A method, programmed medium and system are provided for using a payment card with an embedded RFID device. In one example, a cellular telephone or other wireless device is used to generate a one-time password (OTP), which is then transmitted by a read-write RFID in the wireless device to the read-write RFID which is embedded within a payment card. The user's phone or other wireless device then activates the writing of the OTP to the RFID of the payment card. The payment card, with the one time password now saved in the card, is then handed to the waiter or store clerk for payment approval and/or further processing. The user's OTP is then read by the merchant's RFID reader and transmitted to an approving agency/server for approval or disapproval of the user's purchase.
