Quirky is a design shop that uses ideas from a crowd of contributors and influencers to create new products. In the past, it's come up with some incredibly useful Apple-related accessories like the US$12.99 Power Curl, which has made its inventor almost $80,000 in royalties. Now the company is evaluating a new idea -- a touchscreen stylus called the Cipher (expected price $4) that fits in your wallet like a credit card.

That's because it is a credit card, made with a capacitive material that acts just like your finger or a more traditional stylus. When you want to draw on your iPhone or iPad, you grab the Cipher from your wallet and go to town. There's less chance of losing the Cipher like a regular stylus, and the fact that it will be sold in a 2-pack means you can always have at least one in your wallet.

At this point, Cipher's still in the product evaluation phase, but keep your eyes open for the clever flat stylus in the near future.
