    In recent months, you may have gone out to dinner only to realize you left your COVID vaccine card at home. Luckily, the host is OK with the photo of it on your phone. In this case, it’s acceptable to show someone a picture of a card, but for other things it isn’t — an image of your driver’s license or credit card certainly won’t work. So what makes digital versions of these items more legit than a photo? To better understand the digitization of what goes into our wallets and purses, I talked to product manager Dong Min Kim, who works on the brand new Google Wallet. Google Wallet, which will be coming soon in over 40 countries, is the new digital wallet for Android and Wear OS devices…but how does it work?

    Let’s start with a basic question: What is a digital wallet?

    A digital wallet is simply an application that holds digital versions of the physical items you carry around in your actual wallet or purse. We’ve seen this shift where something you physically carry around becomes part of your smartphone before, right?

    Like..?

    Look at the camera: You used to carry around a separate item, a camera, to take photos. It was a unique device that did a specific thing. Then, thanks to improvements in computing power, hardware and image processing algorithms, engineers merged the function of the camera — taking photos — into mobile phones. So now, you don’t have to carry around both, if you don’t want to.

    Ahhh yes, I am old enough to remember attending college gatherings with my digital camera andmy flip phone.

    Ha! So think about what else you carry around: your wallet and your keys.

    So the big picture here is that digital wallets help us carry around less stuff?

    That’s certainly something we’re thinking about, but it’s more about how we can make these experiences — the ones where you need to use a camera, or in our case, items from your wallet — better. For starters, there’s security: It’s really hard for someone to take your phone and use your Google Wallet, or to take your card and add it to their own phone. Your financial institution will verify who you are before you can add a card to your phone, and you can set a screen lock so a stranger can’t access what’s on your device. And should you lose your device, you can remotely locate, lock or even wipe it from “Find My Device.”

    What else can Google Wallet do that my physical wallet can’t?

    If you saved your boarding pass for a flight to Google Wallet, it will notify you of delays and gate changes. When you head to a concert, you’ll receive a notification on your phone beforehand, reminding you of your saved tickets.

    Wallet also works with other Google apps — for instance if you’re taking the bus to see a friend and look up directions in Google Maps, your transit card and balance will show up alongside the route. If you’re running low on fare, you can tap and add more. We’ll also give you complete control over how items in your wallet are used to enable these experiences; for example, the personal information on your COVID vaccine pass is kept on your device and never shared without your permission, not even with Google.

    Plus, even if you lose your credit or debit card and you’re waiting for the replacement to show up, you can still use that card with Google Wallet because of the virtual number attached to it.

    This might be taking a step backwards, but can I pay someone from my Google Wallet? As in can I send money from a debit card, or straight from my bank account?

    That’s actually where the Google Pay app — which is available in markets like the U.S., India and Singapore — comes in. We’ll keep growing this app as a companion app where you can do more payments-focused things like send and receive money from friends or businesses, discover offers from your favorite retailers or manage your transactions.

    OK, but can I pay with my Google Wallet?

    Yes,you can still pay with the cards stored in your Google Wallet in stores where Google Pay is accepted; it’s simple and secure.

    Use payment cards in Google Wallet in stores with Google Pay, got it — but how does everything else “get” into Wallet?

    We’ve already partnered with hundreds of transit agencies, retailers, ticket providers, health agencies and airlines so they can create digital versions of their cards or tickets for Google Wallet. You can add a card or ticket directly to Wallet, or within the apps or sites of businesses we partner with, you’ll see an option to add it to Wallet. We’re working on adding more types of content for Wallet, too, like digital IDs, or office and hotel keys.

    An image of the Google Wallet app open on a Pixel phone. The app is showing a Chase Freedom Unlimited credit card, a ticket for a flight from SFO to JFK, and a Walgreens cash reward pass. In the bottom right hand corner, there is a “Add to Wallet” button.

    Developers can make almost any item into a digital pass.. Developers can use the templates we’ve created, like for boarding passes and event tickets — or they can use a generic template if it’s something more unique and we don’t have a specific solution for it yet. This invitation to developers is part of what I think makes Google Wallet interesting; it’s very open.

    What exactly do you mean by “open” exactly?

    Well, the Android platform is open — any Android developer can use and develop for Wallet. One thing that’s great about that is all these features and tools can be made available on less expensive phones, too, so it isn’t only people who can afford the most expensive, newest phones out there who can use Google Wallet. Even if a phone can’t use some features of Google Wallet, it’s possible for developers to use QR or barcodes for their content, which more devices can access.

    So working with Google Wallet is easier for developers. Any ways you’re making things easier for users?

    Plenty of them! In particular, we’re working on ways to make it easy to add objects directly from your phone too. For instance, today if you take a screenshot of your boarding pass or Covid vaccine card from an Android device, we’ll give you the option to add it directly to your Google Wallet!

    You can’t just upload a photo of your credit card and start using it…so how does a digital wallet really work? Our techspert has answers.

