Coding in RFID refers to a modulation pattern that is understood and shared by both a transponder and a receiver. Like Morse code–the series of dots and dashes used to transmit data in the past– radio frequency coding relies on...
In essence, data is ‘carried' on radio waves. Imagine that the radio waves are a conveyor belt. The belt moves on a steady pace never stopping, never varying. At each end of the belt sits a person, one called a...
With identity theft becoming an increasingly common and well-publicized crime, more and more campuses are opting to remove the Social Security Number (SSN) from the student ID card. A great deal of controversy has long surrounded the use of the...
One of the basic technical concepts of RFID involves anticollision. To understand anticollision we first must define a collision. An RFID collision involves multiple cards crashing into each other within a reader's field. This crash need not be a physical...
Somewhere on your campus there is, very likely, a magnetic stripe stored value system in operation. Maybe it is a full-blown part of your campus ID card enabling cashless purchases in vending machines, photocopiers, and laundry facilities. Or maybe it...
The process used by most card printers today is called ‘dye diffusion thermal transfer' or ‘dye sublimation' (dye sub). It involves the transfer of dyes from a ribbon to a plastic card via heat. The key pieces of this process...
Traditionally institutions have used barcodes to identify the student for library functions. Some campuses used the barcode for identification purposes in other administrative areas as well. In older card systems a printed barcode was often pasted to a laminated card....
The following process shows one method for generating library numbers from the student ID encoded on the mag stripe. In this case the institutions existing system utilizes a 14-digit barcode and the unique ID number encoded on the magnetic stripe...
The International Organization of Standards (ISO) laid the groundwork for the physical dimensions of magnetic stripe cards as we now know them in IS 7810, then began mapping the standardized layout for the data tracks in IS 7811.
The ANSI/ISO BCD Data format is format defines the data in encoding for Track 2. It uses 5-bits of data (zeros and ones) to create the character set. In reality, only 4 bits are used for character creation while the...
