- Easy to Use Download the NFC Dongle App on App Store. Use your phone to read/write NFC Dongle. It is easy to set up password, lock or unlock NFC Dongle via the intuitive user interface on the App. - Strong Authentication Alternative authentication methods on the smart phone make the verification of a user’s identity easy and elevate the security level under such mechanism. - You Phone is the Key to Access Use your NFC-enabled phone and select biometric or password authentication to access NFC Dongle. It also helps reduce the operational cost from IT support when the user forgets password. - Password Control When NFC Dongle is passed onto another person, only those who know the password can operate it. Password entry is only needed in the initial reading and smart phone authentication will then be introduced to simplify the process.

Verdict
The clearest difference is in-app purchases: NFC Dongle at none against uDisk's 1. NFC Dongle also leads on update cadence (every 3 weeks vs every 2 months). uDisk's advantage is iOS requirement (11.0 vs 13.0). On price, ads and device support there is nothing between them.
