Contactless payments: what a tap does
A card or NFC device exchanges information with a compatible terminal without being inserted into a reader.
A tap does not set the tariff
FinFly’s takeaway: the communication method does not specify your bank’s fees, conversion rate or limits. Check those separately.
An unclear terminal response
FinFly recommends checking the transaction status and receipt before paying again. A device sound does not replace checking the amount and outcome.
