of the plastic money to agree to pay and transmitting an approved payment message back to the plastic money through the wireless signal.
