Giving RFID a Slice of Raspberry Pi
Yesterday the Raspberry Pi foundation released their microcomputer for the everyman. It’s the size of a credit card and costs $35. You plug it into a keyboard and TV and have a mini-ARM based PC that can do much of what your desktop can do. It runs a Linux OS.
This is what it looks like and here are the specs:
- Broadcom BCM2835 700MHz ARM1176JZFS processor with FPU and Videocore 4 GPU
- GPU provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode
- GPU is capable of 1Gpixel/s, 1.5Gtexel/s or 24GFLOPs with texture filtering and DMA infrastructure
- 256MB RAM
- Boots from SD card, running the Fedora version of Linux
- 10/100 BaseT Ethernet socket
- HDMI socket
- USB 2.0 socket
- RCA video socket
- SD card socket
- Powered from microUSB socket
- 3.5mm audio out jack
- Header footprint for camera connection
- Size: 85.6 x 53.98 x 17mm
While this is aimed largely at the education market to get kids excited about programming, the implications go well beyond tinkering and DIY projects. What Raspberry pi has done is bring a full on, real-deal computer to the market for 35 bucks. If this type of technology exists, and the creativity to make it happen there is no reason that some smart RFID guys (or gals) couldn’t bring an RFID device to market that works at long range, with I/O functionality for around $100.
No matter what anyone tells you tags are cheap enough, the hurdle is the cost of the readers.When there is a $100 RFID reader the world will become truly connected and we can enable an Internet of things.
RFID in Hospitals will revolutionize health care. Asset tracking will become a thing of the past because everything will be visible. Social media will become frictionless through automation. And the world will will have an Internet that doesn't stop at laptops and mobile phones but extends into the real world. Take a slice of Raspberry pi and go make yourself a cheap reader and change the world!
