At the present days, Vending Machines are well known among Japan, Malaysia and Singapore. The
quantity of machines in these countries is on the top worldwide. This is due to the modern lifestyles which require fast
food processing with high quality. This paper describes the designing of multi select machine using Finite State Machine
Model with Auto-Billing Features. Finite State Machine (FSM) modeling is the most crucial part in developing proposed
model as this reduces the hardware. In this paper the process of four state (user Selection, Waiting for money
insertion, product delivery and servicing) has been modeled using MEALY Machine Model. The proposed model
is tested using Spartan three development board and its performance is compared with CMOS based machine.

All the authors, conference coordinators, conveners, and guest editors kindly check their articles' originality before submitting them to IJCERT. If any material is found to be duplicate submission or sent to other journals when the content is in the process with IJCERT, fabricated data, cut and paste (plagiarized), at any stage of processing of material, IJCERT is bound to take the following actions.
1. Rejection of the article.
2. The author will be blocked for future communication with IJCERT if duplicate articles are submitted.
3. A letter regarding this will be posted to the Principal/Director of the Institution where the study was conducted.
4. A List of blacklisted authors will be shared among the Chief Editors of other prestigious Journals
We have been screening articles for plagiarism with a world-renowned tool: Turnitin However, it is only rejected if found plagiarized. This more stern action is being taken because of the illegal behavior of a handful of authors who have been involved in ethical misconduct. The Screening and making a decision on such articles costs colossal time and resources for the journal. It directly delays the process of genuine materials.
