cVEND box flex I

Contactless payment terminals with housing an secure payment OS

cVEND box

cVEND box and box+ are payment terminals in an extremely robust housing for the standardized EVA cutout of the European Vending Association. This cutout is not only standard in vending machines but is also used in other areas such as parking machines or charging stations. These machines can be upgraded simply by removing the cover and mounting the terminal. The "+" variant (cVEND box+) also has an integrated graphics-capable OLED display. For models without their own display like the cVEND box (without "+"), the terminal transmit their display messages to the vending machine's screen using the standardized MDB or ZVT protocol.


flex I

The flex I variant contains a fully configured payment OS but no level 2 kernel or applications. The target group are customers who want to implement their own payment applications and card schemes and need suitable, PCI-certified hardware for this. Further applications are closed loop and public transport applications that require a high level of security and performance and want to keep an upgrade path to open loop payment open. Customers can develop both kernels and applications independently and independently of FEIG. FEIG provides SDKs and a compiler toolchain for this purpose.




The cVEND box is member of the unattended cVEND contactless payment terminal family is used successfully thousands of times in various applications around the globe and is fully EMVCo and PCI PTS approved.


The robust housing with EVA CVS compliant dimensions enables easy installation in multiple indoor and outdoor applications.


cVEND box is electrically and mechanically suitable for various unattended contactless only  applications like Vending, Parking, EV-Charging and Transit.


It complies with MDB Vending standard as well as with transit specifications of global card brands and railway and automotive standards.


It supports open-loop contactless payment cards and mobile wallets from international and domestic payment card brands as well as closed-loop cards like mifare, ITSO, VDV-KA, calypso with the same priority.
cVEND is VISA ready for Transit listed


The step-by-step upgrade concept enables migration from closed-loop to open-loop. Level 2 kernel packages can be upgraded later in field.


Its innovative security concepts with Crypto Plug-Ins supports symmetric and asymmetric encryption, key-derivation and remote key loading and makes cVEND capable for PCI P2PE solutions.


The low power standby mode makes it suitable for battery powered application.
