Selling in the POS (TCS)

POS login validation (Infrasec requirement)
POS finishes the sale without posting fiscal information
When a POS terminal that is registered for fiscalization starts, it checks whether if it has access to its physical memory device, either the e-Tax Control Unit or Infrasec. If the check fails, the POS cannot continue.
If the POS cannot connect to the fiscal memory for any reason, LS Central attempts to open the Cash Invoice Form, if available.
POS login validation (Infrasec requirement)
When logging in to the POS, LS Central sends a request to Infrasec to verify the server connection status.
- If the connection is successful, the POS login continues as normal.
- If there is an issue connecting to the server, an error message is displayed in the POS, indicating that the connection check failed.

Cash Invoice Form
The LS Central solution for the Swedish fiscalization supports the possibility for the POS to continue to sell in cases when there is a connection problem to the physical memory, either Type A or Type C.
This is when the POS cannot connect with the e-Tax Control Unit or Infrasec to deliver needed information to tax authorities.
- The Cash Invoice Form opens automatically when the POS fails to register fiscal information.
- To finalize the sales in the POS, the cashier must fill in the following:
- Customer Name.
- Customer Address, one field for the whole address.
- Customer Phone Number.
- When the Cash Invoice Form is used, the POS law is not applicable, instead it is the “Bokföringslagen” (accounting law).
- Note that the store ensures the correct customer data is keyed in.
Note: The POS manages to finalize a sale, that is, to post the sale to the transaction register without managing to post its fiscal information.
POS finishes the sale without posting fiscal information
It can happen that the POS manages to finalize a sale, that is, to post the sale to the transaction register without managing to post its fiscal information.
In such a case, the POS Terminal is in state Out of Order for the fiscal information and does not start a new sale.
What you can do in such a case:
- Open the Transaction Register page.
- The last sale that caused the error is, by default, the active one.
- Make sure the last sale is active.
- Select the button Print Copy.
- The system automatically opens the Cash Invoice Form and lets the user fill in the information as usual.
- Enter information into the Cash Invoice Form and click OK.
- The POS should now be ready for the next sale.
