the acquirer is configured to acquire the identification information and the management information in the corresponding one of the plurality of bases from the database.

6. The article management system of claim 1 , wherein

the electronic tag is a coating-type tag.

7. The article management system of claim 6 , wherein

the electronic tag is configured to, while transmitting data to the reading device, transmit a plurality of correction bits for correcting a capturing timing of the data, and

the plurality of correction bits are inserted at different locations in accordance with a type of the electronic tag during transmission of the data.

8. The article management system of claim 6 , wherein

the electronic tag is configured to, while transmitting data to the reading device, transmit a plurality of correction bits for correcting a capturing timing of the data,

the electronic tag is configured to transmit a preamble in transmission of the data to the reading device, and

the reading device is configured to read, based on a bit sequence between the preamble and a top correction bit of the plurality of correction bits, a timing at which the plurality of correction bits are inserted.

9. The article management system of claim 6 , wherein

the reading device is configured to perform communication based on a plurality of frame formats according to a property of the electronic tag.

10. The article management system of claim 1 , further comprising the reading device configured to read the identification information from the electronic tag.

11. A reading device to be applied to the article management system of claim 1 , the reading device comprising:

a reading unit configured to read the identification information from the electronic tag; and

a communicator configured to transmit the identification information read by the reading unit to the acquirer.

12. An article management system comprising:

an acquirer configured to acquire identification information and management information, the identification information being read from an electronic tag by a reading device in each of a plurality of bases in a distribution channel for an article, the electronic tag being attached to the article and storing the identification information, the management information being collected in association with the identification information in a corresponding one of the plurality of bases, the management information relating to management of the article, and

a management unit configured to manage the article with reference to the identification information and the management information which are acquired by the acquirer in each of the plurality of bases, wherein

the electronic tag is a coating-type tag,

the electronic tag is configured to transmit a preamble in transmitting data to the reading device, and

the reading device includes a decider configured to decide validity of the data transmitted from the electronic tag in accordance with whether or not a period of the preamble is within a predetermined range.

13. A reading device to be applied to the article management system of claim 12 , the reading device comprising:

a reading unit configured to read the identification information from the electronic tag; and

a communicator configured to transmit the identification information read by the reading unit to the acquirer.

14. An article management system comprising:

an acquirer configured to acquire identification information and management information, the identification information being read from an electronic tag by a reading device in each of a plurality of bases in a distribution channel for an article, the electronic tag being attached to the article and storing the identification information, the management information being collected in association with the identification information in a corresponding one of the plurality of bases, the management information relating to management of the article, and

a management unit configured to manage the article with reference to the identification information and the management information which are acquired by the acquirer in each of the plurality of bases, wherein

the electronic tag is a coating-type tag,

the electronic tag is configured to transmit a preamble in transmitting data to the reading device, and

the reading device includes a determiner configured to determine, based on a period of the preamble, a capturing timing of the data transmitted from the electronic tag.
