The DSECASH eCash Evaluation Kit demonstrates the speed, reliability, and security of a SHA-1 based, iButton® eCash system. The eCash debit board provided in the kit is a complete stand-alone module that will perform monetary debits in a fast 100ms. The debit board also has a serial interface that allows a PC or microprocessor to monitor the debit process. Utilizing the serial interface, the demo board could easily be integrated into a real eCash or access-control system. For a more detailed look at the DSECASH kit, please see its data sheet: DSECASH
The DSECASH starter kit includes several parts, as noted below. If other parts are needed for further evaluation and testing purposes, they can be purchased from our online store.
DSECASH Kit Contents
There are setup requirements before getting started with the DSECASH kit:
The primary purpose of the eCash Evaluation Kit is to demonstrate SHA-1 iButton devices by showing a fully qualified, SHA-1 authenticated, monetary debit in ~100ms using the file and security standards described in other Maxim Application Notes (See White Paper 1 in table below). Targeted applications include: vending, parking meters, toll booths, pay phones, public transportation, gaming, and other applications requiring either secure payment or user authentication. The following iButton and 1-Wire Application Notes discuss SHA-1 topics. (Users are recommended to start with White Paper 8, 1-Wire SHA-1 Overview.)
Before stepping through the "Quick Start" section below, users are advised to perform the following tasks:
