Sparkassen will shut down the S-ID-Check app on January 31, 2027, consolidating payment authorization into the existing S-PushTAN app. The move affects approximately 50 million retail customers across Germany. Currently, customers use S-ID-Check to approve card transactions and S-PushTAN for online banking, requiring two separate apps. The merger reduces installation steps and registration burden while reflecting a broader digital banking trend.
Why Sparkassen is killing the S-ID-Check app
Sparkassen customers currently juggle two apps to authorize payments. S-ID-Check handles credit and debit card approvals using two-factor authentication like fingerprint or facial recognition. S-PushTAN manages online banking transactions. The consolidation reduces installation and registration effort, according to the German Sparkassen and Giroverbund (DSGV). Bundling payment functions into one system also lowers costs for the banks.
What customers must do before the deadline
Users who already have S-PushTAN installed can simply add their card details to the existing app. Those without S-PushTAN must download and set up the app, then register their cards once. Sparkassen branch staff can assist with registration at local offices. After January 31, 2027, the S-ID-Check app will no longer function for payment authorization.
Physical card redesign rolls out in parallel
Sparkassen is issuing 14 million new Sparkassen-Cards and 1 million credit cards with redesigned layouts starting in 2026. Card numbers, IBAN, expiration dates, and security codes move to the back of the card. The traditional signature strip disappears entirely. Existing cardholders receive new versions only when their current card expires naturally. No forced exchange is required. Roughly 47 million Sparkassen-Cards and 10 million credit cards are currently in circulation.
Digital banking adoption accelerates across Germany
The app consolidation reflects broader trends in German banking. Eighty-six percent of Germans now use online banking, up significantly from prior years. Cashless payments surpassed 55 percent of daily retail transactions in early 2025 for the first time. Sparkassen’s strategy to concentrate banking functions on fewer mobile platforms mirrors industry-wide moves toward streamlined digital experiences and reduced operational costs.
Final Thoughts
Sparkassen’s merger of payment apps on January 31, 2027, streamlines customer experience while cutting bank costs. Customers must migrate to S-PushTAN before the deadline or lose card payment authorization. The shift reflects Germany’s accelerating shift toward digital-only banking.
