We are looking for someone who can complete the below for our e-commerce website: Payment systemthree types of members: Buyers, Sellers, and
Merchants.Buyer: A consumer who can purchaseSeller: individual who
sells items onlineMerchant: someone who owns an online store1. type of
sale-Seller posts their own product and a buyer purchases the
product.Example: $100 item is sold, Swapen charges 8.75% +$0.15. $8.90
goes to Swapen and the $91.10 cents goes to the seller.2. Type of
sale-Merchant makes a sale to buyer and has to pay Amazon an extra fee.
Aside from the Swapen regular fees.Commission System:A
referral system is where members refer other members to sign up. When a referred members makes a purchase or a sale a commission payment will be paid out on a monthly basis.Resolution center- is a separate
page with a link to the amazon resolution center and a contact
page.Implement a shopping cart for Amazon.
AIM
To introduce to the functional building blocks of an embedded system for developing a real time system application.
OBJECTIVES
i. Introduce to features that build an embedded system.
ii. To help the understanding of the interaction that the various components within an embedded system have with each other.
iii. Techniques of inter facing between processors & peripheral device related to embedded processing.
