Our Online Store have the new products: RFID antenna board. Currently it can work with JC10M24R and JCOP4 card chips.
Compared with normal cards, the antenna board module has a smaller size and fixed holes, which is easy to integrate in the IOT(Internet Of Things) project.

Thank you for your kind response! But what about ECC algorithms ? Which key lengths are supported for ECC?
Await for your reply!
