How to Replace a Lost Card

When a child’s KiddyCash payment card goes missing — whether left behind after school in Nairobi, dropped at a market, or simply misplaced — the priority is to deactivate the old card immediately and issue a replacement. This guide walks you through the nuances of that process: what signals a card is truly gone, why a simple freeze isn’t always enough, and how to complete the replacement cleanly.

Symptoms

You likely need a replacement (not just a temporary freeze) if:

  • The card has been missing for more than 48 hours with no sign of recovery
  • Your child reports it was lost in a public place or on transit
  • You’ve noticed unauthorised or unexpected transactions on the card
  • The physical card is damaged beyond use (e.g., chip unreadable, card snapped)
  • A previous freeze hasn’t resolved the underlying concern and you want the card permanently retired

Causes

Lost card situations in KiddyCash typically fall into a few patterns:

  • Physical loss — the most common case. Cards left at school canteens, on matatus, or during shopping trips.
  • Theft — less frequent, but requires faster action since the card may already be in use.
  • Damage — hardware failure or wear that makes the card non-functional even if technically “found.”
  • Security concern — a parent may want to replace a card after a child shared their PIN or after a suspicious transaction, even if the card is in hand. In this case, replacement resets the card identity entirely, which a freeze cannot do.

Note: If you’re unsure whether the card is truly lost or just temporarily misplaced, consider a temporary freeze first. Replacement is irreversible — the old card cannot be reactivated once a replacement is issued.

Solution

Step 1 — Confirm the old card’s status

Navigate directly to your child’s payment card screen. You can access it at:

https://kiddy.cash/family/kiddy/account/payment-card/:payment_card_id

Replace :payment_card_id with the specific card ID shown in your app. For a refresher on locating card details, see how to view a child payment card.

Step 2 — Freeze the card immediately

Before issuing a replacement, freeze the card to prevent any transactions — including M-Pesa-linked spend or in-store purchases — while you complete the process. The freeze takes effect instantly.

Step 3 — Initiate replacement

From the card detail screen:

  1. Tap Manage Card
  2. Select Replace Card
  3. Confirm the reason (Lost, Stolen, or Damaged)
  4. Review the replacement fee if applicable (this varies by your subscription tier and may be waived for first replacements)
  5. Confirm issuance

The old card is permanently deactivated at this point. Any recurring transactions or auto-debit rules tied to the old card will need to be reviewed — they do not automatically transfer to the new card.

Step 4 — Set up the new card

Once issued, the replacement card follows the same setup flow as a first-time card. If you need a refresher on configuration options — spending limits, PIN setup, merchant restrictions — refer to how to issue a payment card for a child.

Note that the new card will have a different card number. Update any linked school payment systems or subscription services that reference the old card details.

Step 5 — Notify your child

Use the in-app messaging or your own channel to let your child know the old card is inactive. If they’re old enough to manage their own spend in KES, walk them through activating the new card so they’re not caught short.
