# Update a Reader

`PATCH /v0.1/merchants/{merchant_code}/readers/{id}`

Update a Reader.

## Path parameters

- `merchant_code` string, required
- `id` string, required — Unique identifier of the object. Note that this identifies the instance of the physical devices pairing with your SumUp account. If you DELETE a reader, and pair the device again, the ID will be different. Do not use this ID to refer to a physical device.

## Request body

- object
  - `name` string — Custom human-readable, user-defined name for easier identification of the reader.
  - `meta` Meta — A set of key-value pairs that you can attach to an object. This can be useful for storing additional information about the object in a structured format. **Warning**: Updating Meta will overwrite the existing data. Make sure to always include the complete JSON object.

## Response `200`

- Reader — A physical card reader device that can accept in-person payments.
  - `id` string, required — Unique identifier of the object. Note that this identifies the instance of the physical devices pairing with your SumUp account. If you DELETE a reader, and pair the device again, the ID will be different. Do not use this ID to refer to a physical device.
