Starting today, you can go to 3,000 grocery stores, drugstores and other retail chains in Germany to withdraw and deposit cash. Withdrawing cash isn’t really important as you could already use any MasterCard ATM to get cash from your Number26 account. But depositing cash is a new feature for the company. All you need to do is show up at a checkout register with your phone. Inside the Number26 app, look for the new Cash26 feature, enter the amount of cash you want to deposit or withdraw and scan a barcode. You then need to enter your PIN code. Cash deposits immediately appear in your bank account.
