A low-power smart card reader that plugs into the circuit board of a base-model electronic meter is provided. The smart card reader includes positive contacts for reading the card chip and a circuit board to step-up the voltage, pass through the commands, and provide a CPU clock. The smart card reader circuit board includes sockets for its own plug-in microprocessor and multiple SAM modules. A development system couplable to a computer system for developing security schemes such that vending machines can accept smart cards is provided. The development system further includes a reader and at least one socket operable to receive a security access module. The reader is operative to read smart cards. At least one socket is in communication with a processor operative to determine which of the sockets includes the security access module adapted to communicate with the security scheme of the card read by the reader.
