Siri and Shortcuts
Ask Siri which card to use
Name a store or category to ask about the cards in your Miles wallet.
| Choose | Action |
|---|---|
| Store | Which card at Costco with Miles |
| Category | Best card for groceries with Miles |
Say the store or category
Sign in to the iPhone app first and add your cards to your wallet. Say “Which card at Costco with Miles” or “Which card should I use with Miles”. The second phrase makes Siri ask which store.
For a category, say “Best card for groceries with Miles” or “Which card for dining with Miles”. The category choices are dining, groceries, gas, travel, and everything else.
Use the actions in Shortcuts
In the Shortcuts app, use Miles’ Which card at a store action for a merchant, or Which card for a category. Siri recognizes suggested stores; if a store is not recognized in the phrase, answer the follow-up question or enter its name in Shortcuts.
The card lookup requires device authentication. If Miles asks you to sign in first, open the app and sign in before trying again.
