To speed up the 1890 census. The 1880 census using traditional hand counting methods had taken 8 years just to get the basic figures required by the constitution related to voting. It was estimated that without assistance of some kind the 1890 census would take much longer than 10 years, making its data useless.
Using Hollerith's machines the entire 1890 census was complete in a single year!

What are the features of Hollerith machine?
The Hollerith machine, developed by Herman Hollerith in the late 19th century, was an early data processing device that used punched cards to store and process information. Key features included the ability to read, sort, and tabulate data automatically, significantly speeding up census data processing. It utilized electrical connections to detect holes in the cards, translating them into numerical data for analysis. This innovation laid the groundwork for modern computing and data processing techniques.
What concept of computing did Herman Hollerith use to find a faster way to compute the US Census?
Herman Hollerith used the concept of punch cards to develop an electromechanical tabulating machine for the 1890 US Census. His system involved encoding data on punch cards that could be read by machines, allowing for faster data processing and analysis compared to manual methods. This innovation significantly reduced the time required to compile census results and laid the groundwork for modern data processing and computing techniques.
What happens when you use your debit card at a machine designed to read it?
Money is taken out of the account that the debit card is linked to.
What is the purpose of the keypunch machine?
A keypunch machine is used to encode data or instructions by punching holes in cards that will be read later by a computer using a punch card reader.
Can ATMs that grab your card without pulling it inside actually pull it inside?
All ATMs are designed to 'capture' any card inserted into it - provided that the card is 'read'. The magnetic strip on the back of the card triggers the mechanism to pull the card into the machine. Once the transaction is complete,the card is ejected. The only exception, is if the bank has for the the card to be retained - in which case, the machine keeps the card, and informs the user on the screen to contact their bank.
What is a chip reader?
it is a machine in which the pin or chip is read. hope it was helpful.
What is the purpose of the national ID card?
it is for identification and for security purposes.
What is a ledger posting machine?
a machine that records detailed transactions on a unit record ledger card. The balance associated with each transaction is summed and stored on a magnetic strip on the card. The machine can read all of the updated ledger cards very quickly to pick up the ledger balances and sum them into a totaling device.
How a punch card machine works?
A punch card machine operates by creating holes in a card to represent data or commands, which can then be read by a corresponding machine. The user inserts a blank card into the machine, and a series of mechanical or electronic components punch holes based on input instructions. Once punched, these cards can be processed by a reader that detects the presence or absence of holes to interpret the encoded information. This system was widely used in early computing and data processing before the advent of more advanced technologies.
How is magnet used in ATM cards?
ATM cards have a magnetic stripe on the back that contains information such as the card number and expiration date. When the card is swiped at an ATM machine, the magnetic stripe is read by a magnetic card reader, allowing the machine to access the necessary account information to complete the transaction.

How an ATM machine works?
ATM Machines read the card details when an ATM card is inserted and prompts the user to insert the amount of cash required, it then counts the cash and dispenses it which gets deducted from the user's bank account.
