In the research article about the ongoing DM3005 project I’ve already explained the idea about “Remind me on…” in general and other similar projects. In this article I want to describe more the feasibility of the project.

Technology behind the project

The project uses RFID chips and readers to communicate between the bag and the items. For covering the whole size of a bag, we need a high range for our RFID Reader to read out the Transponders. The smallest frequency we need would be high frequency ranges (HF, 3–30 MHz), commonly used here is the 13,56 MHz frequency. With this, we should get a range of 5cm to 10cm, which is sufficient for test purposes.

The transponders should be placed on the items, so they need to be tiny and thin. I’ve found a RFID Sticker:

  • - Price per sticker: 1,59 EUR
  • - Diameter: 30 mm
  • - Frequency: 13,56 Mhz

For the RFID Reader I’ve found one which sounds convenient:

Normally the connection to the smartphone would be via Bluetooth, but for testing purpose I would use the arduino.
