Card e.g. contactless smartcard made of plastic/paper, used for e.g. access control, has organic semiconductor light emitting component arranged on coil substrate for contactless response to electromagnetic field and connected to coil
摘要
<p>The card has an integrated radio frequency identification (RFID) transponder, and a chip (2) having a memory portion and a flat coil (3) which is arranged on a coil substrate (7). An organic semiconductor light emitting component (1) is arranged on the coil substrate for a contactless response to an electromagnetic field (6) and is connected to the coil. The transponder and the light emitting element are designed as passive components without individual power supply. The chip and light emitting element are communicated with a reader device (5) via electromagnetic field.</p>
