Double keying verification is a process used to enhance data entry accuracy by requiring two separate individuals or systems to input the same data independently. After both entries are completed, the system compares the entries to identify any discrepancies. This method is commonly used in industries where precision is critical, such as finance and healthcare, to minimize errors and ensure data integrity. By implementing double keying, organizations can significantly reduce the risk of data entry mistakes.

What are three main types of shift keying?
The three main types of shift keying are Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK). ASK encodes data by varying the amplitude of the carrier signal, FSK uses different frequencies to represent data bits, and PSK changes the phase of the carrier wave to convey information. Each type has its own advantages and applications in digital communication systems.

What does the acronym 'BPSK' mean?
The acronym "BPSK" stands for burst pulse shift keying. Burst pulse shift keying is the simplest form of phase shift keying or PSK known currently to exist.
What is the exact definition of differential phase shift keying?
differential phase-shift keying (′dif·ə′ren·chəl ′fāz ′shift ′kē·iŋ) (communications) Form of phase-shift keying in which the reference phase for a given keying interval is the phase of the signal during the preceding keying interval. Also known as differentially coherent phase-shift keying.Above retrieved from Answers.comViper1
What is meant by the phrase keying in?
The definition for "keying in" depends on the device being used. For telephones (including mobile phones), "keying in" information means using the numeric keypad to provide information (e.g., account number, spelling of last name, etc.). For calculators, "keying in" information means using the calculator keypad to enter numbers and execute operations on those values. For computers with a numeric keypad, "keying in" information means entering numbers into a particular program. For computers with a standard keyboard "keying in" information means typing in information.
