Bluetooth HF RFID Reader PCB and Enclosure design finished

After some Bluetooth RFID Reader prototypes I created a new board which is designed to fit into an enclosure which will be printed by a 3D print service. The Reader can be connected to iOS Devices and sends the UID of a MIFARE Tag as text string into any iOS app which is capable of handling texts.

A tactile switch is added to the reader as well, in order to unhide/hide the on board keyboard on an iPhone or iPod Touch.

The PCB is already in production and will arrive for assembly in a week. During this time I will spend some effort in designing the enclosure.

More details about this reader will be published in the Hardware Projects section soon.

    Dear Dr. Michael Kroll!
    I’d like to develop an iOS App which can communicate with a hardware trough bluetooth. And I’d like to design a hardware too.
    May I ask you, this HF RFID Reader is made under Apple MFi program? Or it uses the BlueGiga BLE112 Bluetooth 4.0 module (you mentioned it in a previous post), and this module can connect to iOS device?
    I read that, from iOS5 there is a corebluetooth API in the SDK, which allows to connect with BluetootH 4.0 devices. The only thing I don’t know, can I build a hardware for that?
    Thank you for your help!

      Hello Peter,
      the HF RFID Reader project is not made under the MFi program. The Reader connects as Bluetooth keyboard to an iOS device and sends the Tag UID as simple text string to the device.
      I received to new PCBs I ordered about 10 days ago and aIready build one reader so far which runs after fixing two design faults in the schematic. Moreover I ordered two plastic enclosure parts I designed as well. Now I’m waiting for the top part, which is the reason for not writing another blog post since I want to describe all three parts, the PCB, the bottom and top enclosure and how they fit together. After I received the bottom part I must say it fits perfectly, but I will do a v1.1 of the PCB which is already finished and a v1.1 of the enclosure as well.

      Concerning the BLE I already created two small BLE112 Development modules which looks like breakout boards for easier development of BLE hardware. I’m doing some progress in developing an RFID Reader using BLE, but it would be a pleasure to work in a team on this project.

      I did an initial iOS app which can read device services and characteristics from the “Texas Instruments CC2540 Mini Development Kit” Keyfob but it is in a very early state.
      I’ll write an update concerning the reader as soon as I received the top enclosure part from the 3D printing service.

      Thank you very much for your interest in my project,
      Michael.

    helloI am an indonesiaindonesia also has e-Passporti have three qtisueon to you::first, would you like to explain in the text by reply my comment about how to improve the shield????? because my english is not too goodsecond, would you like to see indonesian e-Passport??and, is that chip of indonesian e-Passport can be read like your video (hack)???third, would you like to give information to me, how can i make a simple reader machine to read RFID ???? thank you
