Your benefits

146 million giro & credit cards in Germany alone
Every electric driver worldwide has one of these cards in his wallet. Therefore each of them is a potential customer for the operator of a wallbe® charging station.

No registration required
Due to the acceptance of the girocard and the common credit cards, no prior registration is necessary. The receipt for the charge process can be easily retrieved online or sent by e-mail on request.

Absolute price transparency
Due to the avoidance of additional service providers, full price transparency is assured. The price per kWh displayed on the wallbe® charging station is actually the price that is charged per kWh at the end. Amounts are invoiced precisely and in conformity with calibration law.

Fair market price
Thanks to the barrier-free payment system, with wallbe® charging stations you always have the possibility to pass on the best price to your customers.

Payment guarantee
Amounts reserved in advance on the customer’s bank account which are finally settled after the charging process ensure a payment process safer than ever. This makes payment defaults a thing of the past for the operator.

Accounting in conformity with calibration law
With the wallbe® concept all requirements for the calibration law are fulfilled according to the specifications of the Physikalisch-Technische Bundesanstalt (PTB) and the document REA 6A.

With the wallbe® billing system “contactless payment with giro – or credit card” we finally offer operators the solution to operate charging infrastructures economically and to bill all users fairly, transparently and cost-effectively.
