Payment division

The Payment division offers credit cards for private and corporate customers. It also handles card acceptance and processing for its affiliated partners and provides payment terminals.

Issuing – issuing of cards

Viseca is one of the largest issuers of credit and PrePaid cards for Mastercard and Visa in Switzerland. Viseca’s private and corporate customers benefit from a broad range of products and services. 

Acquiring – card acceptance, payment processing and payment terminals

As acquirer, Aduno makes sure that customers can pay its affiliated partners conveniently and securely with all credit and debit cards commonly used in Switzerland. To be more concrete, it handles the acceptance and processing of electronic payments at points of sale and makes available the physical payment terminals.

Interaction between Issuing and Acquiring

The Issuing and Acquiring segments are closely interlinked. When customers need a credit card, they can apply for one from an issuer such as Viseca. The issuer guarantees that the card will work anywhere in the world, manages the cardholder’s account and charges the credit card transactions to the cardholder. The issuer also pre-finances the transactions on the card for the period between the transaction and the payment of the outstanding balance. For these services the cardholder pays the issuer a card fee. As issuer, Viseca is a licensee of the international card companies Mastercard and Visa.

Merchants who wish to accept card payments must work together with an acquirer such as Aduno. The acquirer forwards all transaction data to the relevant issuer and pays the purchase price to the merchant within a few days. Merchants pay the acquirer a fixed or percentage commission on every transaction. The issuer receives part of this commission from the acquirer in the form of an interchange fee. To guarantee acceptance of the cards, Aduno is also a licensee of card companies such as Mastercard, Visa and UnionPay.


AdunoKaution is a leading provider of deposit guarantees, a modern alternative to traditional bank deposits. In conjunction with its product and distribution partner Generali Insurance, it sells guarantees for rental deposits throughout Switzerland.

E-commerce and m-commerce on the way to the future

Thanks to our integrated business model, we are ideally positioned to offer our customers electronic and digital products and services. E-commerce and m-commerce applications link cardholders, affiliated partners and partner banks so that they optimally complement one another and create added value for all parties. 

Contactless technology is gaining in popularity among customers on both sides. Customers who have a credit card with contactless function only need to hold the card against the payment terminal to pay for their purchases. Cardholders and merchants alike benefit from fast, convenient payment processing with the same level of security. Viseca pioneered contactless technology in Switzerland.

With mobile contactless payment, customers simply hold their smartphone against the payment terminal to conduct a contactless payment transaction. The functions that are normally stored on a card are also stored on the smartphone and are transferred by NFC technology when the phone is used to pay for a transaction. As the Aduno Group is involved in both issuing and acquiring, it has gathered experience with contactless payment on both sides, which makes it a popular partner in the mobile contactless payment business.
