Calling Card

Tap an RFID card on a Tessel RFID reader to send a text over Twilio to any phone.

You need

• Tessel + RFID Module + RFID card (one comes with the module)
• A phone (to receive texts)

Setting up

1. Set up your Twilio account (it's free!)
2. Install your Tessel and plug the reader into ports A & B
3. Clone this repo
4. Set up your config.json file based on the example-config.json file
5. Run npm install to install Node dependencies
6. Connect Tessel to the internet
7. Run the code on Tessel: tessel run index.js
8. When the console logs that the reader is ready, tap a card to receive a text!

Future work

This is a work in progress; it would be much more useful to create a lookup for different UIDs, and associate specific RFID cards with specific people.

Use Cases

• "I'm home" text to family members
• Someone came to visit, but you weren't there (think Victorian calling cards)
• Very fast check-ins at locations with associated RFID cards (e.g. if you could register a transit card with Foursquare to check in at locations)
• Tool checkout– tap to text someone that you're borrowing their thing
