Staff Switch & Login¶

During operations, multiple employees work on the same device. DiKAS offers three login methods — PIN, NFC card, and password — for a quick switch without interrupting service.

Method	Speed	Security	Setup
PIN (4-digit)	Fast	Medium	Admin → Staff → Set PIN
NFC card	Fastest	High	Admin → Staff → Assign card ID
Password	Slow	High	Admin → Staff → Set password

POS menu with staff switch

Tap the employee name in the header bar
A list of all active employees is displayed
Tap your name
Enter your 4-digit PIN
You are now the active waiter

Hold the NFC card to the reader
DiKAS recognizes the card automatically and logs the employee in
No tapping, no PIN — ideal for a quick switch at the counter

Setup: Admin → Staff → [Employee] → Fill in the field "Card ID" with the card number. Instead of typing the number, tap the "Read NFC card" button next to the field and hold the card to the reader — the ID is captured automatically.

Supported card readers¶

Almost any common NFC/RFID reader can be used for card login. DiKAS connects the hardware in four ways:

Reader type	Platform	Connection
Built-in NFC (smartphone/tablet)	Android	Direct, no accessory required
Any PC/SC card reader (standard smartcard reader)	Windows PC / POS	Via the local hardware bridge DikasArch
Baltech NFC reader	Windows PC / POS	Via the local hardware bridge DikasArch
HID / keyboard-wedge readers (output the ID as keyboard input)	All (browser/PC/Android)	Direct — the card ID is recognized like a keyboard entry
USB NFC reader ACR122U	Android	Via the built-in USB NFC plugin

ℹ️ PC/SC and Baltech readers on the PC/web POS: The reader is connected via the local hardware bridge DikasArch running on the workstation, which delivers the card ID to DiKAS. Enable the "Local hardware bridge (DikasArch)" switch in the POS settings. HID readers that send the card number as keyboard input also work without the bridge, directly in the browser.

Used for the login screen (e.g., after a restart or for Admin login). During regular POS operations, you typically use PIN or NFC.

Opening a Shift¶

When the first staff switch of the day occurs, a shift (Exchange) is automatically opened. You can also manually open a shift with an opening balance:

Perform a staff switch
Tap "Open shift"
Enter the opening balance (change in the register, e.g., 200.00 EUR)

The opening balance is used in the end-of-day report as the starting value for the cash count.

ℹ️ Note: There is exactly one open shift per employee and business day. If a shift is already open, it will be continued.

Assignment of Transactions¶

All actions at the POS are assigned to the currently logged-in waiter:

Action	Assignment
Taking an order	Waiter on the order ticket
Processing payment	Waiter on the receipt
Void	Waiter who performs the void
Occupying a table	Waiter is assigned to the table
Recording an expense	Waiter on the expense
End-of-day report	Waiter in the Z-report

Own Tables¶

If the permission "Own tables only" is enabled:

The waiter sees only tables assigned to them
Other waiters cannot edit these tables
Exception: Employees with the permission "Pay all tables" can also check out other waiters' tables

Typical scenario: In a restaurant, each waiter has their own section (e.g., terrace, indoor area). Each waiter sees and serves only their own tables.

Waiter Settlement¶

At the end of a shift, each waiter can view their own settlement:

Menu → "My settlement"

Waiter: Maria Schmidt
Shift: 05.03.2026, 11:00 – 22:30

Opening balance:       200.00 EUR
+ Cash revenue:        312.80 EUR
+ Debit card:          124.50 EUR
+ House tab:            50.00 EUR
− Expenses:            −15.00 EUR
────────────────────────────────────
Total revenue:         487.30 EUR

Receipts:    23
Voids:        1 (8.50 EUR)

The settlement shows only the waiter's own revenue — other employees see only their own figures (unless the permission "View reports" is set).

Closing a Shift¶

Prerequisite: The permission "Close shift" must be enabled.

Menu → "Close shift"
Count the register contents and enter the amount
DiKAS compares expected and actual balance:

Expected balance:    497.80 EUR
  (Opening 200 EUR + Cash 312.80 EUR − Expenses 15.00 EUR)

Counted:             495.30 EUR
Difference:           −2.50 EUR

Optional: Enter a closing note
Confirm "Close shift"

The shift data feeds into the end-of-day report.

Automatic Lock¶

After a configurable period of inactivity, the device is locked:

Admin → Settings → Operations → "Auto lock"

Setting	Description
Lock time	Minutes until automatic lock (0 = disabled)
Lock screen	Appears after the inactivity period expires
Unlock	Via PIN, NFC card, or password

Workflow¶

No input for the configured time → Lock screen appears
Next employee logs in (PIN, NFC, or password)
All subsequent transactions are assigned to the new employee

💡 Tip: Enable auto lock with 3–5 minutes. This prevents transactions from being assigned to the wrong employee.
