Everyone can be forgetful every now and then, but you'll never forget your keys, cell phone, wallet, or virtually anything else at home again with the Deja Vu RFID Purse. In the simplest terms, the cute blue tote tells you when you've forgotten to put items in your purse.

The Deja Vu RFID Purse was created by Heidi Chen and Nicole Tariverdian from the Massachusetts Institute of Technology. The bag uses a Lilypad Arduino technological system that senses when something is missing from the inside of it. There are five spaces to put whatever you need in the Deja Vu RFID Purse and by using RFID tags in each space, the purse will detect which spot is empty.

You'll be made aware of which items are missing using an LED notification system.

Keys? Check. Phone? Check. Anything else you may need? Check, check and check.
