RudelCashOrdered, printed, paid.
RudelCash gets the club party moving: the helpers take orders on their own phones, the tickets come out of the printers at the bar and in the kitchen, and payment happens at the table. Everything runs on the local Wi-Fi – even with no internet at all.
- service phones on Wi-Fi
- receipt printers: LAN, USB, Bluetooth
- tabs
- NFC tables
- kitchen monitor
- card terminal
From the first beer to the final count
Ordering on one screen
Tap a table or hold the phone to its NFC sticker, pick items, send. Variants and options such as “large portion” or “no onions” are quick to choose, and “Undo” replaces confirmation prompts.
Tickets for bar and kitchen
Each item belongs to a print group, and the ticket comes out of the right receipt printer (58 or 80 mm) – on the network, by USB cable or Bluetooth. You design the ticket layout yourself; the kitchen can also use a monitor instead of paper. Before the party, “Ready?” checks everything and sends a test ticket to every printer.
Tabs instead of rigid tables
Orders go onto a tab – “Table 12” or “Miller family”. Two groups at one table or one family at two tables are no problem; items can be moved between tabs.
Paying across several tables
In the payment basket you collect items from several tabs: “Grandma pays for everyone” or “everyone pays their own”. Change calculator with notes and coins, tip, deposit and discount.
Card payment
A card terminal on the Wi-Fi that speaks the open ZVT protocol receives the amount directly from RudelCash. The club gets the terminal and contract from its bank or provider.
NFC and QR tables
The app writes one NFC sticker per table itself; for phones without NFC the receipt printer prints QR table cards. You lay out the tables in the floor plan – drag, rotate, move several at once. Floor plans can be saved and loaded again.
Stock and reports
Stock per event with +/− right in the list, stocktaking, deposits and sales by item, helper and hour. Plus a settlement per helper to print. Everything as CSV for the club treasurer.
Events and price lists
Prepare events, use the last party as a template (settings, print groups, opening stock, floor plan), reuse price lists or maintain them as CSV. A practice mode to train the helpers.
One job per device
Each device gets its role: service, bar till, kitchen or admin. Everyone sees only what they need – the setup stays with the admin.
Not included yet: connecting a TSE (the technical security device required for tills in Germany). Without it RudelCash is not yet a till within the meaning of the German Cash Register Security Regulation (KassenSichV) – see FAQ.
Uses what the club already has.
No rental devices, no special printer, no account and no internet: RudelCash is made for the club party, not for running a restaurant.
Any receipt printer will do
ESC/POS receipt printers on the network, by USB cable on a tablet (with an OTG adapter) or via Bluetooth. The old printer from the clubhouse works too – no tie to one manufacturer.
The helpers’ own phones
Helpers take orders on their own Android phones. No rental devices that need charging before the party and collecting afterwards.
No internet, no account
Everything runs on the local Wi-Fi. No account with a provider, no cloud – the data stays with the club, even where the venue has no signal.
Free choice of card terminal
Any terminal that speaks the open ZVT protocol, from the provider the club already uses.
Keeps going when things go wrong
If the hub is unreachable, the service devices print themselves and catch up later. If it fails for good, another device becomes the hub with its copy.
Just like at the party table
Tabs and a payment basket instead of rigid tables: separately or together, across several tables. At the end, a settlement per helper.
One Wi-Fi router is enough. No internet needed.
One device is the hub – ideally a tablet at the till, but a phone will do. It numbers the tickets, keeps stock and accounts and sends the print jobs to the printers. The other phones pair by QR code.
Orders are buffered on the phone and go out as soon as the Wi-Fi is back.
The service devices work with their own copy of the data and stay quick even with weak reception. If the hub fails, another device takes over.
Only paired devices get in. Resetting orders requires the device’s fingerprint or PIN.
No account, no cloud, no advertising
RudelCash stores everything on the event’s devices and only talks to devices on the local Wi-Fi: the other phones, the receipt printers and, if you like, the card terminal. All details
Stays with the club
Orders, sales and helpers are stored on the club’s devices – not with me and not in a cloud.
Cards stay at the terminal
Only the terminal processes card data; RudelCash only learns whether the payment went through.
No ads, no tracking
No analytics, no advertising, no crash reports.

FAQ
Can the club already take real money with RudelCash?
Not yet. In Germany, anyone taking payments electronically needs a certified TSE, must register the till with the tax office and provide data for cash inspections. Connecting a TSE is in preparation. Until then RudelCash is meant for trying out and practising. Please clarify your club’s obligations with your tax adviser.
Do we need internet at the venue?
No. A Wi-Fi router on site connects phones, hub and printers. Internet is needed at most by a card terminal that has to talk to its payment service.
Can the helpers use their own phones?
Yes. Install the app, scan the hub’s QR code, done.
What happens if a phone fails?
Simply replace a service phone with another one – the orders are stored at the hub. If the hub is unreachable, the service devices print themselves and catch up later; if it fails for good, another device becomes the hub with its copy of the data. Still, best keep the hub plugged in.
Which receipt printers work?
Receipt printers with the common ESC/POS command set, 58 or 80 mm wide. All devices can reach a network printer. A printer connected by USB (to a tablet or phone with an OTG adapter) or Bluetooth is reached only by the device it is attached to – when several devices work together, that is the hub, which then prints for everyone. Pair Bluetooth printers in the Android settings first.
