The FloJack is a pocket-sized NFC reader, and writer, for Apple mobile devices. It brings the revolutionary power of NFC to the iPad, the iPod Touch, and the iPhone. Now, Apple mobile devices can start touching the real world.
We’re also happy to announce that the FloJack has been made to work with Android devices as well!! So if your Android device doesn’t come with a built-in NFC hardware, don’t worry.. FloJack’s got your back.
The FloJack is compatible with iPhone 4, iPhone 4S, iPhone 5, iPhone 5s, iPhone6, and iPhone6+ as well as the 4th and 5th generation iPod Touch. It works on all iPads and Samsung Galaxy tablets. For more details, check out FloJack Specification v2.0.
The FloJack has come a long way. The first prototype was the size of a lunchbox and weighed a ton. So we shrunk it down 2,000% and made it pocket size – small and light. We’ve built hundreds of FloJacks and they work great! To test out that your FloJack is working correctly, follow these steps:
1) Launch the ACS MobileMate App and connect the ACR35 to the audio jack of your iOS device. Immediately a green LED on the ACR35 should light up. If not your iOS device volume is low or the ACR35 needs to be charged.
2) Select “Explore Contactless Card” from the menu options.
3) Place a tag on the surface of the ACR35 where it has the “NFC” logo (both sides of device work)
4) Tap the “Answer-to-Reset (ATR)” field at the top of the app window. This will pull the tag into reset and get some basic protocol information. This is what I get when reading one of our NFC stickers:
Answer-To-Reset (ATR) Init| T0| TD1| TD2| T1| Tk| Len | RID | Std | Card | RFU | TCK Hdr | | | | | | | | | Name | | 3B | 8F| 80 | 01 | 80| 4F| 0C | A0 00 00 03 06| 03 | 00 03| 00 00 00 00| 68
Worth studying are the following fields:
Len = 0C // 12 bytes of config data RID = A0 00 00 03 06 // Registered App Provider Identifier: PC/SC Workgroup Std = 03 // Standard format: ISO14443A, Part3 Card Name = 00 03 // Mifare Ultralight
Other possibilities for cards include:
00 01 // Mifare 1K 00 02 // Mifare 4k 00 26 // Mifare Mini F0 04 // Topaz and Jewel F0 11 // Felica 212k F0 12 // Felica 424k
5) Now that you know what card name you have, you can construct the APDU to request it’s UUID. The Mifare Ultralight has a 7 byte UUID so the Get UID Format should be:
Command | Class | INS | P1 | P2 | Le Get Data | FF | CA | 00 | 00 | 00
Response | UID | SW1 | SW2 Result | 04 CC 2F DA C4 29 80 | 90 | 00 // this is my UID
6) You can then validate you’ve read the right UUID by read the same tag with an Android NFC phone running the NFC TagInfo App and reviewing the Tag Information->UID field value.
We’re also excited to announce the FloJack Open SDK. Now, it’s easy for developers to add NFC to their iOS and Android apps. And together with the Flomio Cloud Infrastructure – developers can power NFC experiences across all devices.
The SDK includes:
- FloJack Firmware Interface
- FloJack OS Helpers
- Docs, Sample Apps, Tutorials, etc
- Get it here: iOS or Android
It’s super easy to get started – drop our static library into your development environment and you’re ready to go. We handle the low level NFC protocols, audio sessions, and all the other hard stuff! The SDK also provides seamless integration with the Flomio experience engine allowing you to bridge the digital and physical worlds with experiences like ‘tap to like’, ‘tap to check-in’, and more.
