NFC in 2011: Who's Building Your Mobile Wallet?

Av
We are into this field, with all arms and feet! I tell you more later.

A post from ReadWriteWeb by Sarah Perez has the whole story. Here is a part:

NFC, or near field communication, is an emerging technology you'll start hearing more about in the coming months. In this introductory series to understanding NFC, we're examining the state of the industry from end-to-end, and we'll focus on what the technology is, who's implementing NFC-enabled solutions and how those solutions will work.
One of the future use cases for NFC is to create a "mobile wallet" of sorts - a comprehensive service that houses everything from bank cards to coupons, all managed, accessed and delivered via your mobile phone. But what companies are building mobile wallet solutions today and whose mobile wallet will you use?

This is the second post in a series on NFC here on ReadWriteMobile which will serve to get you up to speed on what NFC is, what notable developments are underway and what commercial programs using NFC will arrive this year. You can follow this series by clicking the tag  (or bookmarking the tag) "NFC 2011."
Before we could begin talking about NFC developments, advances and upcoming commercial programs in specific, we first had to get you up to speed with what exactly NFC is. The first post in the series is the best starting point for those unfamiliar with the technology. In the post below, we'll examine the different types of mobile wallet initiatives that will use NFC.

How Can a Phone Replace a Wallet?

CaseforiPhone3GSfront
When you think about a technology designed to replace your actual wallet - you know, the beat up leather-bound bill holder containing cash, credit and debit cards, paper receipts, coupons and discount cards  - you begin to realize what a complex undertaking it is for any one company to deliver a complete solution.
A credit card company like Visa may team up with your bank to offer you a way to use your mobile phone as a replacement for a single plastic credit card, but it's only one piece of the pie. What about the coupons? What about your loyalty cards? What about the rest of your credit and debit cards from other banks?
At present, Apple, Google and other mobile platform providers are likely working on a comprehensive mobile wallet solution for consumers, but they lack experience in some areas where financial services companies excel: providing customer support for issues like the proper handling of chargebacks, understanding the relevant regulations that apply to the industry, implementing the necessary level of security that must be involved when processing transactions from a host of merchants and hundreds of thousands of customers through a large worldwide network built for transactions, and other concerns.
Given these challenges, it's not a sure thing that your preferred mobile wallet provider will be the one Google or Apple or another mobile platform provider creates; it may be a service from your mobile carrier (for example, here in the U.S., Verizon, Sprint, T-Mobile or AT&T).
A third possibility is that your bank itself ships some type of complete mobile wallet system as a part of their mobile banking/mobile payments product. In this mobile wallet, other third-party services could complement the bank-provided, NFC-enabled debit and credit "cards" you use on your NFC-enabled mobile phone.  (Not actual plastic credit cards, but digital ones, stored on your device).
There's no real answer to the question about who will be the dominant mobile wallet provider, not only because these services have not yet launched (or are just now doing so) but because when they inevitably do, there's no way to foretell which service consumers will actually prefer.
To begin our overview of mobile wallet, we're going to look at three different types of players, which we will break down into three categories we'll call the apps vs. the operators vs. the banks. But first, let's examine what a mobile wallet actually is.

But What Is a Mobile Wallet?

Predicates in Core Data

Av
Database programming is all about filtering and sorting tables linked to each other. According to the book Core Data , «Core Data is Apple’s object graph management and persistency framework for iOS, OS X, watchOS, and tvOS.» In a sense, predicates are an object version of the WHERE clause in SQL. Just like NSFetchRequest represent the FROM clause in SQL. I never have had problems with WHERE and FROM in SQL, but the predicate format strings in Core Data has been quite a struggle for me. I don’t think the struggle is only my fault. Predicates should clearly be thought, at least to me, as a method of writing WHERE clauses. Here is some notes from tutplus’ Core Data and Swift: Relationships and More Fetching : let predicate = NSPredicate(format: "%K == %@", "last", "Doe") The predicate format string uses %K (K stands for Key) for the property name and %@ for the value. let predicate = NSPredicate(format: "%K >= %i", ...

How To Disable Google’s Personalization Of Search Results

Do you want to know what the rest of the world gets as answer for their search, instead of what Google thinks you may want to see? I do, therefore the post from MakeUseOf.com by Ann Smarty did catch my interest. She explains it well, both for one-time use and how to change your firefox and chrome browser, and I just copy the one-time part: 2. Disable Google Personalization: One-Time (Browser Independent) Again, you may like the feature and the fact that Google tries to show you what you really want (your favorite sites or sites you are more likely to like on top), but in some cases you will want to see “real” results (for example, to check how your own website is doing). In this case, what you need to do is manually modify the search query URL path: just add this parameter: pws=0 The ‘pws=0′ parameter removes the search personalization: If you don’t want to add the parameter manually, use this browser bookmarklet (courtesy of  Google System Blog ): Turn off Google perso...