    A few months ago, I received a message from a friend that, I have to confess, made absolutely no sense. Rows of emoji followed by different boxes — like this 􏿿􏿿􏿿􏿿􏿿􏿿 — appeared…so I sent back a simple “huh?” Apparently she’d sent me a string of emoji that were meant to tell me about her weekend and let’s just say that it was all lost in translation.

    To find out exactly what caused our communication breakdown, I decided to ask emoji expert Jennifer Daniel.

    Why did the emoji my friend typed to me show up as 􏿿􏿿􏿿􏿿􏿿􏿿 ?

    Oy boy. No bueno. Sounds like your friend was using some of the new emoji that were released this month. (Not to rub it in but they are so good!!! There’s a salute 🫡, a face holding back tears, 🥹 and another face that’s melting 🫠!) Sadly, you’re not the only one who’s losing things in translation. For way too long, 96% of Android users couldn’t see emoji released the year they debuted.

    And it isn’t just an Android problem: Despite being one of the earliest platforms to include emoji, Gmail received its first emoji update since 2016 last year! (You read that right: Two-thousand-sixteen!) This often resulted in skin toned and gendered emoji appearing broken.

    A few examples of „broken“ skin tone and gendered emoji.

    What!? Why?

    Yeah, strong agree. Historically, emoji have been at the mercy of operating system updates. New OS? New emoji. If you didn’t update your device, it meant that when new emoji were released, they would display as those black boxes you saw, which are referred to as a “tofu.” It gets worse: What if your phone doesn’t offer OS updates? Well, you’d have to buy a newer phone. Maybe that’d be worth it so you can use the new finger heart emoji (🫰)???

    Emoji are fundamental to digital communication. Meanwhile, there is a very real economic divide between people who can afford to get a new phone every year (or who can afford a fancy phone that generously updates the OS) and everyone else in the world. That is absurd and I personally hate it. Now for the good news: Check your phone, I bet you can see the emoji from your friend’s message today.

    Whaaaaat! You’re right. Why can I see them now but I couldn’t a few months ago?

    Well, this year Google finally decoupled emoji updates from operating system updates. That means YOU get an emoji and YOU get an emoji and YOU get an emoji!

    Examples of emoji

    What does “decoupled” emoji updates mean?

    It basically means emoji can be updated on your phone or your computer without you updating your operating system. As of this month, all apps that use Appcompat (a tool that enables Android apps to be compatible with several Android versions)will automatically get the latest and greatest emoji so you can send and receive emoji even if you don’t have the newest phone. And this will work across Google: All 3,366 emoji will now appear in Gmail, on Chrome OS and lots of other places when people send them to you. Apps that make their own emoji rather than defaulting on the operating system may find themselves falling behind as taking on the responsibility of maintaining and distributing emoji is a lot of work. This is why we’re so thrilled to see Google rely on Noto Emoji so everyone can get the latest emoji quickly.

    Since you mentioned Gmail being an early emoji adopter, it makes me wonder…how old are emoji? Where do they come from?

    A volunteer-based organization called the Unicode Consortium digitizes the world’s languages. They’re the reason why when you send Hindi from one computer the computer on the other end can render it in Hindi. In their mission to ensure different platforms and operating systems can work together, they standardize the underlying technology that Google, Apple, Twitter and others use to render their emoji fonts.

    You see, emoji are a font. That’s right. A font. I know. They look like tiny pictures but they operate the same way any other letter of the alphabet does when it enters our digital realm.

    Like the letter A (U+0041) or the letter अ (U+0905), each emoji is assigned a code point (for instance, 😤 is U+1F624) by the Unicode Consortium. (Some emoji contain multiple code points — I’m generalizing a bit! Don’t tell the Unicode Consortium.) Point being: Emoji are a font and like fonts, some emoji on iPhones look different than they do on Pixel phones.

    A variety of the new emoji designs that are now visible across Google products including Gmail, Google Chat, YouTube Live Chat and Chrome OS.

    So, the Unicode Consortium makes fonts?

    No, they manage a universal character encoding set that written languages map to. Google’s Noto project is a global font project to support those existing scripts and languages. Google uses Noto Emoji and provides resources to ensure your emoji render on Android and in desktop environments including metadata like iconography and shortcodes too! All Google chat products now support this.

    We’re also working on ways for you to download or embed Noto Emoji into your website of choice via fonts.google.com. So, stay tuned 😉.

    Emoji are a font. Black boxes are tofus. The more you know! I guess I have one final question: Now that I can send (and see!) the melting face emoji, will it look identical no matter who I send it to?

    Well, every emoji font has its own flavor. Some of these design variations are minor and you might not even notice them. With others, primarily the smilies (😆🤣🥲), the details really matter — people are hardwired to read micro-expressions! The last thing anyone wants is an emoji you see as a smile and someone else sees as a downward smirk — it can ruin friendships! Fortunately, over the past three years designs have converged, so there’s less chance of being misunderstood 🌈.

    Ever wondered why emoji don’t always…work? Google’s resident emoji expert Jennifer Daniel has the answers. And, even a fix.
