Methods Used to Hack Kopitiam Stored Value Cards

The Kopitiam stored value cards were compromised through a system that facilitated illegal top-ups. This hacking operation involved the modification of the stored value cards themselves, utilising a specific application and a phone's Near Field Communication (NFC) scanner. Two Samsung S3 mobile phones, equipped with NFC capabilities, were central to this process, enabling the illicit enrichment of the card balances.
Modification of Stored Value Cards

The core of the hacking method involved altering the stored value cards to enable unauthorised credit. This process was initiated by an individual named Teoh, who possessed the knowledge to illegally top up the cards. Teoh would modify the cards for a co-accused, demonstrating a technique that bypassed legitimate payment channels.
Utilisation of NFC Technology and an App

The illegal top-ups were executed using an application in conjunction with the Near Field Communication (NFC) scanner present in mobile phones. Specifically, two Samsung S3 mobile phones were acquired for this purpose. This technology allowed for the manipulation of the card's stored value by interacting with its internal chip.
System Acquisition for Widespread Hacking

Beyond individual card modifications, a system was purchased to facilitate broader hacking efforts. This system, which included the necessary app and NFC-equipped phones, was bought for S$500. The intention behind acquiring this system was to enable the modification of multiple stored value cards, thereby expanding the scope of the fraudulent activity.
