EDM, Inc. has provided RFID card and ticket products to the transportation industry for nearly 20 years. Specializing in the transit industry means we provide Smart products using the MiFare® IC Family. You may have heard of Ultralight®, Ultralight Nano®, Ultralight C®, MiFare Classic 1K® and DesFire®…. These are a few of the more popular MiFare® products offered by EDM today.

EDM works with major equipment OEM’s such as Cubic Transportation Systems, SPX Genfare, Conduent-Xerox, iNiT, VIX, Scheidt & Bachmann and others… Our relationships go back decades as does our expertise and experience in producing Smart products for transportation.

EDM offers both “Extended Use” and “Limited Use” Smart products. Our “Smart Card Plus” products made from 100% polyester for increased durability. These products have been developed specifically for our transit customers. One can utilize any of the MiFare® family of chips in either construction. Of course, we also provide the standard PVC and paper-based RFID products as well.

Most all RFID products come in the shape of a credit card. We can provide our Smart products in a variety of formats. Single-cut is the dominant format when providing “Extended Use” cards such as our 30-Mil Smart Card Plus. EDM also provides smart products in roll or folded formats. These formats are commonly used to dispense our “Limited Use Smart Card Plus” products.

EDM has helped create specifications with our OEM partners and give insight into problem areas that may occur in the real world. We helped one OEM partner design an RFID direct thermal plastic card that works in their legacy transport mechanism using thin gauge paper tickets. EDM completed this project in roughly six months!

Our customers ask many questions about RFID.

"What is RFID?"

Put plainly it is radio wave communication between a read/write module and the IC (integrated circuit or chip) in a Smart card or ticket. The read/write module sends out electromagnetic waves having both power and data. This wave of energy will power the chip and, in milliseconds, the IC sends a message back to the module. This interaction can be read-only or read-write. This communication can take place literally hundreds of times a second.

"Is RFID secure?"

Many of the MiFare® IC’s come with encryption. Generally, the OEM will create an algorithm for a specific customer to encrypt data and control communication between read/write modules and fare media. This is known as the “Key”. One must have the “Key” for communication with Smart card and ticket products in a given system. The “Keys” are made specific to individual agencies to prevent counterfeiting. Should the IC not have encryption capabilities, the data itself is encrypted to prevent duplication.

"How much data can a Smart card hold? How much memory do I need?"

These questions go hand in hand. To answer the “how much Data” question, I use a spreadsheet analogy… the smaller IC’s have one or two rows with a few columns to store data. The larger IC’s have hundreds of rows, hundreds of columns and multiple tabs to represent different applications on a single card. The answer to “how much memory” largely depends on the system architecture. Some agencies store all the data on the card and others use an “account-based” architecture, using the card as merely a license plate or a number. In the first scenario, all the transactions take place on the card. Card-based systems may demand more memory requiring greater IC size and capability. The account-based model relies on all transactions taking place, in real time, on the central server. Here, we may only need a single unique number on the card itself requiring very little memory at all.
