100pcs 125Khz RFID ID Card for Access Control System Or Time Clock

Product Information

As the owner of an item may not necessarily be aware of the presence of an RFID tag and the tag can be read at a distance without the knowledge of the individual, sensitive data may be acquired without consent. The main part of the RFID transponder is the RFID chip. Some chips are read-only and they contain only a preprogramed chip ID code, while others contain memory that can be written and protected in addition to an ID code. There are also chips that are completely blank, and even the ID code can be programmed later on by the application. Passive tags are powered by energy from the RFID reader's interrogating radio waves. Active tags are powered by a battery and thus can be read at a greater range from the RFID reader, up to hundreds of meters.

There are a number of different frequencies used in Access Control methods, and you can get readers which combine these together or readers which use these separately. A very common frequency, 125 KHz, is classed as a low frequency and enables a great read range of up to 1 meter in the ideal conditions, however this low frequency technology can only transmit small amounts of data. A perfect choice for these kind of low frequency RFID Cards can be found within the HID Proximity Card and SwiftProx Card range. Where gas and water mains bonding (earthing) is not in place at your property. If this is not in place, additional work would be required before installation of the charge point.RFID for timing races began in the early 1990s with pigeon racing, introduced by the company Deister Electronics in Germany. RFID can provide race start and end timings for individuals in large races where it is impossible to get accurate stopwatch readings for every entrant.

According to an RSA laboratories FAQ, RFID tags can be destroyed by a standard microwave oven; [154] however, some types of RFID tags, particularly those constructed to radiate using large metallic antennas (in particular RF tags and EPC tags), may catch fire if subjected to this process for too long (as would any metallic item inside a microwave oven). This simple method cannot safely be used to deactivate RFID features in electronic devices, or those implanted in living tissue, because of the risk of damage to the "host". However the time required is extremely short (a second or two of radiation) and the method works in many other non-electronic and inanimate items, long before heat or fire become of concern. [155]

But while these cards come in handy due to the added convenience, with the introduction of the Smart Home Charger Regulations , you will have more opportunities to customise and manage your EV charging via a manufacturer app than via an RFID card, typically resulting in cheaper and sometimes greener charging. For example, the Ohme ePod , you can find out when the electricity in the grid is at its greenest and therefore charge your EV with more renewable energy. preprogramed serial number. Some chip ID codes are programmed electronically, while others are even laser engraved during the chip manufacturing and cannot be altered or changed. The UID means chip’s Unique ID. Chips with 7-byte ID usually have a UID number which means that the manufacturers have declared them Unique IDs. Chips with 4-byte ID numbers have been so widely produced and the number range doesn’t allow manufacturers to guarantee that the chips are unique, so they have a Non-Unique ID or NUID code.Schoolchildren to be RFID-chipped".
