3. Current Receipt System
Given a paper receipt after every purchase
Receipt can be very long even if you buy one item
Hassle to keep track of
Waste of paper and ink

4. How significant is the Problem?
Environmental cost per year
250,000,000 gallons of oil
10,000,000 trees
1,000,000,000 gal. of water
1,500,000,000 lbs of waste
Receipts can cost ~1c per print
* According to study done by Clinton Global Initiative University (2013)

5. Our Solution: Digiceipt
A system which automatically generates and transfers your receipts through an NFC transceiver at a point-of-sale to a mobile application
One which easily keeps track of digital receipts for storage and retrieval in a cloud database

6. Design Alternatives Data Transfer Alternatives Platform Alternatives
Bluetooth QR Code

NFC Transceiver
-Transmits wireless data

11. Inputs Takes in purchase data from Point of Sale with barcode scanner
Scanner will be compatible through USB connection
Sends data to the computer to be transmitted via NFC transceiver

12. Computer (Raspberry Pi)
Raspberry Pi computer with 3 interfaces
Interface to receive data from the scanner
Interface to communicate with NFC transceiver
Interface to communicate with display monitor

13. Near Field Communication (NFC) Transceiver
Transmits and receives data
Syncs only to android App
Displays items being purchased
Utilizes Raspberry Pi

14. Android App Interface connecting consumer and receipts
Must sync with NFC transceiver at point of sale to transfer data
Enables permanent, secure receipt data storage in a cloud database
Must be fast and easy to use

15. Proposed MDR Deliverables
Scanner interfaces with Raspberry Pi in a way that raw data is transmitted
Raspberry Pi is able to transmit the raw data to NFC transceiver
Transceiver can communicate with Android app and sends raw data via NFC
Android app receives raw data and displays it
