This paper presents the designation, fabrication and measurement for wireless power transfer (WPT) with high frequency radio frequency identification systems (HF-RFID : 13.56 MHz). Tag antennas are designed as loop antenna with size of ISO card (5.4 cm x 8.6 cm) for two chips that are MF1S5000 and M24LR04. From measured results of power transfer, read range and power transfer range, the prototype tags can be transferred power. They can be read and transferred power at the distance of 4 cm and can be transferred maximum power at 0-3 cm with 3-7 Vdc.
