摘要:
The brushhead, which has a rotating action, includes a bristle plate and three separate sets of bristle tufts. A first set of bristle tufts extends longitudinally down the approximate center of the brushhead and is arranged to extend vertically from the base plate. The second and third sets of bristle tufts are arranged on opposing sides of the first set of bristle tufts, with the second and third sets of bristle tufts being arranged at an angle outwardly, in opposing directions, from the first set of bristle tufts, the angle being in the range of 5°-45°. The length of all the bristle tufts is established so that the tips of the bristles in the first, second and third sets of bristle tufts form a shallow arc.

A user can customize use of a payment card, which can be an electronic card, by selecting a customization variable for any given transaction. The customization variable involves at least one of the following steps: (1) customizing generation of a one-time card number; (2) customizing a user identifier; or (3) inclusion of a customization variable with information transmitted to a verification agency for validation of the given use. Multiple payment card transactions can be processed differently depending upon which customization variable is chosen for a given transaction. Different customization variables can be used for different accounts, different types of transactions, or to classify the transactions. A user can receive one bill, or multiple bills. Different levels of privacy can be accorded to transactions that use different customization variables. A user may pay the issuer for increased security, or the user may be paid by the issuer to allow transaction data to be distributed to third parties.
