Xoom offers money transfer services, primarily from one person to another, in many countries worldwide. Money is sent securely through a desktop and mobile site as well as a mobile app. Money sent by Xoom may be received in cash at banks and various other businesses depending on the recipient's location, as well as by deposit to bank accounts. Users pay for the service using funds paid by direct debit to their U.S. bank account, a credit card, or a debit card. The Xoom fee varies based on the method of payment. Payment by direct debit to a bank account is the least expensive, while the fee payment by a debit card or credit card are much higher and are based in part on the amount being sent. Xoom acknowledges that it also makes money on the currency exchange, but the exchange rates are favorable to many other alternatives. The service employs a variety of methods to assure the integrity of users' accounts as well as to prevent fraud and money laundering. These methods include identity verification and limits on the amounts that can be transferred on per day, per month, and per 180-day period. Generally speaking these limits make it difficult or impossible to use Xoom for substantial payments. In addition banks or businesses may impose their own limits on the amounts someone may receive in a given period of time.
