The Amazon accessibility-enhanced website is an excellent place to begin your online shopping adventure, but you will naturally want to make purchases from other online retailers as well. These days most retailers offer online sales, and even if a site has accessibility glitches, you can usually power your way through them.
Most online merchants accept both credit and debit cards. With all the news about merchants having their data hacked and stolen, however, you may be a bit reluctant to enter this information online. The truth of the matter is that you are at greater risk of having your financial data compromised when you hand your credit card to a waiter at a restaurant. Also, most credit card providers will waive any fraudulent charges you report in a timely manner. So it’s a good idea to review your credit card statements at least monthly (see the next section for more information).
Also, check with your credit card company to see if they offer one-time account numbers that cannot be hacked because they can only be used once. Other banks offer account numbers that can only be used to pay for items from a single online merchant and will be denied for payment anywhere else.
Another solution is to set up an account with one of the following payment systems.
PayPal
PayPal is the world’s largest online payment service. They take security seriously, and they have staff working exclusively on accessibility.
Basically, PayPal is a service that sits between your bank and credit card accounts and merchants. Sign up for an account, and you will be prompted to enter your card information. You can also enter your checking account information. Providing this information makes it very easy to send cash to friends and family, or to transfer money back and forth between your accounts and PayPal. Choose which credit card or bank account you wish PayPal to use for any one transaction, or set a default option, and when you make a purchase PayPal will charge that account and pay the merchant, without passing through any of your personal financial information.
Most major online merchants accept PayPal as a payment option. But where PayPal truly shines is when you are making a purchase from a smaller merchant, where they do not have the resources to keep your financial data secure from hackers.
The PayPal website is extremely accessible. When you choose PayPal as a payment method, your browser is redirected to the PayPal site. Log in, confirm the payment on a completely accessible web form, and you are done. Your purchase has been completed, and the merchant does not get to even see your credit card or bank account information.
The PayPal apps for Android and iOS are also quite accessible. Many national chains, such as Dollar General and Home Depot, now accept PayPal at their registers. Enable the app to access your phone’s location services and you can see a complete list of nearby restaurants, beauty salons, and other local merchants that accept PayPal.
Google Wallet
![Best mac terminal app Best mac terminal app](/uploads/1/3/3/9/133940898/405875080.gif)
If you are an Android user, you will need to set up a Google Wallet account and add a credit card before you can purchase paid apps, books, music or videos from Google Play. Many web stores also allow you to “Pay with Google,” which works similarly to PayPal. You can also use the Google Wallet app for Android oriOS to store and use all of your merchant loyalty cards, which means you won’t have to fumble through your wallet looking for a loyalty card you can’t read—and Google Wallet can also access your location and display any number of nearby special deals and offers.
Accessible In-Store Payments with Tap to Pay
Both Google Android and Apple iOS offer the ability to make in-store payments from your choice of debit or credit card accounts without swiping a physical card. Instead you merely tap your phone to the point-of-sale terminal. Google Wallet users then enter their app PIN; Apple Pay users touch a finger to their phone’s Touch ID.
Tap-to-pay services are only available on mobile devices that include a near field communication (NFC) chip and antenna. Most newer Android devices include NFC, but only the latest models of iPhones (6, 6 Plus, and later) and the iPad Air 2, include NFC. Best windows 10 productivity apps.
Google Wallet, which uses MasterCard PAYPASS, has a significant head start on Apple Pay. PAYPASS is accepted by tens of thousands of merchants around the world. Apple Pay is just getting started but growing fast.
Regardless of whether you use Google Wallet or Apple Pay, if you have a visual impairment, these apps are exciting developments that will significantly enhance your ability to shop safely and independently. To demonstrate how, let’s review a typical checkout experience:
- At the register, the first thing you need to do is find the credit or debit card you wish to use. If you have several, this can be difficult. Using an app, you can accessibly scroll your list of cards and select the one you want.
- Once the cashier has totaled your purchases, you can't check to make sure the prices are correct, and you must rely on the cashier to tell you the total, which you cannot otherwise confirm without a sighted companion. With an app, you can see a list of the items purchased and their prices, and the amount you see on your device’s screen is the amount you will be charged and pay.
- Now it’s time to swipe your card. It may take multiple attempts to get the card positioned in the correct orientation, and then you need to enter your PIN. Most point-of-sale terminals do not have touch guides that allow you to enter your PIN independently. You have no choice but to announce your PIN to the cashier or shopping companion—without knowing who else is overhearing you and taking note. Even if you can manage to enter the digits yourself, you are still left wondering if someone is watching over your shoulder. Using a tap-to-pay app, all you need to do is tap your phone to the terminal, then enter your PIN accessibly on your Android phone, or touch a finger to your iPhone’s Touch ID.
- The cashier tucks your receipt into the bag, and unless you scan it using OCR, that is the last you see of your purchase record. With tap-to-pay you can access a running list of your purchases and money spent.
Did you spend more than you intended? Possibly more than you have in your bank account? It’s time to check your bank or credit card balance. In the next section we will show you how to do this accessibly on both your computer and your mobile device.
Every Mac is built with assistive technologies to support people who are blind or have low vision. The VoiceOver screen reader describes exactly what’s happening on your screen. Hover Text lets you instantly magnify a selection of text. And Display Accommodations support color blindness and other vision needs.
Hover TextGet a quick size boost of what you’re reading.
Hover Text makes it easier to view text on your display. If a paragraph, caption, or headline is too small to read, just hover over it with your cursor and press Command. You’ll get a dedicated window with a large, high-resolution version of your selection. You can even choose the fonts and colors that work best for you.
VoiceOverHear what’s happening on your screen.
