Selling games, serial codes, and used software on eBay are easily stolen by hackers. How to transfer them safely and effectively is a very important topic. Such as game items, games that are not played, retail Office and Windows serial numbers on retired old computers can generally be deactivated and sold cheaply. Some software is very expensive, used ones are still valuable.
在eBay上銷售遊戲，軟體授權碼，2手軟體等很容易遭駭客竊取，如何安全有效的傳送是很重要的課題。如遊戲內寶物，不玩的遊戲，淘汰的舊電腦上retail Office, Windows序號若軟體一般可以deactivate 後便宜賣，有些軟體很貴其實2手還是值錢。
