In actual applications, electronic seal is divided into passive type, semi-passive (semi-active type) and active three classes according to the first radio frequency chip in it.
Passive type electronic seal, as the electronic seal 20 in the first embodiment, does not have internal power supply, and its internal integrated circuit drives by the electromagnetic wave receiving, and electromagnetic wave is sent by reader.In the time that seal receives signal, send data to reader, these data not only comprise (global unique identification ID) No. ID, can also comprise the data in the EEPROM (Electrically Erasable Programmable Read Only Memo) being pre-existing in seal.
Generally speaking, the seal antenna of passive type electronic seal has two tasks, and first: receive the electromagnetic wave that reader sends, to drive the first radio frequency chip; Second: when electronic seal return path signal, need to lean on the impedance of seal antenna to do to switch, could produce 0 and 1 variation.Want to have the effect of best passback efficiency, the impedance of seal antenna must design in " open circuit and short circuit ", can make like this signal reflect completely, cannot be received by the first radio frequency chip.Semi-active type seal is exactly in order to address this problem.Semi-active type is similar to passive type, but its many compact battery, energy can drive the first radio frequency chip just, makes the first radio frequency chip in running order.Its advantage is, seal antenna can the electromagnetic task of not responsible reception, fully as the use of return path signal.Compared with passive type, semi-active type has reaction velocity faster, better efficiency.
Difference active and passive type and semi-passive is: active electronics seal itself has internal electric source supplying functional, in order to supply the first radio frequency chip required power supply.In general, active electronics seal has long distance and the larger memory body capacity of reading, and can be used for storing some appended messages that reader sends.
In addition, according to the frequency of operation of radio frequency chip, can be divided into low frequency, high frequency and three levels of ultrahigh frequency.

It is worth noting, in 13.56MHz frequency range, mainly containing two international standards of ISO14443 and ISO15693 supports, ISO14443 is commonly called as present Mifare 1 series of products, the near but low good confidentiality of price of decipherment distance, and Chang Zuowei mass transit card, access card use.The great advantage of ISO15693 is his recognition efficiency, decipherment distance can be extended to more than 1.5 meters by the reader of relatively high power, because the penetrability of wavelength is good, has the effect that reads that is better than ultrahigh frequency.
Characteristic:
1) frequency of operation is 13.56MHz.
2) except metal material, the wavelength of this frequency can pass most of materials, reads distance but tend to reduce.Seal need to be left the above distance of metal 4mm, and its anti-metal effect is comparatively good in several frequency ranges;
3) this frequency range all gets the nod in the whole world and does not have special restriction;
4) although the decline of the field region of this frequency is very fast, can produces and read and write relatively uniformly region;
