qID'EM Reader

qID'EM Reader for EPC class-1 gen-2 tag ICs. Using CAEN qID'mini UHF reader.

The qID’EM Reader Android App is designed to easily demonstrate the different features of the EPC class-1 gen-2 tag ICs being developed by EM Microelectronic. The Android App works with the CAEN qID'mini UHF reader. Please check CAEN website for more details: http://www.caenrfid.it/en/CaenProd.jsp?idmod=824&parent=61

The qID'EM RFID reader supports all EPC class 1

gen2 tags, but offers enhanced user experience for

the following tags:

[EM4124] 96b EPC/UII memory, 64b TID memory, low cost passive IC for SGTIN-96 applications

[EM4126] 208b EPC/UII memory, 32b TID memory, low cost passive IC for SGTIN-96 or SGTIN-198 applications

[EM4324] 96b EPC/UII memory, 64b TID memory, 720b User memory, passive or BAP IC with tamper detection for enhanced read range or e-seal applications

[EM4325] 352b EPC/UII memory, 256b TID memory, 3072b User memory, passive or BAP IC with embedded temperature sensor, tamper detection, SPI serial interface or 4 GPIO pins for enhanced read range, temperature measurements, e-seal, sensor RF interface or microcontroller RF interface applications

[EM4423] 128/224b EPC/UII memory, 96b TID memory, 1984b User memory. This chip combines two functionalities in one single die, the EPC/Rain technology used for long range application purposes and the NFC used to exchange data in a proximity range. Both protocols may share a common unique ID.

The application presents two modes of operation:

1) A scanning window with an automatic tag soroting which natively supports the main UHF chips of the market (EM, Nxp, Impinj and other UHF/Rain ICs)

2) An Advanced tag information are available by touching any inventoried EPC code. The new windows which will pop up are depending on the selected IC. If the EM4325 is in the field and selected for advanced information, the tabs are:

a. "Tag Details" to get general information about the read tag

b. "Memory Map" for a quick preview of each memory bank content. Read and Write of each unlock memory word are available.

c. "Temp Sensor" to set new settings for the BAP temperature monitoring

d. "Live Chart" to stream with the UHF dongle the BAP temperature monitoring in a chart view

e. "SPI Master" to send SPI data to an SPI slave device. This tab appears only when the EM4325 is configured as a full-duplex SPI master device.

If the EM4423 is in the field and selected for advanced information, the tabs are:

a. "Tag Details" to get general information about the read tag

b. "Memory Map" for a quick preview of each memory bank content. Read and Write of each unlock memory word are available.

c. "NDEF Message" to interpret the NDEF contained in the tag memory.

d. "ECC Verification" to check the digital signature contained in the tag memory.

e. "Untraceable Command" to send untraceable command according to Gen2V2 spec.
