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.

Re: Smart Card Bitcoin Wallet

Hello,
Can someone help me with the EDCSA signing for Bitcoin?
I took the WalletBitcoin app from here: https://github.com/JavaCardOS/BitcoinWallet
When I try to load it to the card, I get the following error: 0x6438 == Imported package not found.
I am using the following card: 3H145

Thanks
Danny
