The challenge: Reducing waiting times at the bar
One of the biggest frustrations for event visitors is standing in long queues, particularly at bars. At many festivals and events, this is caused by the widely used token system. Visitors first queue to purchase tokens and then wait again to use them at the bar. For both staff and guests, counting and handling these tokens is time-consuming and inefficient. The need for a faster, more streamlined solution was clear.
The solution: TurboPOS
Sjef. developed TurboPOS, a fast, easy-to-use POS system that accepts all major payment cards directly at the bar, eliminating the token process. To ensure reliability and efficiency, they partnered with ProDVX. The APPC-10SLB Android Panel PC was the perfect fit thanks to its stable performance, integration options, and Surround LED bar, which gives instant visual feedback on payments and speeds up service while enhancing the festival atmosphere.
The results & benefits for event organisations
TurboPOS was successfully rolled out at major events such as Awakenings, No Art ADE, and Intercell, delivering clear benefits for both visitors and organisers:
For visitors:
-
Faster orders and payments, reducing queuing time
-
No need to queue at token machines
-
A smoother and more enjoyable event experience
For organisers:

Yeri from Sjef. summarised the collaboration as follows:
With ProDVX as our partner, we made our POS solution safer and faster than any other POS solution on the market today.
