What does a Chip and PIN reader do?
A Chip and PIN reader is a device used to process card payments securely. It reads the embedded microchip on a credit or debit card and requires the user to enter a Personal Identification Number (PIN) for authentication. This dual-layer security helps reduce fraud by ensuring that only the cardholder can authorize transactions. Chip and PIN technology is widely used in many countries to enhance payment security.
Is adc present on chip in 8051 or not?
There is no formal adc input on the 8051. However, the CMOS version of the chip can use a technique involving a resistor, diode, and capacitor, along with a bidirectional pin (or one output pin and one input pin) to implement a "quick and dirty" adc function. You discharge the capacitor and then let it charge to the voltage of the input. You measure the time it takes to see the input pin change, and you calculate the input voltage.
Are chip and pin cards widely accepted in the USA?
Chip and PIN cards are becoming more widely accepted in the USA, but they are not yet as common as in some other countries. Many businesses have upgraded their payment systems to accept chip cards, but some still rely on magnetic stripe technology. It is recommended to have a chip and PIN card when traveling in the USA to ensure compatibility with most payment terminals.
Are chip and pin credit cards widely accepted in the USA?
Yes, chip and PIN credit cards are widely accepted in the USA, but they are not as common as chip and signature cards. Many merchants in the USA have upgraded their payment terminals to accept chip cards for added security.
Why first pin of ic 7806 is used as input?
Because that is the way the chip was designed. No special reason.
Explain the pin dia gram of IC 7812 belonging to category of logic gates?
The 7812 is not a logic gate. It is a three terminal voltage regulator with an output of +12V.Looking at the pins of the TO-220 device, with the flat side down, the left pin and the case is common, the center pin is input,and the right pin is output. For the smaller TO-92 78L12 device, the left pin is output, the center pin is common, and the right pin is input
What are the common payment methods used in market stall?
The most common payment method used in market stalls would be cash. Another payment method would be a chip and pin service to except debit and credit cards.
What data is output in a monitor in a supermarket?
Barcode Scanner. Touch Screen. Chip and Pin Device. Magnetic Strip Reader. Keypad. Keyboard.
3 What is meant by the term chip and pin?
By paying with the CHIP, it means that you have put an amount of money on your bankcard and you can pay small amounts without having to use a code (this system is currently in use in the Netherland). By pay with your pin code (a 4 figure code), you can have the payment deducted directly from your bank account.
