The Zelisko validator is far more than a simple control device – it is an intelligent and modern standard solution for e-ticketing in public transport.
Thanks to its compact design, integrated payment function, and support for current ticketing standards such as VDV-KA as well as ID- and account-based ticketing (IDBT/ABT), it enables seamless, contactless, and future-proof passenger processing. Whether barcode, smartcard, or contactless payment via bank card – the validator detects, validates, and processes all common media quickly and reliably.
