PEKA is an Android application that allows users to purchase and manage period tickets for public transportation in Poznan and its surrounding areas. It enables passengers to show their tickets on their smartphones during inspections on trams or buses, which are then checked online on their PEKA account.

The app includes most of the services available on the PEKA website, and more details can be found on the ZTM Poznan website. However, to pay for rides based on the number of stops using tPortmonetka, users must possess a physical PEKA card, which can be ordered through the app or the PEKA website.

Users must log in to their PEKA account when they first open the app and upload their current photo. The app allows logging in to the PEKA account only on one mobile device every 24 hours for security reasons. If users do not have a PEKA account, they can create one through the app and immediately use it after their identity is verified through a trusted profile.

Overall, PEKA is a useful mobile application for managing public transport tickets in Poznan, with a simple and easy-to-use interface that makes it convenient for users.
