USB On-The-Go (OTG) adapter can be used to connect USB-A security keys to USB micro or USB-C smartphones.

A lot of different form factors are supported by the Hardware Security SDK.

Does it Support External NFC/Smartcard Reader?

In theory, the SDK can be configured to use external NFC/smartcard readers connected via USB to the phone. As this is a niche use case, only a small number of readers are officially supported. Please contact us, if you plan to use this feature.

Tested readers:

ACS ACR1252 (contactless, recommended)
SCM Microsystems Inc. SCR 3310 (contact)
Gemalto Prox DU (contact + contactless)
