FAQ

Requirements and procedure

A FEIG TOPP Payment Terminal can only ever be used in combination with an acceptance contract from a network operator. A constant, stable internet connection is also required. Here is the process:

The operator, or the one who receives the revenue from the machine, concludes a contract with a network operator of his choice. With FEIG Terminals, the configuration of the terminal is also determined at the same time. The customer can, for example, specify directly in the contract which payment systems should be supported and how often billing (till cut) takes place.

The customer then receives a TID (Terminal ID, eight-digit number) from the network operator for each machine. Now the terminal can be installed in the machine and the internet connection can be established. With the FEIG configuration tool CRS, the TID is stored in the terminal and the automatic commissioning is started.

Full details and step-by-step instructions can be found in our "Commissioning Guide"

For new customers or newly developed machines, the network operator usually also requires a one-off receipt. You can find all information about this under the point "What is a receipt".

What are network operators?

Network operators are payment service providers represented in Germany. These provide the counterpart for the terminal and take care of the further processing of payments. They ensure that the account or credit card of the machine user is debited and that the merchant is credited with his earnings bundled. They also provide logs and accounts. You can find more information on this topic on the homepage of the Federal Association of EC-Cash Network Operators at www.b-ec-n.de.

With which payment service provider / network operator can the terminal be operated?

A list of the available network operators can be found in the download area. This list is expanded regularly, so always use the latest version.

Please note that the choice of network operator cannot be changed afterwards. Each network operator needs its own software and security certificates. These are loaded into the terminal in a secure environment during production and can no longer be changed. However, the network operator contract and the terminal ID can easily be changed by the customer. This is comparable to a net lock on a cell phone; here, too, the SIM card and telephone number cannot be changed, but the cell phone operator cannot be changed.

What is a receipt acceptance test ("Belegabnahme")?

A receipt acceptance test  is a functional test of the operational machine with payment system. This is common for new machines or new customers and has to be done once. The network operator provides a special TID (Terminal ID) for this. The terminal thus establishes a connection to a separate test system of the network operator.

Various payments are made during acceptance and the results are recorded. For example, payments under 50 euros are made, these are authorized by the test system, payments over 50 euros are rejected. FEIG terminals provide the payment receipts electronically, these can be read out with the FEIG CRS tool and copied into the receipt form.

Trial payments must be made for each payment system used and special test cards must be used.

After the receipt of the receipt has been completed, the form is submitted to the network operator, who checks the accuracy and completeness by comparing it with the test system and then issues an approval.

Where can I get terminals and test cards for receipt acceptance?

For receipt acceptance tests, FEIG distributors or FEIG directly provide a test system with a fully configured terminal and suitable test cards.

Cards & payment systems

FEIG terminals support all common credit, debit and prepaid cards. These include VISA, V-Pay, Mastercard, maestro, American Express, Discover, JCP, Union Pay and mobile payment based on Apple Pay and Google Pay. Other national and international card systems can optionally be added.

In order to accept payments, the desired card systems must also be supported and activated by the network operator / acquirer. These are listed in the acceptance contract and must be activated accordingly.

How can further payment systems be added?

FEIG optionally offers the implementation of further card systems, both open loop cards based on EMV and closed loop systems based on ISO14443. Alternatively, customers can independently add further applications and card systems using our optional SDKs and our secure Kaas (Keychain as a Service) infrastructure. You can find further details under [Payment Kernel Development]

What about other payment systems like Alipay, WeChatPay, Bluecode ...?

Our terminals currently support all common payment systems that are standardized in accordance with the global EMV standard and that work contactlessly in accordance with ISO14443 or NFC. For some terminals, e.g. the cVEND PIN, we optionally offer an optional hybrid card reader for chip cards and magnetic strips.

Many other systems such as Alipay, WeChatPay ... come from the app payment or online payment area and rely, for example, on QR codes or a special smartphone app. These systems are currently not supported by our terminals.

Do the terminals support mobile payment e.g. Apple Pay & Google Pay?

FEIG terminals offer complete support for Apple Pay, Google Pay and many other wallet solutions such as Samsung Pay, Fitbit Pay ... However, it should be noted that these are not payment systems. Apple and Google provide an infrastructure and an "empty wallet" which the customer can fill with cards, e.g. a digital Mastercard. When paying, the smartphone emulates a contactless card and from the point of view of the payment terminal it is a "normal" contactless payment. It is therefore important that the corresponding card system is available and activated in the terminal, in this example Mastercard.

Do FEIG terminals support Diners Club cards?

Diners Club uses the Discover card system as the technical basis, which is supported by all FEIG terminals. The Diners Club card can therefore be used without any problems, but it must be ensured that the corresponding card system is activated in the network operator contract, in this case the Discover system.

Can I pay with my smartwatch?

All common smartwatches, key fobs and other designs that use the same wallet / digital card technology as smartphones are supported by FEIG terminals. Here, too, it should be noted that the card system used must be activated in the payment terminal (see Mobile Payment).

To help you find the right terminal for your application, we offer our cVEND payment terminals in different configurations.

The flex version is a developer version. It comes with a fully configured payment operating system. Two SDKs allow you to integrate individual closed-loop and open-loop applications as needed.

We also offer a range of ready-to-use terminals that can be integrated quickly and easily. The TOPP and DE variants have a German payment application and are ideal for terminals that will be used in Germany. With the Redsys variant, we have designed payment terminals specifically for the Spanish market. The NMI variant, on the other hand, enables integration in almost all European countries via the NMI Payment Gateway.

How do I get support for my terminal?

The first point of contact is always the dealer from whom you purchased the terminal. They help with problems and, if necessary, takes over the repairs with FEIG. If you bought the terminal directly from FEIG, you will find all the information you need here. Please do not send any terminals in unsolicited, our support system will automatically generate a ticket and you will receive a return number (RMA number) with which your terminal can be assigned.

How do I find the serial number and the device ID of my terminal?

Every FEIG terminal has a nameplate on the back of the device. At the top right you will find the serial number (behind SN :) and the device ID (behind Dev.-ID :). Please always quote both numbers with all inquiries.

How do I find the TID (Terminal ID) of my terminal?

The TID (Terminal ID) is not specified during production, but is assigned by the network operator and only entered during commissioning. There is a unique terminal ID for each terminal. You can find this in your contract documents. Alternatively, the terminal ID can be determined using the FEIG configuration tool CRS. You will find the terminal ID in the "** Host configuration **" section of the system data printout. You can find detailed instructions on how to use our CRS tool and how to display the configuration in our commissioning guides.

How do I get updates, drivers, software & documentation?

You can find all the documents you need in your customer download area at www.feig.de/login. There you can also register as a new customer. Alternatively, each terminal is accompanied by short, printed instructions that also contain access data for all information, software and updates for the respective terminal.
