RFID Reader Detector and Tilt-Sensitive RFID Tag

Step 5 Variations

This section concludes our instructable of how to build custom RFID tags. Here are a few additional tags to show the possible variations.

- Variable length of the tag antenna, and therefore also variable reading distance of the tag (Figure 1).
- Experiments with the tag size and material (Figure 2)
- Switching between the LED and an RFID chip (Figure 3)
- Light-sensitive tag: the tag is active in daylight, and inactive in darkness (Figure 4)
- Touch-sensitive: tag is active when someone touches the tag with a finger (Figure 5)
- Different material for antenna by using conductive silver ink (Figure 6)
- Stamped layout of an RFID tag antenna (Figure 7) that is in fact working!

Many other variations of RFID tags are feasible... Happy DIY!

I am new to electronics and RFID, but how does the LED get the power to light up? Thanks for the great post!

I love the touch sensor mod that you have made here. Can you provide me with a schematic for the mod? I would love to have a go at doing this myself? Pls!!

I'm thinking about explaining the alternative tag designs in another instructable; I hope I find the time soon. I'll let you know once I've created new instructions (which will also include the schematics of the circuits). These tags are, however, then a bit more difficult to build than the ones in this article.
