Safe Digital Payments Worksheet

Money maths lesson 27: Safe digital payments · Set 22 · 40 sums

The method (Stop, check, ask): Never share an OTP or PIN with anyone — not on a call, message or link, even if they say they are from a bank. A PIN or scanning a QR code is only for paying; you never need it to receive money. Before paying, check the name and the amount. Prize links and “you have won” messages are tricks — ignore them and tell a parent. Paid by mistake or something looks wrong? Tell a grown-up at once.
