I’m using my iPhone to scan in a complex 2D barcode. Problem is, the iPhone camera doesn’t do so well at very close distances (less than 3 inches).

I was wondering if there were a way I could affix a Bluetooth low energy “sticker” to a piece of paper. The idea being instead of using the camera to scan a 2D barcode, I could just put my iPhone near the paper and “scan” it.

I’m extremely new to Bluetooth tech, so it’s quite possible that what I’m asking for is completely ridiculous. Please forgive me, if that is the case.

    Unlike NFC, Bluetooth Low-Energy devices need a power source, so it’s imposible to just “print” them. They need a BLE chip and a battery to operate. So while you could use BLE same way you use NFC (proximity-based actions), you won’t be able to do it with just a sticker.
