Question 1

What is the approximate maximum communication range for an NFC contactless payment transaction at a vending machine?

Accepted Answer

4 centimeters (about 1.5 inches)

Question 2

What does PCI DSS stand for?

Accepted Answer

Payment Card Industry Data Security Standard

Answer

PCI DSS (Payment Card Industry Data Security Standard) is the set of security requirements all merchants — including vending operators — must meet when accepting, transmitting, or storing cardholder data.

Question 3

A customer claims a vending machine charged their card but did not dispense the product. If the customer disputes the charge through their bank, what is this called?

A chargeback occurs when a cardholder disputes a transaction with their issuing bank, which then reverses the charge; vending operators must have proper records to contest invalid chargebacks.

Question 4

Which technology allows a vending machine's cashless payment system to transmit transaction data directly to back-office management software in real time?
