Peer Reviewed & Fact Checked

1. The Attack

A criminal places their own payment code over the shop's, so payments flow to their account. Customers and owners may not notice until money is missing.

2. Merchant Controls

* Mount the code in a fixed holder or behind clear acrylic with the shop name. * Check it every opening and closing. * Enable payment notifications and reconcile them with sales. * Use a code displaying your business name.

3. Customer Habit

Customers should confirm the payee name shown in their banking app matches the shop before approving.

4. Staff Training

Teach staff how the genuine code looks and to report any change immediately.
