Abstract: A prescription medication monitoring system includes a card having a microprocessor and an RFID chip embedded therein. The chip and microprocessor are electrically connected to a text display and multi-digit display on the front surface of the card. The card operates in conjunction with a base terminal located at a participating pharmacy. The base terminal initially uploads a patient's prescription and personal information via a designated server. The terminal also scans the patient's finger to create a fingerprint image, and then records the uploaded information, including the scanned fingerprint image, onto the chip. Pertinent information relating to the prescription, such as medication name, dosage amount, dosage frequency and remaining authorized refills can be readily depicted on the displays.

Abstract: An electronic transaction card such as a gift card includes a card member having a front surface and a rear surface. Sandwiched between the front and rear surfaces is a microprocessor that is activated by a solar cell array positioned on the front surface of the card. The microprocessor is in communication with a multi-digit display and a text message display on the front surface of the card member. Whenever the card member is exposed to ambient light, the recipient's name, a prerecorded message and the remaining available balance of the card as previously recorded on the microprocessor automatically appear on the respective displays.
