### [Ticket System](https://www.error-40.de/en/apps/ticketsystem)

Digital queue numbers for medical practices: take a ticket, see the waiting time, get called.

### Straight in the browser

No app store installation needed. Open the link and get started.

### Reduced to the essentials

A few clear functions instead of overloaded interfaces.

### Built for real use

Developed from concrete everyday situations and improved in use.

Practical web apps like our digital ticketing system, which finally makes wait times fair, transparent, and stress-free.

Whether in a doctor’s surgery, a citizens’ advice bureau, a chemist’s, a workshop or at a service counter: wherever people have to wait, our system ensures order, clarity and a smooth flow of business. Customers collect their digital queue ticket directly via their smartphone – even as a wallet card, if they wish. Staff can see immediately who is next in line, without any paper clutter or people shouting out.

Ideal for:

Doctors’ surgeries (reception, blood tests, lab)

Pharmacies & medical supply shops

Citizens’ advice bureaux & government offices

Workshops & repair centres

Post offices & parcel shops

Restaurants with collection numbers

Small shops with fluctuating footfall

Why choose this system?
Because it simply works. No hardware, no installation, no queues at the machine. You get a modern, easy-to-use system that digitises and speeds up waiting processes, making them more pleasant for your customers. And best of all: it’s so flexible that it can be used in any business – from small shops to large government departments.

Queue tickets reimagined. Digital. Simple. Efficient.
