# Freeze a Card

> Temporarily block card spend

Temporarily block new authorizations on an **ACTIVE** card. Funding and other operations may still be restricted while frozen.

## How it works

1. **Call freeze** with the target `card_id`.
2. **PayVessel blocks spend**: new merchant charges are declined.
3. **Unfreeze** when the customer should spend again.

## When to use

* Suspected fraud or lost device
* Customer-requested pause
* Compliance hold before investigation
