RFID Special Cards are from RFID common cards. Because they always have all kinds of sizes, big and small than general ones.
Sometimes, we also call them non-standard cards. And they could be used for access control management, payment, meeting, festivals, etc.
We can also put RFID chip in them as your request, LF, HF, UHF. Then they can be read on different distance.
