Common questions
A caller’s name isn’t showing on my phone.+
Open Settings › Caller ID in the app and complete both steps Android asks for: set CardWise as your Caller ID app, and allow it to display over other apps. Android only shows the card for numbers that are not already in your own contacts (those are named by your phone). Caller ID needs Android 10 or newer; on iOS, enable CardWise under Settings › Phone › Call Blocking & Identification.
How do I stop sharing contacts for Caller ID?+
Settings › Caller ID › switch off. To also take back what was already shared, tap “Remove everything I shared” on the same screen.
My number appears in Caller ID but I don’t use CardWise.+
Go to Remove my number, enter your number, and confirm with the code we text you. Removal is permanent. Open →
How do I delete my account?+
See the Account & Data Deletion page for the steps. Deletion is completed within 30 days. Open →
A guest can’t book a slot with me.+
Check your availability in the app: the date must be marked available, within your working hours, and not already booked. Share the link exactly as shown in the app.
Card scanning gives poor results.+
Use good light, fill the frame with the card, and avoid glare. When online, scans go through our text-extraction service for better accuracy; offline, on-device recognition is used instead.
