An apparatus and methods securely activate a credit or debit card for a single purchase, a predetermined amount of time, or a predetermined amount of purchases in a predetermined amount of time, while utilizing a portable phone, especially a cell phone, having a card reader. Only transactions using the electronic telephone number and electronic serial number of the cell phone being used, along with preselected information identifying the owner of a swiped card will be authorized to perform credit and debit card transactions, thus providing secured transactions.
