Prevent the subscription outage when a credit card expires.
Credit cards typically expire after about five years. When the replacement arrives, every service charged to that card needs the new number, expiry, and security code. The more subscriptions and utility bills sit on a single card, the more an expiry behaves like a silent outage — multiple services failing on the same day.
Know what each card is paying for
A primary household card is usually paying for far more than it feels like — video and music subscriptions, cloud storage, telecom, utilities, donation services, one-click checkout on ecommerce sites. Trying to remember the full list a week before expiry is unrealistic.
Snap a photo of the card in Kigen, save its expiry, and link the services it pays for as a single bundle.
Pull up the list sixty days before expiry
Replacement cards usually arrive a month before expiry. Waiting until then to remember every linked service is too late — outages start surfacing. Kigen pings you sixty days out and opens the linked-services list in one tap.
- 60 days: review linked services
- 30 days: confirm replacement card arrival
- On arrival: re-register the list top-to-bottom
- Mark each as done to clear them off the list
Manage supplementary cards separately
The primary cardholder and any supplementary cards have different numbers and security codes, so re-registration is per card. Kigen lets you keep each card as its own entry, so partner A's services don't get mixed with partner B's.
We recommend not storing the full number
Kigen is not designed to be a vault for card numbers and security codes. The expiry date and the last four digits are enough to know which card a service is registered to, and these stay safer than full numbers in a synced app.
Treat replacement day as a re-registration event
Block off half an hour the day the replacement arrives. A focused thirty-minute window beats letting it dribble across two weeks and missing one. Kigen's checklist exists for exactly that block of time.
