NFC – Near field communication
Emulator of barcode scanner
NFC-unit extends the capabilities of the existing infrastructure of the store by introducing NFC-cards for buyers in addition to standart barcode cards. The device is placed in the gap of the line going to the barcode scanner and allows you to read NFC-tag as if it was the reading of the bar code.
Verification tests are automated and cover two areas: radio-part and communication. During the installation check of the radio part starts with output of all metrics, the results of the tests that allows the user to monitor the process and evaluate the quality of reading.
Along with ease of use and the solution of the current task NFC-block has projected in the production timeline and cost with consistently good quality.
NFC-unit extends the capabilities of the existing infrastructure of the store by introducing NFC-cards for buyers in addition to cards with standart bardcodes. The device is placed in the gap of the line going to the barcode scanner and allows you to read NFC-tag in NDEF format as if it was the reading of the barcode.
The technical side of the project consists of the following stages: creation of concepts, cultivation of the PCB in the shortest time with regard to technology standards for serial production.
From the point of view of the software carried out the implementation of the standard ISO 14444 NFC type A, and the application architecture is built using only hardware, without operating system (Bare Metal), and given the limited memory resource.
– free use of a standart barcode scanner as before,
– the library works with NFC-cards and chip reader,
– development of bootloader and software updates algorithm during workflow,
– development of library working with UART channels,
- easy to use,
projected in the production time and cost with consistently good quality.
