Invoice recognition and network query integrated machine based on magnetic resonance recognition and GPRS

The utility model relates to an invoice recognition and network query integrated machine based on magnetic resonance recognition and GPRS, comprising a microprocessor unit, a frequency generation unit, a modulation unit, a power amplification unit, an antenna, a demodulation unit, a signal processing unit and an AD conversion unit, and also comprising an LED indication unit, a voice broadcasting unit, an LED display unit and a GPRS module unit respectively connected with the microprocessor unit, wherein the GPRS module unit is in wireless bidirectional digital communication with a tax department database. The integrated machine not only can determine the true and false of an invoice by using a magnetic resonance anticounterfeiting technology, but also can support information inputting such as invoice number inputting, and be networked to the tax department database for querying the true and false of an invoice, thus realizing multi-use of the machine.
