# How to create a payment device (mobile)

A payment device identifies the place from which receipts are issued and has its own receipt-number sequence. Create a new one for a new place of payment, company, business premise or device sequence.

## Before you start

Prepare the business-premise code, payment-device code, fiscalization certificate (.p12) and its password. Add an operator first when a default operator is required.

## Work steps

1. On the bottom bar, tap **Cash register**.
2. Under **Cash register settings**, tap **Payment devices**.
3. Tap **+**, then **Add device**.
4. Select the **Company** when displayed.
5. Enter the device name, default operator, **Business premise**, **Payment device** and opening deposit. Add branch details when needed.
6. Tap **Upload fiscal certificate**, select the .p12 file, enter its password and tap **Unlock certificate**.
7. Review the certificate details and resolve any certificate or OIB warning.
8. Tap **Save**.
9. Set the device as default and review its payment methods before issuing the first receipt.

|| Important: The certificate holder's OIB must match the OIB configured for the device. Do not issue receipts until a mismatch or certificate warning is resolved.

|| Important: Create a new payment device when the business premise, payment-device code, company, physical place of payment or receipt-number sequence changes. Edit the existing device only for settings that do not require a new sequence.
