Read UID NFC mifare 1K wristbands

[GermanParticipant]

Hello, we are using the ACR35 on iPads to be able to read a single or multiple Mifare 1K wristbands at events. We are currently using the SDK available on these forums, but have encountered a roadblock since we are not able to make the reader read from the NFC side.

We develop in Xcode, and have seen some Swift code that was able to pull this off. We are looking for a solid solution to read a single tag from inside one of our apps using Xcode.

So far we have used the NFC content library but it gives us an error when we load this content on the project. It makes a reference to a class that does not exist on the documentation: FlomioMessageTests.m – we have substituted this file for what we think is the right one which is called: MessageTests.h – but still get errors.

From the documentation:

ACR35
aR530
FloBLE
FloJack
Nfc
SDKApp

we are using the files form the NFC folder, but can’t seem to make it work. When we try to make the reader work we get this Message: nfc_card_open failed.

Any ideas? thanks!!!!

Hi German, for clarification the ACR35/FloJack driver and the Flomio SDK are two different things. The driver lets you send commands to control the reader but the Flomio SDK lets you get notified when tags are read. More details on the difference here.

Our GitHub repo contains the device drivers for low level developers that want to roll their own SDK. We had some old folders (Nfc and SDKApp) that were confusing you so I’ve just removed them. Our Flomio SDK is for high level app developers that don’t really want to spend the time debugging weird timing, threading, or data parsing issues. We currently offer our SDK via a download link here. The SDK will only work with devices that have been licensed. FloJacks purchased from our site are licensed by default but if you have an ACR35 that you’d like to activate the license for, then follow these instructions. Once activated you’ll get an invite to our Apple TestFlight program so you can test the Flomio SDK immediately with our sample app.

I hope that answers your questions and gets your development going. If you run into issues, let us know here and I’ll see how we can help.

thanks,
Richard
