Question 1

Why is the rate different from the one on Google?

Accepted Answer

Google shows the mid-market rate, which moves every few seconds and isn't available to consumers. Lumi's rate is live, close to it, and fixed once you see the confirmation screen.

Question 2

Is Lumi cheaper than my bank card?

Accepted Answer

Usually, yes. European banks often charge 1.5–3% per foreign card payment plus a 2–5% exchange margin, and ATMs add withdrawal fees. On €1,000 of spending, Lumi costs about €20 in fees, versus €60–144 with cards, ATMs or airport exchange.

Question 3

Will my bank charge me for using Lumi abroad?

Accepted Answer

SEPA transfers in euros within Europe are generally free of transfer fees. However, fees may depend on your bank and account type, so check with your bank if you're unsure.

Question 4

Does the merchant pay a fee?

Accepted Answer

The merchant receives the full amount in local currency, just as if a local had paid.

Question 5

Does the exchange rate change between scanning and paying?

Accepted Answer

The rate is shown on the confirmation screen and applies when you confirm. If you leave the screen open for a long time, it may refresh to the latest rate.

Question 6

Should I pay in euros or local currency if a shop offers both?

Accepted Answer

With Lumi you always pay in local currency and the conversion is done by Lumi, so this choice doesn't come up. On card terminals, always choose local currency; paying in euros there usually costs more.
