The card number was permanent, but the CVV and expiration were temporary. Early iterations used "virtual card." Accurate, but it framed the feature as something separate from the real thing and risked making the whole experience feel disposable. I changed the language to "your card" with no modifiers. The temporary elements were labeled specifically rather than qualifying the entire experience as temporary. This builds trust now and avoids a full content rewrite when the display becomes permanent.

Customers who set up recurring subscriptions with temporary credentials would see those transactions decline after the physical card activated. This scenario wasn't in the original scope, but the downstream impact was too significant to ignore. I introduced proactive guidance alerting users to update subscriptions once their physical card arrived.

Legal and compliance required extensive disclosure around what was temporary, what was permanent, where credentials were displayed, and for how long. I designed a bottom sheet that covered everything legal required without cluttering the main card display. The card screen stays clean while the details are a tap away.

The card display was accessible from four places: account summary, account details, card management, and card details. Rather than writing unique copy for each, I created a single reusable message that worked across all entry points.
