PayPal is a reputable and widely used check-free online payment service, as of 2015. PayPal accounts can be connected to a bank account and credit card for safe, streamlined transactions.
PayPal can be used to buy and sell goods or services, as well as to send or receive funds. Many e-commerce sites support the popular service by providing the PayPal option at their checkout screens.
In addition to PayPal, many banks offer their customers secure electronic fund transfers, which don't require the use of checks. The availability and specifications of these online payment options are dependent on location and financial institution.
