Gastro 3.0: M2M SIMs for digital payment solutions at events

Staff shortages, lack of manpower or changing guest requirements - in the catering industry, digitalization helps with precisely these challenges. In particular, the ordering and payment processes at events and festivals can be streamlined and accelerated with the use of digital ordering platforms. This is exactly what the Stuttgart-based company sizzly offers: they provide a web app for digital ordering and payment solutions in the catering, event and entertainment industry. 

The company relies on M2M SIM cards and the connection to the mobile network for reliable data transmission. Thanks to uncontrolled roaming, several networks can be used at one location. If you need a reliable connection for your project, you can buy a suitable M2M SIM card from us and benefit from optimum network coverage. Access to the strongest local network ensures that everything runs smoothly, even at busy festivals and sporting events.

Digitalization in the hospitality and event industry

A break between two halves of the game and a quick trip to the drinks stand - and you're already standing in a long queue. 

This is where sizzly's digital self-ordering solution comes into play. The digital ordering and payment processes are handled via a smartphone platform: Food and drink offers can be called up, (re)ordered and paid for via a web app. Always in the customer's CI and with a customized concept.

At an event or festival, but also in the canteen, customers can simply order via their own smartphone without the need for a separate app. The result: less waiting time and therefore increased customer satisfaction, bringing the catering experience into the digital age. 

Here’s how it works in practice: At a festival, for example, visitors can scan a QR code and order their drinks via smartphone from anywhere on the grounds, paying immediately. After receiving an order confirmation, they can bypass the regular lines at the food trucks and bars and pick up their drinks quickly and cashlessly. The details of the orders placed, as well as proof of the transaction, are transmitted directly to the bars. There, they are displayed on smartphones or tablets provided by sizzly. The necessary data connection is provided by WhereverSIM’s M2M SIM cards.

Contactless ordering and payment not only makes the service more efficient, but also more customer-oriented. Staff at serving and dining trolleys no longer have to deal with a cash register system or cash handling, and more and more manual processes are eliminated. This not only saves costs, but also significantly improves the workflow.

IoT SIM cards for self-ordering and cashless payment

sizzly provides restaurateurs and caterers with a full-service package consisting of a branded ordering front end, the web app in the customer's CI and the hardware required for issuing orders - including M2M SIM cards and a reliable mobile connection. 

“You may have experienced this yourself at your last festival or concert—when there are a lot of people there, it can sometimes take a while for your smartphone to connect. That’s exactly what we don’t want to happen on our digital self-ordering platform,” says Raphael Büdel, co-founder and CEO of sizzly. To ensure this, the company relies on WhereverSIM’s M2M SIM cards. Thanks to unmanaged roaming, these cards always connect to the strongest local network, allowing them to switch to another available network when network congestion is high.

The M2M SIM cards are used in the tablets that run the point-of-sale and inventory management system. Orders and payment receipts are transmitted in real time to the tablets in the bar and dining cars. This ensures smooth operations and satisfied customers.
