The problems with card payments in many German supermarkets could drag on for days. Although there is now an update for the affected payment device from the US manufacturer Verifone, the Frankfurt service provider Payone announced on Saturday. However, the version is not stable enough to be used across the board.

Since Tuesday, many thousands of customers can no longer pay with giro or credit cards at German retailers. Among other things, branches of Aldi Nord, Edeka or the Edeka subsidiary Netto are affected. The reason for this is a malfunction in the widespread Verifone device H5000. It is used by Payone and its competitor Concardis, among others. The service providers provide the devices and process the payments. The terminals themselves and the software for them come from Verifone.

Manual intervention on site by either the retailer or a technician is required to restart the devices, Payone said, citing Verifone. All available resources for the update have already been pulled together. “Nevertheless, we assume that this process cannot be carried out ad hoc in the area, but will probably take a few days,” said a Payone spokeswoman. Irrespective of this, alternatives would be developed so that cards could be accepted again as quickly as possible.

Verifone said it is working on the solution with customers and partners. This has been available since Friday. “We would like to emphasize that the issue is not related to a certificate expiration or vulnerability and does not pose a security threat,” the statement said. Rather, it is a software malfunction. Previously, there had been speculation that the problems could be due to an expired certificate that confirms the identity of a computer or other electronic device.

The disruption has been causing trouble in retail for days. Many customers can only pay for their purchases with cash. If the giro card (formerly EC card) does not work, it is no longer possible to withdraw cash at the supermarket checkout.

Cashless payments have been given a boost in Germany by the pandemic. The share of sales from card payments in stationary retail rose from 50.5 percent in 2019 to 58.8 percent last year, according to a study by the Cologne retail research institute EHI published in early May.

Contactless payments, where cards or smartphones are held in front of the terminal, have also become part of everyday life due to the pandemic. For smaller amounts, it is often not necessary to enter the PIN, so customers do not have to touch the payment terminal.

According to the “Süddeutsche Zeitung”, insurance brokers report that Allianz wants to get rid of hundreds of medium-sized companies by increasing prices by up to 400 percent. Property insurance, which companies use to protect themselves against fire, storm damage and business interruption, is affected.

In order to relieve low and middle incomes from rising energy and food prices, Social Affairs Minister Hubertus Heil wants to introduce a social climate allowance for people with a monthly gross income of less than 4000 euros.
