A client to whom a mailer is provided directly upon setting up electronic banking doesn't have to wait for delivery of the mail. Thanks to this, he or she can much more quickly begin using electronic banking services whose use requires identification data delivered via the mailer.
The distribution of mailers via one's own means represents a positive factor in the security of key data: these data are not entrusted to a third party.
The production of mailers by an external provider can, with a view to the technological background of a specialized firm, bring a higher level of technical design of the mailers than would be possible to achieve in the case of printing mailers under the bank's conditions.
