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.

Difference between KeyBuilder and KeyPair

I have doubts about key generation when writing my java card applet. I wonder the difference between KeyBuilder and KeyPair and also the difference between buildKey and KeyPair as well. And what type of memory is used by the genKeyPair() method, Transient or Persistent ? Many thanks for any help.

Get 0X6F00 with KeyPair(KeyPair.ALG_EC_FP,length)

I am stuck in a problem now. When I use KeyPair(KeyPair.ALG_EC_FP,length), it returns status word "0X6F00" ( unknown error ). Does it mean that my card doesn't support ECC? Or anything else?
