The German company EBG compleo develops electric vehicle charging points that are sold worldwide. To win the contract for the “be emobil” charging points project for the city of Berlin, EBG compleo developed a solution that uses RFID to provide contactless access control at charging points.

The key requirement of the project was: The RFID technology with VDV-KA protocol already used in the public transport system will continue to be used for user authentication at the electric charging points.


  • The reader/writer has to support RFID technology with the VDV-KA protocol.
  • The reader must be easy to configure and accept remote updates to minimise maintenance costs and ensure worldwide use.

Successful outcomes with comprehensive RFID

The multifunctional RFID reader supports more than 60 RFID technologies, including the VDV-KA protocol

Until now, EBG compleo had no experience whatsoever in the RFID segment and therefore relied fully on the combined expertise of ELATEC. The comprehensive know-how, high-performance, and reliable products, and outstanding support played a key role in the success of the project.

It recommended the TWN4 MultiTech as the most suitable RFID reader/writer for the application. The multifunctional RFID reader supports more than 60 RFID technologies, including the required VDV-KA protocol. The TWN4 MultiTech was installed directly in the charging points to ensure optimal integration.


  • ELATEC TWN4 MultiTech reads more than 60 card technologies, including VDV- KA.
  • Thanks to remote configuration, updates can be conveniently installed without on-site technician assistance.


  • The existing RFID cards with the VDV-KA protocol enable trouble-free user authentication.
  • The multi-frequency capability of the TWN4 MultiTech means that authentication can also be expanded to include cards with other RFID protocols in the future.
  • EBG compleo offers its charging points with RFID authentication throughout the world.

A future-proof authentication solution

Due to the extremely versatile TWN4 MultiTech, EBG could and can provide charging points solutions with future-proof authentication technology – and not just for the city of Berlin, but for international users as well. The reader recognises and reads all standard RFID systems worldwide. It also features remote configuration and can be quickly and easily updated and configured from a distance.

A critical advantage, especially for manufacturers who sell their products around the world. This also won over Dag Hagby, CEO of the EBG group, “The flexibility of the multi-frequency reader from ELATEC allows us to respond globally to the requirements from a wide range of RFID protocols in cities and municipalities.” EBG compleo has since opted for RFID readers/writers from ELATEC for authentication consistently.
