Abstract: A water dispensing unit adapted for communication with a water supply includes a main body including a first end, a second end opposite the first end, a first axis extending through the first and second ends, and a second axis extending perpendicular to the first axis. The water dispensing unit additionally includes an inlet configured to receive water from the water supply, an outlet configured to dispense water, wherein the outlet extends along an outlet axis, an inner wall including a reflective liner, and a light emitting diode positioned within the main body. The outlet axis is oriented at an angle relative to the second axis to direct water from the water supply toward the light emitting diode before exiting through the outlet.

Abstract: A bankcard password protection method includes the steps: a security processor randomly generates a public and private key pair; the security processor sends a public key to an application processor; the application processor acquires a bankcard password, encrypts the bankcard password by means of the public key and sends the encrypted bankcard password to the security processor; and the security processor decrypts the bankcard password by means of a private key. In this way, the bankcard password protection method of the invention improves the security of the bankcard password input process and brings a better experience feeling to customers.
