Despite all the negatives that have been reported with the US 4.3 update, I found a really useful feature. Along with the added bloatware, there is a running service called Mobeam. By itself, it does nothing. It's function is to act as an API to other apps. There are currently two apps available that utilize the service, Beep'nGo and OmniBeam. From their FAQ: "Both applications make storing managing and beaming your loyalty, gift, and membership cards easy. OmniBeam includes offers and coupons from our partner SavingStar's network of US-based retailers, and is only available to users in the US. Beep'nGo supports cards from international retailers, provides a simple and elegant user interface, and includes support for manually entered card numbers." There are many apps that store loyalty cards in a scannable format, but the problem is, most scanners can't read them because of the reflective glass on the phone. These two new apps actually send an infrared beam to the scanner, which is claimed to be read almost instantly. After transferring my cards from Key Ring to Beep'nGo, I went shopping today. I used it at three retailers and had 100% success! Even the store clerks were awed! Beep'nGo has two screens: one for loyalty cards and one for gift cards (that tracks remaining balances). You can really use it for anything with a bar code though (gym membership, transit pass, etc.), or even personalized cards without a bar code (hotel and car rental programs, etc.) by taking a picture of the card (within the app). Even though the service starts at boot, I've noticed no difference in battery life, and this thing just flat works! It is currently only available on Android 4.4 and two Galaxy devices running 4.3 - the S4 and the Note 3.
