How to see if your charging card gets rejected

The charger makes a long beep sound
Via the web portal

How to fix
First, you need to find out who is rejecting your charging card. Are you using just our software or is a third party also connected to your charger?

Check if there is just one server, or multiple
If it's just us, then your charger is only connected to Volt Time.
If there are multiple servers, check who is set to "Leader". This is the backoffice that must recognise and accept your charge card.

If you're an employee or operating a public chargepoint, it's possible your charger is connected to another backoffice via our Proxy. This means the charger is connected to two or more backoffices at the same time.
Often, this means our card authorization gets overruled. Any charge cards you add to our platform must also be recognised and accepted by the 3rd party backoffice that your charger is connected to.
For employees charging at home
Ask your employer to whitelist your charging card.
For operators of a public chargepoint
If the charging cards of your visitor gets rejected, you should check the following:
Is the charger setup correctly?
The chargepoint should be set to be publicly available. If your charger is set to a private mode where only certain charge cards are accepted, the public charge cards of your visitors will be rejected.
Are the cards covered by your roaming partner?
If you are using backoffice provider A to set your charger public, and someone with charging card provider B wants to charge, the two must accept each other. This usually happens in two ways
Your provider and the visitor's provider must communicate with each other. If this is not the case, then:
Your charger must be connected to a 3rd party roaming network that matches cards and chargers from multiple providers. If your charger or the customer's charging card are not in this same roaming network, the transaction is rejected.
Still no luck?
It's possible your charging card is being rejected because the charger itself is rejecting it. Check the settings of your charger and make sure any local whitelists are disabled.
Check your charger's manual or contact your charger's installer if you are not sure how to check this.
