Chicago Sun Times copy editor Josie Gellar (25), who was desperate to graduate from perfectionist copy editor to reporter, gets her chance when the goody owner orders the editor to cover the high-school scene by undercover. Josie, who was a frustrated, ridiculed nerd, gets a popular make-over from her drop-out, naturally funny brother Rob Geller. Both siblings find love and joys of youth again. But in Josie's case, it's sensitive bachelor teacher Sam Coulson, who enjoys sophisticated conversation. As the publication deadline approaches, the price of blowing their cover seems ever more daunting, yet inevitable unless she sacrifices her career. Written by KGF Vissers
APDU commands are always sets of pairs. Each pair contains a command APDU, which specifies a command, and a response APDU, which sends back the execution result of the command. In the card world, smart cards are reactive communicators -- that is, they never initiate communications, they only respond to APDUs from the outside world. The terminal application sends a command APDU through the CAD. The JCRE receives the command, and either selects a new applet or passes the command to the currently selected applet. The currently selected applet processes the command and returns a response APDU to the terminal application. Command APDUs and response APDUs are exchanged alternately between a card and a CAD.
