When RFID was applied in the initial stage of the industrial laundry industry, high frequency (13.56MHz) was the only available RFID technology. RFID laundry tags are usually sewn on clothing. The labeled clothing will be read every time it passes through a processing stage so that the whole process can be managed and monitored. Normally, RFID reading points are set up at receiving, sorting, washing, drying, ironing, folding, sorting, shipping, and distribution locations. These labels must be able to withstand the chemicals used in the cleaning process, as well as the high temperatures in the washing, drying, and ironing processes and the life of these labels must be longer than the life of the clothes.
In December 2004, a new RFID standard passed the certification: EPC Gen 2, the new UHF standard, brought changes in RFID in the laundry industry. Compared with high-frequency tags, Gen 2 RFID has a longer reading distance, increasing from a few centimeters to a few meters. Most of the new laundry industry utilizes this latest development of RFID technology.
UHF RFID laundry tags can be sewn directly on towels, bathrobes, or sheets, and report information will be sent once a tagged item is taken out of the hotel area. When the RFID reader reads the tag on the item to be taken, an alarm will be issued to effectively prevent the theft from happening.
Low Frequency RFID Chip
The common main frequency is 125KHz. Generally, RFID tags in this frequency band are passive, and provide energy supply and data transmission through inductive coupling. The biggest advantage of the low-frequency RFID chip is that the tag is less affected when the tag is close to metal or liquid items. At the same time, the low-frequency system is very mature and the price of the reading and writing device is low.
But the disadvantages are the short reading distance, the inability to read multiple tags at the same time (anti-collision), and the low amount of information. The storage capacity of general chips is from 128 bits to 512 bits. Mainly used in access control systems, animal chips, car alarms, and toys.
Although the low-frequency system is mature and the price of reading and writing equipment is low, due to its low resonance frequency, the tag needs to make a winding inductor with a large inductance value, and often requires an off-chip resonance capacitor. In fact, the cost of the tag is higher than the other frequency.
High Frequency RFID Chip
The common frequency is the 13.56MHz ISM band. The RFID label in this band is still passive, and it also uses inductive coupling for energy supply and data transmission.
The biggest application of RFID chips in this frequency band is the contactless smart cards we are familiar with.
Compared with low frequency, its transmission speed is faster, usually above 100kbps, and it can be identified by multiple tags (each international standard has a mature anti-collision mechanism). The system in this frequency band benefits from the application and popularity of contactless smart cards. The system is also relatively mature, and the price of reading and writing equipment is relatively low.
High-frequency RFID chip products are the most abundant, with storage capacity from 128 bits to more than 8K bytes, and can support high security features, from the simplest write lock, to stream encryption, and even encryption coprocessors are integrated . Generally used in identity recognition, library management, product management, etc. RFID applications that require high security, this band is currently the only option.
Ultra High Frequency
The common main frequency is 860~960MHz. The RFID chip in this frequency band transmits energy and information through electromagnetic waves.
Both active and passive applications are common in this frequency band. Passive tags have a reading distance of about 3 ~ 10 m. The transmission rate is relatively fast, and can generally reach about 100kbps. And because the antenna can be manufactured by etching or printing, the cost relatively low.
Because the reading distance is far away, the information transmission rate is fast, and a large number of tags can be read and identified at the same time, it is especially suitable for logistics and supply chain management. However, the disadvantage of this frequency band is that it is less ideal for metal and liquid objects, and the system is not yet mature, the price of reading and writing equipment is very expensive, and the cost of application and maintenance is also very high.
In addition, the safety characteristics of this frequency band are general, and it is not suitable for application fields with high safety requirements.
