We can offer following types of RFID tags and cards.

Passive RFID-tags are working without internal power supply. Induced power into coil antenna of tag is enough for embedded CMOS chip power supply and data transmission back to reader. Such microchip can be implemented into any type of casing as for example into plastic card or any shape tag for working with ERP systems..
Most widely used standarts for such devices are:
• Em-marine
• HID
• Mifare
• I-Code.
RFID technology allows to manufacture tags very tiny: for commercial needs used RFID-tags can be implemented as barcode sticker or even embedded under the skin.
