# POS: can't open or close the cash session

> What to do when the POS doesn't respond, and when the issue is Roomdoo's or the physical reader's.

## Two types of POS issues

When "the POS isn't working", the source can be:

* **Roomdoo**: you can't open or close the cash session, the session shows an amount that doesn't add up, yesterday's payments appear in today's session.
* **Reader hardware**: the physical reader doesn't respond, doesn't read cards, won't connect.

Each is resolved by a different team.

## Roomdoo issues (can't open/close session)

**Contact support** with:

* Property name
* What you were trying to do (open the day's session, close it, balance it)
* Screenshot of the error if there's one

We clean the cash session from the back and let you know when you can continue.

## Physical reader issues

If the card reader doesn't respond, it's not a Roomdoo issue. Steps:

1. **Restart the reader** (off and on).
2. **Restart the computer** it's connected to.
3. **Check the cable or bluetooth** between reader and PC.
4. **Try charging a small amount** to confirm.

If after restarting everything it still doesn't respond, contact the **POS provider's technical support** (Redsys, Phone & Sell, etc.).

## When to contact support (Roomdoo)

* You can't open or close the cash session from Roomdoo.
* The cash session shows an amount that doesn't match reality.
* Yesterday's payments appear in today's session.

If you need us to coordinate between Roomdoo and the POS provider, let us know and we'll handle it together.

<Warning>
  Don't force-close the cash session with incorrect amounts to "just close it". The day's balance ends up wrong on record, and at month-end you get mismatches that are hard to track down.