VoiceOver does more than tell you what’s happening on your Mac. It helps you make things happen. It gives you auditory descriptions of each onscreen element and provides helpful hints along the way — whether you prefer using gestures, a keyboard, or a braille display. And it supports more than 35 languages, including multiple voice options.
VoiceOverIntegrated throughout macOS and every built-in app.
VoiceOver is unique because it’s not a standalone screen reader. It’s deeply integrated in macOS and all the built-in apps on Mac. And as developers update their apps to take advantage of the accessibility interfaces provided by Apple, their apps can start working with VoiceOver right away.
VoiceOverImproved PDF, web, and messages navigation.
We’ve refined VoiceOver to make it easier to navigate PDFs, websites, and messages. In Safari, improved conformance with HTML5 accessibility standards allows for more consistent navigation of websites. VoiceOver is now better at reading aloud tagged PDFs and email messages. If you start reading a website in a different language, VoiceOver can switch to the voice for that language automatically.¹ And you can add custom commands and workflows to your MacBook Pro with Touch Bar.
Audio DescriptionsHear the details in every scene.
Watch movies with detailed audio descriptions of every scene on your Mac. Movies with audio descriptions are displayed with the AD icon in the iTunes Store.
VoiceOverNavigate VoiceOver with simple gestures.
You can control VoiceOver using many of the same gestures you use with iOS. Touch the trackpad to hear a description of the item under your finger, drag to hear items continuously, and flick to move to the next item. Enable the VoiceOver Trackpad Commander, and the trackpad surface will represent the current window or document, so you can navigate quickly to any corner or edge with a tap.
VoiceOverA virtual controller with customizable commands.
VoiceOver features a virtual control called the rotor. Turning the rotor — by rotating two fingers on the trackpad as if you were turning an actual dial — lets you access an array of fully customizable commands. Use it to browse web pages more efficiently and intuitively. The rotor lists common elements like “headings,” “links,” and “images,” and lets you navigate directly to the element of your choosing.
VoiceOverPlug-and-play support for braille displays.
VoiceOver is the first screen reader to provide plug-and-play support for refreshable braille displays. Plug in or sync one of over 100 compatible displays, supporting more than 80 international tables, and the VoiceOver description is presented to you in braille. You can edit seamlessly in Grade 2 Braille, viewing your edits in the context of the actual line of text. Optimized for fast braille typists, VoiceOver makes working in braille easy and efficient. Converting between braille and text happens automatically so you see only Grade 2 Braille. And for sighted users who sit alongside you, there’s an onscreen braille panel that displays both braille and plain-text versions of the descriptions spoken by VoiceOver.
Dark ModeWorking hard gets easier on the eyes.
Dark Mode transforms the desktop and built-in apps with a dark color scheme that helps you focus on your work.2 The fine points of your content take center screen as toolbars and menus recede into the background. Light text against darker backdrops in Mail, Safari Reader, Calendar, and more makes everything easier to read in low lighting conditions. And the Accessibility preferences for increased contrast and reduced transparency work with Dark Mode enabled.
DictationYou say it. Mac types it.
Dictation lets you talk where you would type — and it works in over 40 languages. So you can reply to an email, search the web, or write a report using just your voice. Navigate to any text field, activate Dictation, then say what you want to write. macOS also comes with more than 50 editing and formatting commands. So you can turn on Dictation and tell your Mac to bold a paragraph, delete a sentence, or replace a word. You can also use Automator workflows to create your own Dictation commands.
SiriStreamline the things you do every day.
Siri helps you do more with your desktop.³ Ask Siri to send messages, track down files, create reminders, search the web, and even turn on and off VoiceOver and Invert Colors, without interrupting what you’re doing on the keyboard. And because Siri is integrated with VoiceOver, you can ask it to find a file and hear the answer read out loud. If you prefer to communicate by typing, you can easily set Siri to “Type to Siri” mode.

ZoomMake your screen up to 20 times bigger.
Zoom is a powerful built-in magnifier that lets you enlarge your screen up to 20 times, so you can better see what’s on the display. You can zoom using full screen or picture-in-picture, allowing you to see the zoomed area in a separate window while keeping the rest of the screen at its native size. A shortcut key lets you pan the screen without moving the pointer while zoomed in. macOS can also flash the screen for notifications offscreen or speak text under your pointer. The hardware acceleration engine lets you boost the size of anything on your screen — text on a web page, family photos, or a place on a map.
Zoom DisplaySee content up close and at a distance simultaneously.
Now with macOS Catalina, if you have two displays, you can keep one zoomed in close while the other stays at a standard resolution. So you can tackle everyday work or give a presentation more efficiently.
Cursor SizeMagnify your cursor so it’s easier to use.
macOS lets you magnify your cursor so it’s easier to see where you are and follow along as you move around your Mac. Set the cursor size once and it stays magnified even when its shape changes. And when you swipe back and forth on your trackpad or quickly shake your mouse, the pointer grows so it’s easier to locate.
Contrast and Color OptionsInvert colors or enable color filters.
macOS lets you invert colors, enable grayscale, or choose from a range of color filters to support different forms of color blindness or other color vision deficiencies. You can select a common preset or fine-tune the color tint and hue to customize a display setting that works for you.
Reduce MotionDecrease the movement of onscreen elements.
If you’re affected by the motion of screen elements, you can turn on Reduce Motion to decrease movement in areas like Spaces, Notification Center, and the Dock.
Music, Podcasts, Books and TVNavigate and play with VoiceOver.
The Apple Music, Apple Podcasts, Apple Books, and Apple TV apps are compatible with VoiceOver, so you can navigate and play all your content even if you can’t see the screen. Browse the apps as VoiceOver reads out headers, links, and other elements on the page.
