providing two or more fields for entry of data on a display screen of a client information processing system;
receiving data via a first field and displaying the received data on the display screen;
upon completion of receiving data via the first field, automatically determining whether the data entered into the first field is valid by transmitting the data in the first field to a server information processing system to validate the data, while concurrently allowing entry of data into another field of the two or more fields;
repeating the receiving step and the determining step for one or more of the remaining two or more fields;
if the data in any of the fields is invalid, transmitting from the server information processing system to the client information processing system information indicating the data is invalid; and
providing to the server information processing system, upon the determination that data entered into the two or more fields is valid, the data entered into the two or more fields.
