Passbook

Lemon Wallet for iPhone is basically a virtual wallet similar to Passbook but picks up where it lacks. For instance, you can easily create Passbook cards with Lemon Wallet for any credit card, identification card, or rewards card regardless of whether or not that actual merchant supports Passbook. Lemon Wallet also has add-on paid features that allow you to track transactions and report a lost or stolen wallet for easy card replacement options.

It's still a pretty big deal when iOS apps are released with Passbook support, especially outside of the U.S. Anyone flying down under will be pleased to know that Australian airline, Qantas, has released their brand new iOS app which indeed does have Passbook support.

Passbook enabled apps in the UK are still a rarity, but we can now add another one to the list. UK based low-cost airline, Easyjet, has updated their iPhone app bringing with it mobile boarding passes and Passbook support. This ties in with a new Easyjet initiative whereby all their airport check-in facilities are to be closed, and replaced by online check-in methods.

Passbook can be an incredibly useful tool for storing all kinds of things from boarding passes to loyalty cards to gift cards and more. Unfortunately, the App Store doesn't make it so easy to find apps that are Passbook compatible. While there is a list, it isn't updated very frequently and misses a lot of hidden gems that ourselves and many of our readers have found over the past few months.

So if you're itching to add more items to your Passbook and find an actual use for it, here are our favorites:

Instead of media and markets continuously hounding Apple about "what's next?!", there's a case to be made that Apple has already announced several services that could do with a little -- or a lot -- of their attention. It might not be as magical or revolutionary as a fresh name on a big slide, but making what's already here work better could also increase the value of Apple's platform as a whole. At least that's what Joe Cieplinski thinks:

If you use Passbook frequently on your iPhone, you may have noticed that certain passes use your location in order to give you easy access on your lock screen to a specific pass when you're within the vicinity. Some of those passes may contain personal information or allow for someone to charge an item to a gift card or account.

If you'd like to prevent unauthorized access to your passes, you can easily do so within Passbook. Follow along and we'll show you how.

Passbook for iPhone may be a great tool for managing boarding passes, reward cards, and more, but it can also be a drain on battery. Since Passbook continuously checks your location to see if you're in range of somewhere you may want to use one of your passes, it can significantly decrease your battery life.

While it's a convenient feature, if you're finding your battery life is suffering, you can disable location services to lessen the strain on your battery.

If you've got a passcode set on your iPhone, Siri and Passbook will still work by default on your lock screen. This means that anyone who wants to talk to Siri or use one of your passes will still be able to. While it's convenient, it can be a bit unsafe. If you prefer having to use your passcode in order to access them, you can do so easily with a simple settings change.

Here's how.
