ATR: T=1, FI=1/DI=8 (31clk/etu), N=0, IFSC=254, BWI=4/CWI=5, Hist="JCOP41V223"Now you could set ATR after perso the card.
Make sure install the applet as default applet. Application: SELECTABLE (-----D--) A00000000002

Good post, sonnyyu. I would a comment though: Visa OpenPlatform is proprietary to Visa. It is better to use the GlobalPlatform standard.
import org.globalplatform.*;
GPSystem.setATRHistBytes(newATRHistory, (short)0, (byte) newATRHistory.length);
..
