Comments on ČSOB Smart Key for Android

★★★★★ Jakub S. Paulovic · May 16, 2025

Just works, including notifications. Very simple and convenient to use.

★★★★☆ Tomáš Náprstek · Feb 19, 2025

I was perfectly happy with this app until I purchased the new phone(Honor Magic7 Pro) recently. Since then the biometric verification has failed to work returning the message "Failed to initialize biometric reader."! Pitty, I hope it will get fixed soon.

I got blocked by the bank for no reason, then as part of unblocking I had to update the smart key app to this v 3.18.0. It gets stuck during activation - the activate button does nothing just spin the hourglass. The older version 3.10.0 worked fine. The bank staff says the only option to fix this is to upgrade my phone. I figured it's more economical to change the bank... These banking/key apps are a nightmare, plus not anymore secure than sms, but I guess they need to generate jobs.

Impossible to approve payments, switching between other app and Smart Klic cancels the payment verification. Basically I need 2 phones now to create and approve payments in 2023. Android 10, no workarounds found. As a client since 2007 I am very unhappy with this.

★☆☆☆☆ Kristýna Černá · Dec 5, 2023

For more than one week I haven't been able to use the mobile banking app as the csob smart key cannot be paired with my account. Since reporting the issue to the helpdesk (more than 1 week ago), no-one has proactively gotten in touch with me to let me know what is wrong. I would also expect that helpdesk colleagues can find the entry in helpdesk system, so I would not need to explain what is wrong every time I call to find out what is the state of the issue. Edit: I haven't received any incident NR
