Grade: Date: 25/02/2026
Subject: Information Communication Technology ICT
Lesson Topic: Know and understand electronic funds transfer at point of sale (EFTPOS) terminals including checking of the validity of cards, the use of chip and PIN, the use of contactless cards, the use of Near Field Communication (NFC) payment, the communication
Learning Objective/s:
  • Describe the components and flow of an EFTPOS transaction.
  • Explain how card validity is verified and why the checks are essential.
  • Demonstrate the chip‑and‑PIN process and the security it provides.
  • Compare contactless and NFC payment methods, highlighting limits and tokenisation.
  • Analyse the ISO 8583 message structure and identify key security controls.
Materials Needed:
  • Projector and screen
  • Whiteboard and markers
  • EFTPOS terminal demo unit
  • Sample cards (magstripe, chip, contactless)
  • Laptop with slide deck showing network diagram
  • Handout summarising ISO 8583 fields
  • Worksheet for group activity
  • QR code‑linked mobile wallet demo (e.g., Apple Pay)
 Introduction:

Begin with a quick poll: “How many of you have paid with a card or phone today?” Connect this to prior knowledge of cash transactions and set the success criteria – students will be able to trace a payment from card to bank and explain the security steps involved.
Lesson Structure:
  1. Do‑now (5’) – short quiz on different payment methods to activate prior knowledge.
  2. Mini‑lecture (10’) – overview of EFTPOS components and card‑validity checks (physical, Luhn, expiry, status).
  3. Live demo (15’) – demonstrate chip‑and‑PIN on the terminal; students observe each security step.
  4. Guided practice (10’) – students pair up to simulate contactless tap and NFC phone payment, noting limits and tokenisation.
  5. Group analysis (10’) – decode a sample ISO 8583 authorisation request, identify key fields and security measures.
  6. Check for understanding (5’) – exit‑ticket question: “What is the most critical security feature of chip‑and‑PIN vs. contactless?”
Conclusion:

Recap the main steps of an EFTPOS transaction and the differences between chip‑and‑PIN, contactless, and NFC payments. Collect the exit tickets and assign a brief homework: research one emerging payment technology (e.g., biometric cards or QR‑code payments) and prepare a one‑minute summary for the next class.
