    The Electronic Cash Register (ECR) keeps track of sales transactions quickly and effectively. An abundance of PLUs (Price Look Ups) and department keys accommodate a variety of merchandise items. This means a faster, more accurate check out process and the ability to manage a wider variety of goods and services more efficiently. And with features like fast, attractive receipt print outs and an easy-to-view LCD operator display, the ECR makes managing the business a pleasure.
    The system runs on the full speed provided by the microcontroller. It runs at the speed of 24MHz. so the sales Transactions are done very fast and the system only take 3secs to search the Bill from the 512KB Memory IC, the printing also done very fast by using the microcontroller. The features of the project is given below
    * Fast & Neat Billing with Accuracy
    * Easy to use keyboard/alpha numeric backlit display.
    * Extensive daily report.
    * Day/date/year & precise time with AM/PM.
    * Full inventory control.
    * Single key Last bill printing
    * User programmable Greeting messages.
    * Password protection.
    * 4-line 20 characters per line backlit LCD.
    * Large LED customer display
    * PC keyboard.
    * 999 price look-ups (PLU) for programming automatic price entry
    * 10 BPM (Bills Per Minute)

    Use RIDE for assembling and not KEIL or some other.
    Else you can directly use the HEX file.
