PayPal's eCheque feature allows you to transfer money directly from your bank account to another user's PayPal account. eCheques differ from Instant Bank Transfers, as they are not instant payments.
With eCheque payments, your bank account will be debited when the transaction is initiated. However, the recipient will typically receive the funds seven to nine working days later.
To make an Instant Bank Transfer you must have an up-to-date credit or debit card registered to your PayPal account, as well as your bank account. This will be used as a back-up funding source in case the bank transfer fails.
