Because it's much, much easier to design electronic two-way switches that electronic ten-way switches. A two-way switch leads to binary.
Electronic fund transfers are very important in the banking sector. They are convenient, faster, and easier. They also eliminate the need for paper checks.
Electric is easier and faster then mechanical processing, Your question does not give much information but look into Binary, Dont look into computers, Binary is a counting system like our counting system decimal (0,1,2..,9,10,11,12...,19,20,21 ect). We use binary as it is base 2, And electric can have two states, on or off (1 or 0). To use decimal we would need to be able have 10 different values.
Binary coded decimal (BCD) is easier to convert between displayed or printed form than is pure binary.
binary
Little bit easier.
It is the easiest way to do it reliably: on/off signals are easier to distinguish than more levels. Note: there were a few computers built in the USSR that used ternary numbers instead of binary (e.g. + voltage, 0 voltage, - voltage). They worked but the circuits to identify the 3 levels were much more complex than for 2 levels.
It is used because it is easier to convert to and from binary to hexadecimal than decimal, and it uses less characters than binary. For instance: decimal: 65535 hex: FFFF binary: 1111111111111111
If you are referring to EBT, it means electronic benefit transfer. It is the new name for food stamps, in the electronics form of benefit. It comes in a credit card format and is easier and faster to use and receive benefits.

We need to use electric circuits so as to make the transfer of electricity easier. you must have seen various paths made in the circuits, these path controls and regulates the flow of current . But if we don't use electronic circuits then we will have to use wires which is very difficult to handle when we have to do large no. of operations li in computer.
Binary is easier for the computer to understand. It is also easier to handle and is not costly.
