Camaweigh NFC Cards
What are NFC cards and how do they benefit the weighing industry? NFC or Near Field Communication is a communication technology which enables communication via short range distances between capable devices. The NFC process requires a minimum of one source device transmitting a signal and another device or devices receiving the signal. Various devices can make use of the NFC technology and can be considered either active or passive. Passively enable NFC devices are ones which can send signals to other NFC devices on their own and don’t need any power source. NFC cards, tags, and bar codes are some examples of these passive devices. Passive NFC devices can’t be used to send data to other passive NFC components. If you will notice these types of devices like NFC cards only interact with receiving devices. NFC cards can be used with other NFC cards since no processing of signals and data would be taking place. Active devices, on the other hand, have the ability to do both. They can actively send and receive data. Active NFC devices can interact with passive NFC devices and with their own kind.
Benefits of NFC Cards in the Weighing Industry
In the weighing industry, NFC cards are being used as accessories which can help in being smart weighing systems. Camaweigh’s offers NFC cards which can be programmed and used with their line of boom barriers. Camaweigh’s NFC cards deal a very great deal of importance when it comes to overall efficiency in the weighing process. They eliminate the requirement of human presence because of its wireless communication capability. Similar to other wireless communication technology like WIFI, Bluetooth and infrared, the working principle of NFC is pretty similar. They all send data and information through radio waves. Near field communication devices need to follow certain parameters and specifications for proper transmittal of signals to work. NFC cards and other NFC devices make use of an older RFID system which makes use of electromagnetic induction to send data. This is one of major difference with WIFI/Bluetooth and NFC technology. NFC cards and other devices have the ability to induce electrical signals within passive NFC devices. As mentioned before, passive devices don’t have their own power supply to be operated.
NFC cards are used in almost all kinds of industries. Not only are they used in the weighing industry but they can commonly be found in residential and office properties. NFC technology is now used as an additional security detail. Many condominiums have adapted it to their security system in order to manipulate or to check the people going about their property. The active NFC device, which is the reading device, reads the NFC cards given to each individual user. The NFC need to be tapped or just close enough to be read. The sending of data happens pretty fast depending on the programming of the receiving device.
Camaweigh’s NFC Cards
Camaweigh’s NFC card, the MIFARE Classic EV1, is one of the widely used all over the world. Their NFC technology started a contactless revolution which made rise to its numerous applications. The NFC cards offered by Camaweigh is the most developed of all the products in the MIFARE Classic product line.
Camaweigh started offering these NFC cards as an accessory because of their NFC enabled automatic boom barriers. As mentioned before, Camaweigh can assemble a smart weighing system for their customers depending of their requirements. An example of a complete weighing system consists of weighbridge, boom barriers, traffic lights, and NFC cards. NFC cards assigned to each vehicle or truck is tapped by the user on the reader in order to open the boom barrier. This is very efficient for the weighing process, because without the use of NFC cards, the boom barrier would need to be manually operated.
