The prerequisites for cashing a check are the same whether you are cashing it for an exact amount or a flexible amount.

- You need the ID of a Check object currently in the ledger.
    - For example, the ID of one Check in these examples is `838766BA2B995C00744175F69A1B11E32C3DBC40E64801A4056FCBD657F57334`, although you must use a different ID to go through these steps yourself.
- The **address** and **secret key** of the Check's stated recipient. The address must match the `Destination` address in the Check object.
- If the Check is for a [token](tokens.html), you (the recipient) must have a [trust line](trust-lines-and-issuing.html) to the issuer. Your limit on that trust line must be high enough to hold your previous balance plus the amount you would receive.
- A [secure way to sign transactions](secure-signing.html).
- A [client library](client-libraries.html) that can connect to the XRP Ledger, or [any HTTP or WebSocket client](get-started-using-http-websocket-apis.html).
