ISO and EPCglobal Protocols and Standards

The International Standards Organization (ISO) and EPCglobal are two organizations that work together to approve standards and protocols in order to provide universal specifications for RFID equipment. By creating global standards, these organizations enable the possibility of worldwide adoption of UHF RFID. Once ratified, protocols define communication methods approved with the air interface in conjunction with the operating frequency, channel bandwidth, frequency hop rate, etc.

The EPCglobal and ISO standards that are familiar today are largely due to the strides made by the Auto-ID Center from 1999 to 2003. The Auto-ID Center was, a non-profit organization made up of leaders in the RFID industry, and backed by large corporations like Walmart. In 1999 the Auto-ID Center created the first EPC standards as well as their own air interface protocol, both instrumental in attempting to commercialize UHF RFID. The other reason that the Auto-ID Center was so important is because it transitioned into two separate organizations: EPCglobal took over the commercialization of EPC technologies, while Auto-ID Labs continued the research and development role of the Auto-ID Center.

To simply explain the technology that OPP IOT offers, RFID is a chip that goes onto a wristband/cards, and upon that chip, information is placed that can only be read by certain operators. On that chip, operators can build various zones of access within their festival or event.

Organizers can use the technology to control their own event, in particular to monitor crowd movement through different areas of their venue. VIP guests, for example, can enter an event through the gates with the general audience but the data stored on the chip will allow them access into restricted VIP zones as well.

The same was done in one of our events this year, Neel City Club’s Dandiya Festival. The VIP guests had different entries than the general people wherein the VIP guests could enter from the general gates but the general ones couldn’t enter through the VIP gates. We’re now seeing the popularity of this technology spread all over the country as more and more of the world’s biggest live events begin to adopt RFID.


Cashless payment solution is quickly becoming popular in many festivals and live events.

With fast transaction times, they offer a speedy and convenient way to spend. This service cuts ticketing costs, reduces cash handling risks and offers event organizers new opportunities for revenue and sponsorship.

OPP IOT’s cashless system is fully integrated with access control technology. The event goers can use  RFID Wristbands for making purchases at the events  and also can be used  as tickets for entry.

Students Attendance Automation:
Access control is a system which enables an authority to control access to areas and resources in a given physical facility or computer-based information system. An access control system, within the field of physical security, is generally seen as the second layer in the security of a physical structure.
Access control is, in reality, an everyday phenomenon. A lock on a car door is essentially a form of access control. A PIN on an ATM system at a bank is another means of access control.
Time Attendance Recorder:

Software to manage or monitor the time worked by employees for the purpose of efficiently processing payroll.
These systems may be integrated with existing payroll processing software or Excel calculation formats.

RFID Application In the Campus

With the construction of “digital campus”, guards agai nst the product application in the campus are more widely, has become a major part of the construction of digital campus.Colleges and universities, especially in the area is large, the construction, population density is big, the vast majority of teachers and students are all forms of boarding.Dividing according to region, key prevention area of colleges and universities generally have teaching areas, living area, public area, as a dorm/apartment living area is the key of the safety management.

Student dormitory management method in the traditional manual administration through the dormitory administrator, as the room in the dormitory building, students, one to two dormitory administrator is difficult to have a whole apartment building energy management.So this method can cause certain security hidden danger, cause some dorm/apartment management problems:
1, management confusion, easy due to human negligence let some foreign sundry to interfuse, cause students’ personal and property safety hidden trouble.
2, knowing time-consuming and workload big, affect students’ schedule.
3, students to live in apartment buildings.
4, dormitory management personnel to send mails, letters, etc. Can’t timely sent to the students.

With the development of RFID technology, more and more universities begin to RFID technology is adopted to improve the students’ dormitory/apartment attendance management.Put through at the entrance of a dormitory building barrier-free access (due to the dorm/apartment fire requirement, don’t usually takes the form of brake machine.)To clock in and out of the personnel, at the same time, the joint video surveillance, access control management of a variety of ways, to student dorm/apartment security environment.In the application of RFID technology at present according to different divided into low frequency and high frequency band at close range, high frequency different technologies, such as over a long distance.And each technology category is different according to its own characteristics in the application.Differ as a result, the rapid development of RFID technology is increasingly mature.For application were also includes all aspects of life.As a college student dorm/apartment management “safe campus”, the core part of the “digital campus” construction, its development has also been the advance of RFID.It is because of the application of RFID technology, we now can only be more ascension to ensure the safety of the students in the school.The logistics management school dormitory also suddenly up easily.

Advantages of RFID in access control

Contactless identification with limited read distance. Just a simply touch will the card be indentified. Limited read range also provide user protecting their user’s data and prevent unwanted operation

Access control data management. RFID technology help users more efficiently manage visitor’s access data, such as vistor’s profile, password and access authority through relevant RFID software. Time attendance system is based on this idea.

Security . RFID provides reliable security features either by its unique ID and password or by its encryption algorisms. Especially when advanced DES and 3DES encryption algorisms introduced, user data by nowadays technology is impossible to break.
