Administering Recurring Payments From Your PayPal Account

You can create, modify, suspend, reactivate, or cancel recurring payment profiles from your PayPal account. You can also list all recurring payment profiles. To access the PayPal Recurring Payments tools, click Recurring Payments from the Tools section of your account overview.

You can also access recurring payments reports from the PayPal Business Overview page.

Website Payments Standard enables you to accept online payments from customers with — or without — PayPal accounts.

  • Accept all major credit/debit cards (Visa, MasterCard, American Express, and Discover), eChecks, bank transfers, and PayPal accounts.
  • Easily create payment buttons (like Buy Now and Add to Cart) for your websites with PayPal tools. You design the button features, and the tools generate all the HTML code for you.
  • Does Website Payments Standard support multiple currencies?

    Yes. You can buy, sell, send, or receive payments globally in currencies supported by PayPal.

    39) What is a visible activity?

    A visible activity is one that sits behind a foreground dialog. It is actually visible to the user, but not necessarily being in the foreground itself.

    What do my buyers see when they check out?

    Your customers go through a 4-step process to pay for a purchase:

  • They click the payment buttons next to the selected items.
  • If they have a PayPal account, they log into PayPal. If they don’t have a PayPal account, they enter all their payment information on a web page protected by PayPal.
  • They review and complete the purchase on PayPal.
  • They return to your website.
  • For an illustration, refer to the section “The payment experience” on the Website Payments Standard overview page.

    Does the gateway support the countries and the currencies where you do business?

    Some gateways only support transactions in certain countries or transactions in certain currencies, limiting e-commerce opportunities. Be sure to choose a gateway that supports the countries and currencies where you expect to do business.

    Global businesses in particular may want to consider using multiple gateways which allows them to route transactions based on their geo-location. Having a second gateway also lets you conduct A/B split tests to determine which has higher acceptance rates based on key criteria relevant to your business.

    29) What role does Dalvik play in Android development?

    Dalvik serves as a virtual machine, and it is where every Android application runs. Through Dalvik, a device is able to execute multiple virtual machines efficiently through better memory management.

    This file is essential in every application. It is declared in the root directory and contains information about the application that the Android system must know before the codes can be executed.

    1 How can two Android applications share the same Linux user ID and the VM?

    The applications must sign in with the same certificate in order to share the same Linux user ID and the VM.

    28) How can the ANR be prevented?

    One technique that prevents the Android system from concluding a code that has been responsive for a long period of time is to create a child thread. Within the child thread, most of the actual workings of the codes can be placed, so that the main thread runs with minimal periods of unresponsive times.

    How long does it take for funds to show up in my PayPal account?

    Just a few minutes — when customers pay with credit or debit cards or a balance in their PayPal accounts. Payments made with eChecks take longer, because they have to clear the bank.
