an e-check is usually a fee based payment option, depends on your bank, and the services, or if there are cross border fee's.. The company that offeres the e-check service may charge the purchaser of the e-check a fee.

It is not a very secure method of payment, similar to writing a bank check, only it's all done electronicaly. You need a checking account to pay via an e-check.

With an e-check, the safety/security of the transaction all depends on the integrity of the merchant and the provider of the e-check service.

Sellers must wait for funds to clear.

Extremely difficult to recover in cases of fraud.
