Methods and systems for detecting lateral intrusion of a secure electronic component enclosure are disclosed. According to one system, the system includes a secure enclosure for enclosing at least one electronic component. The secure enclosure includes a first and a second printed circuit board (PCB) and a security ring sandwiched between the first and second PCBs defining an interior region for enclosing the at least one electronic component. The PCBs define opposite sides of the enclosure and the security ring defines lateral surfaces of the enclosure. The lateral surfaces defined by the security ring are wrapped by at least two wires that define at least two circuits. An intrusion detection module detects an intrusion of the secure enclosure based on a condition of the at least two circuits.

A paystation device adapted to be coupled to a transaction terminal for carrying out a transaction between a seller and a buyer using a smart card having a cash token value stored therein and having a current cash token value. A smart card interface accepts insertion of a smart card for reading a current cash token value stored therein and for writing a new cash token value thereto. A display device displays cash amounts. A communication interface communicates data messages between the paystation device and the transaction terminal. A programmed control unit is coupled to and operates the smart card interface, the display device, and the communication interface.
