title: Call different applet in javacard
body: <p>I have 2 applets in java card. The <a href="https://github.com/JavaCardOS/LoyaltyCardApplet/blob/master/src/LoyaltyCardApplet/LoyaltyCardApplet.java" rel="nofollow noreferrer">first applet</a> functions as a loyalty card. <a href="https://github.com/philipWendland/IsoApplet/tree/master/src/net/pwendland/javacard/pki/isoapplet" rel="nofollow noreferrer">The second applet</a> functions to store transactions.</p>
  <p>I want to log the <code>add balances/credit transaction</code> and <code>purchase transactions</code> to <code>eeprom</code>  using the second applet.</p>
  <pre><code>file_name: month
  -----------------------------------
  datetime | transaction code | amount
  -----------------------------------
  
  month:
  01 = january
  02 = february
  ect..
  
  datetime (7 bytes): 
  dd MM yyyy HH mm ss  
  
  transaction code (1 byte):
  01 = purchase
  02 = add balance
  
  amount (4 bytes):
  FF FF FF FF
