ETHICAL & ENVIRONMENTAL IMPACT ANALYSIS
Team 5 – myATM
Chuan Yean Tan
OVERVIEW
Automated Teller Machine (ATM)
Emphasizes on security
Facial recognition
4-digit PIN
Read/Write cash card via RFID
Touchpad to navigate user menu
Occupancy sensor to detect user
MANUFACTURE Main component to build myATM is wood
Comparatively more environmental friendly to manufacture than other materials such as plastic and aluminum
Solid, durable and long lasting Excessive use of trees will lead to global warning
Developing electronic components Emissions of heavy metals, radioactive elements
into air Use lead-free solder Minimize the area of PCB
NORMAL USE Electricity Wastage
Typical ATM is operating 24/7 Screen are used for commercial purpose rather
than blank screen
myATM utilizes occupancy sensor Occupancy sensor detects user Remains on standby mode when no user is
detected Start up when detect the presence of user
NORMAL USE
RFID emissions Food and Drug Administration (FDA) claims
that low frequency RF emissions can potentially effect pacemakers and other medical device
myATM’s RFID RFID is placed as far away from the userRead range of RFID is very smallStrength of RF emissions are low compared
to a typical RFID
DISPOSAL/RECYCLING Produces electronic waste
PCB can be melted or desolder and retrieve it’s components
Some components can be reused
No hazardous components in myATMDoes not contain batteries except
small amounts of solder
DISPOSAL/RECYCLING Reuse components
Monitor, microcontroller and ATOM board can be refurbish or reused.
Recycle woodWood from myATM can be reusedWood is biodegradable and easy to
dispose
ETHICAL IMPACT
Require a photo taken from userUser might not feel comfortable having a
photo ID
Security has to be strong Facial recognition algorithm must be able
to detect fraudSecurity to prevent hacking
