Wise debit card tips for travelling developers

The Wise debit card is one of the most-used cards in the nomad and remote-worker stack. The way it works in practice is more nuanced than the marketing suggests. ## How spending works The card spends from the matching currency wallet first. If you have a EUR balance and spend EUR, no FX. If you have only USD and spend EUR, Wise converts at mid-market with a small fee (0.4 to 0.7 percent typical). ## What does not have FX Spend in currencies you already hold balance for. ATM withdrawals up to a monthly free limit in any currency (currently around 200 EUR equivalent per month, then small per-withdrawal fee). ## What does have FX Spending from a currency you do not hold (auto-converts at the time). Online purchases in a third currency from a vendor in a fourth currency. Hotel pre-authorisations that hold from your default currency. ## The pattern that works Hold a small float in the local currency wherever you spend. Top up monthly from your main currency. Use ATM only sparingly; card spend has cleaner accounting. ## Surprises to know - ATM fees: free until ~200 EUR per month, then small per-transaction fee - Some merchants do dynamic currency conversion (DCC); always decline DCC and spend in local currency - Pre-authorisation holds can last 7-14 days; Wise releases the hold when the merchant clears ## Lost or compromised card Freeze instantly in the app. Order a replacement to your shipping address. Virtual card is available immediately while you wait. ## Tax angle Card spend is just spending; no income tax implication. But every spend in a foreign currency converts at the day rate. For tax reporting in your home country, the running statement helps.
