[Tech blog] A weekend mini-project, EM02 reader links up wearables and controller

Just a simple DIY quick project, showing how to make a home automation or access control, the EM02 reads any bluetooth low power gadgets such as Mi-wristand, or Jawbone or Fitbit, or similar.

The SD-card image can be provided upon request, it provides a website for simple configuration, save the low power gadgets's ID timestamp, in SD card, and control the relay. 

What would be the software looks like? to-be-continued in next blog, stay tune.

Bill of material:

Raspberry Pi 2nd-gen, Real time clock, Piface controller 4-relay 4 I/O, 8G Sandisk card with SDK program	1 set

USB power for Pi	1pc
USB to Serial Port	1pc
USB to DC2.1 jack	1pc
Empress EM02-SP reader (serial port)	1pc
Sport wearable gadgets, or 2.4G low power transponders, Mi-wristband, Hussar NT02 transponder, jawbone UP24, Fitbit Flex, etc.	-

Preview on new features for EM02 latest firmware, BTLE added.

Apart from Empress series transponder such as Hussar/Garrison/Tempcorder series, now Empress EM02 readers can also gather the beacon signal from BTLE devices, especially useful for scanning IDs from wearables such as Fitbit, Jawbone, etc.

Empress EM02 is a FCC CE certified reader, has long been used as data gatherer for telemetry business applications together with Empress series transponders. With the latest upgrade, by simply switching setting by software command, it can read bluetooth device's ID, meaning the reader can now work alone in many other business applications. This reader can be used as gateway for Bluetooth smart devices (BT4.0 or above), which is popular in smartwatch, wearable, health activity recorder, mobile phone apps, etc.

BT4.0 or BTLE USB dongles are common and they can do the same, they are best for small scale development and demo test. However, this EM02 reader provides more options in project implementation, in terms of choice of extendable antenna and network connectivity.

This EM02 is also perfect for projects which requires reading proprietary devices and BTLE devices at the same time (DUAL mode), for example, reading meter readings (proprietary) and staff ID (BTLE) at the same time. See the video for live explanation.

Raspberry Pi will change the game in RFID industry [Insight]

Anyone has spent some time on googling "RFID" will soon realise comprehending RFID-product should earn you a doctorate degree. The toughest part is the "RF" in this 4-character word, it involves the selection of right RF reader and tag, system design and installation, not to mention the expensive middle-ware software and application software part. These factors lead to long sales and project cycle, eventually unsuccessful user experience.

HK-RFID has over 10 years of RFID design and deployment experience and we believe Raspberry Pi might be the game changing solution, bringing extra value in the whole RFID value-chain. 

Raspberry Pi is a low-cost mini-computer, with a proper program installed, it will be capable to handle basic RFID reader setting, data processing and provide data output. The user-skills required should be as simple as typical household WiFi router setting. 

We are developing a web-interface on Raspberry Pi (Project code: IMPRESS), so user-friendly that user doesn't require any programming skill or RFID knowledge. One single set of Raspberry Pi and RFID reader would be enough to cope with instant DEMO request, and small-scale business applications such as Attendance, Inventory Listing, Media trigger, etc. All it takes is just mapping IDs to what your names and actions, with a few clicks on a web-interface. 

Automatic data delivery to server by Raspberry Pi, in a customised format, would make system integration so easy that the programmer no need to study the long API document or call any library. They just need to set the network setting and all data will be auto-update into database. 

HK-RFID is capable of integrating Raspberry Pi into any of its RFID reader in their product series, as one single product. However, doing so may add up extra-cost to the product and bringing less value because users have fewer upgrade options. 

Raspberry Pi, as a part of RFID system, will accelerate the wide-use of RFID, including the evolving Bluetooth low energy (or BLE, BT4.0, ibeacon) and near-field-communication (NFC) technologies . The same platform can apply to any BLE dongle to perform more network or database related function.

Apps-in-a-Box : Raspberry Pi x RFID [Beta] [Lab]

We are so excited to introduce you all an innovative approach to use RFID reader products, by connecting Raspberry Pi to RFID readers. We are developing a tentative project named: IMPRESS platform, which is a web-service on Raspberry Pi, talking with Empress RFID readers, and others.

The basic idea is running your applications on Raspberry Pi just like any PC, and let it control a or multiple brainless RFID readers. We offer a web-interface just like household WiFi router for reader settings, as well as basic business applications.

If you are not sure what Raspberry Pi is, please visit following reference link; What is Raspberry Pi?

Video is on the way, but first please read the details explained in Q&A manner; 

Q: Why connect Raspberry Pi to RFID readers?

A: By doing so, you can have

• much cheaper "self-maintained mini-computer" (less than USD 40) that talks with your RFID readers, without any skill-set to handle RFID's protocol and calling APIs, etc.
• a website to configure the readers and do a lot more business applications;
• a lot more choices on connectivity, such as, LAN, WiFi, Bluetooth, USB, SD-Card, Video ouput HDMI, etc.; instead of ordering expensive RFID reader options. 

Q: What can Raspberry Pi do with the data get from RFID readers?

A: Raspberry Pi can 

1) Auto record and deliver to server, send email 

2) Send email or trigger outputs, alarms or camera, etc

3) Process more logic such as record the first/last seen ID, their time and duration, and missing IDs

4) Mapping meaningless long ID with more meaningful names, such as student names, employee names, etc., may be export a report.

Q: What kind of readers will be support?

A: Our IMPRESS-Preloaded Raspberry Pi will support

1. Empress 2.4GHz Active RFID readers from HK-RFID [primarily]
2. Bluetooth Low Energy (iBeacon) readers
3. NFC readers
4. Other client requested RFID equipment

Q: What kind of applications or services will offer on this IMPRESS web platform?

A: Apart from basic setting of readers, we will offer several most popular RFID applications, depends on the license purchased from users

1. Attendance
2. Prohibited zone (access control)
3. Signage or media-content trigger
4. EAS anti-theft
5. Sensor data
6. Inventory list

Q: How to make it work?

A: You just need to 

1. Purchase the IMPRESS-SDK kit which include a Raspberry Pi and a Empress 2.4GHz Active RFID-kit from HK-RFID, 
2. Enjoy the unboxing, connect up Raspberry Pi with any HDMI display and reader, configure the network settings on a browser
3. Set your business applications and there you go

Q: How many readers each Raspberry Pi can support?

A: ONE

Q: When will it be available?

A: 2014 Fall, please contact us if you want to follow our development progress or Pre-order. We welcome any comment and partnership, or proposal of co-development.
