Smart Card Utility FAQ

You are here:

Here are some commonly asked questions about Smart Card Utility.

Where do I find my Activation Code?

Activation codes are no longer required. The app automatically verifies your reader and activates when you first use it. If you are still getting prompted for an activation code, please update the app.

Does Smart Card Utility work with O365?

Yes! Teams may require some special configuration, but you can authenticate to all the O365 apps.

The Smart Card Utility USB-C enclosure has some marks on it. Is there an issue with it?

The USB-C Smart Card Readers enclosures are all 3d printed here so there is a different look that you may be different from injection molded. We test all the readers before sending them out and it should work great.

When I switch between the Smart Card Utility App and another app, the Bluetooth reader turns off. Why is that?

Only one app can use the reader at a time. After connecting to the Bluetooth reader in the Smart Card Utility app, the app will completely disconnect from reader when exiting the app. This causes the reader to turn off. Simply tap the button on the bottom of the reader to turn it back on. Once Safari connects to the reader via our extension, it will remain connected until the reader turns off.

Why does the Bluetooth Reader turn off sometimes?

In order to conserve battery, the Bluetooth reader will turn off when not connected for more than 3 minutes. In this happens, simply tap the button on the bottom to turn on the reader. Then refresh the webpage and authentication will proceed

Why can I only use Smart Card Utility Reader with Safari? Why can’t I use another browser?

Smart Card Utility Utility uses an extension to iOS that makes the certificates on your smart card available to all apps to do an authentication. However, only Safari currently enables this feature. We have escalated the issue with the folks that develop Chrome for iOS and hope they will support it in the future.

I get an SSL error when trying to authenticate to a website. How do I fix this?

See Smart Card Utility: Troubleshooting Website Issues for more information.

I cannot access Microsoft Teams. How do I get it to work?

Some organizations only allow access to the web version of teams and iOS tries to redirect to the app. To resolve this, see the Accessing Microsoft Teams on iPhone and iPad With Smart Card Utility for DoD Customers article for how to access Teams.

How long does the battery last with the Bluetooth reader?

The battery lasts for about a week with normal usage. It takes about an hour to charge up to full capacity.

Can I use the USB-C, Lightning, or Bluetooth reader with my Mac or PC?

Yes! On the USB-C and Lightning Readers, you must use the Micro-USB port on the side of the reader when connecting to your Mac or PC. You will need to use the Micro-USB or USB-C connector on the Bluetooth reader to connect to your Mac or PC. If you have a USB-C port on your computer, you may need a USB-C to USB-A adapter (not provided) to connect to the computer.

Does the Smart Card Utility App work with other readers?

Smart Card Utility App enables smart card authentication only on supported readers from Twocanoes Software. If you have an iPhone and iOS 16, the app may be able to read the certificates and allow you to verify and change your PIN.

What do the lights on the bottom of the Bluetooth reader indicate?

The green indicator light (second from the left) indicates power, while the blue light (third from the left) indicates Bluetooth connection. When the blue light is flashing, the reader is searching for a Bluetooth connection. When the green indicator light is flashing, the contents of the inserted smart card are being accessed. See the Smart Card Utility for iOS & iPadOS User Guide for more information.

Is there a full user guide?

See the Smart Card Utility for iOS & iPadOS User Guide.

Can I use the Twocanoes Smart Card Readers on Android?

We do not currently support Android but we are investigating support

Are there any differences between what I can access with the difference readers?

All the readers allow you to authenticate the same way and there are no differences in what you can access with the different reader.

When I tap Reader Certificates in the app, the app does not connect to the app. How do I fix this?

For the Bluetooth reader, you must give permission to use bluetooth. This is normally requested when first connecting to the reader. If you did not allow it, you can enable it in iOS Settings->Smart Card Utility. For the USB-C and Lightning readers, try disconnecting and reconnecting the reader. Force quitting the app or rebooting the iOS device may help as well.

Does the reader work with Citrix?

There is partial support for Citrix. When connecting, you will be prompted to authenticate and token file will download. Open this file and Citrix will open. Once in the Citrix app, any smart card authentication requested inside the app will not work due to lack of Smart Card reader support in the app. We are looking at resolving this issue.

Can I use the Smart Card Utility to for S/MIME encrypted email?

If email is accessed via a web interface, there is not support for S/MIME or encrypted emails. We are investigating possible solutions.

Can I use the Smart Card Utility to sign PDFs?

We do not currently support signing PDFs, but were are working with other PDF app vendors to support our readers. Stay tuned.

How do I get support? I want to talk to someone!

We want to talk to you and make sure you have the best experience with the app. Please send an email to support@twocanoes.com, use the Chat feature on our store, or use our contact form. You can also schedule a meeting.

The reader is prompting me to select a certificate often. How do I prevent this?

It is recommended to only insert a single certificate so Safari will only have a single choice and won’t prompt to select a certificate. Go into Smart Card Utility and remove all configurations, then select Reader Certificates and only insert slot 9a (PIV authentication)

Do I need to insert DoD root certificates every time I insert a certificate?

The DoD certificates profile only need to be installed once and remain installed even if the certificates or the app are removed.
