KarL4 is SECO's innovation for contactless payment for the Girocard, Mastercard and Visa card. The payment terminal runs entirely without a PIN pad (TOPP) and allows quick age verification on request. This enables customers to pay securely and intuitively with Girocard contactless amounts up to 50 Euros without entering a PIN. KarL4 uses Near Field Communication (NFC) for data communication with the credit card. This ensures extremely customer-friendly handling: pull out your card, put it near KarL4, and pay.

KarL4 uses Near Field Communication (NFC) for data transmission.

A payment service provider (PSP) is a business entity that provides online services for accepting electronic payments. They act as a link between the customer and the merchant, connecting the buyer and seller through a secure payment gateway. They provide merchants with the ability to accept credit cards, debit cards, bank transfers, and other online payment methods. PSPs also offer fraud prevention services, customer support, and other services. The standards include credit cards (Amex, Mastercard, VISA, Discover, UnionPay, ApplePay and GooglePay) or the girocard.

A payment system is a network that facilitates the transfer of money from one party to another. It involves the use of digital payment methods such as credit cards, debit cards, and other electronic funds transfer (EFT) methods. The payment system typically involves a payment processor, which is the intermediary that facilitates the transaction. The payment processor may be a bank, an online payment gateway, or a third-party financial services provider. The payment processor generally works with the customer’s bank to authorize and process the payment request. Once the payment is authorized, the payment processor sends the information to the merchant’s bank, which then sends the funds to the merchant. The merchant typically receives the funds within 1-2 business days.

 

About girocard contactless

The girocard (formerly EC card) is the most widely used card in Germany. By the end of 2021, 96% of all girocards were already equipped with the contactless payment function. The girocard meets the highest security standards of the German banking industry. NFC technology, which makes secure contactless payment possible, is the linchpin for new applications that make the girocard even smarter and more convenient.

 

  • Just hold it close to the payment terminal and you're done.
