How can I write a really good mode?

"What are good ways to developed a software that support NFC reader/write mode in java?"

• I want to use the USB based NFC reader/write to write data on tags. But How to develop the software to detect the USB device and write data to tag and stored in DB. please answer those who developed it already. thanks

• Answer:

  Hi, I have developed with NFC and UHF readers using both pure Java and Android APIs for NFC and NDEF support. Also I have developed software for usb RFID readers undrr C# and C++. I can tell you that your best chances are using libraries and sdk provided by manufacturers, since trying to do it from ground would be time consuming and inpractical. This libraries and sdk already bring all the protocol's and standard's functionalities needed to interact with other RFID objects (i.e. cards, phones, readers, etc) although some of them, specially mane manufactured by many low level chinesse companies lack some functionalities. Nevertheless if this could be your case, that you got into one of this companies' sdk then you would have a lot of the needed job already done. I would recommen, without having anything to do with them, but because I have implemented several projects in Colombia importing their equipment, ACS (Advanced Card Systems) one of the largest manufacturers in the world of RFID readers. Their prices are a bit higher than other companies' but their libraries and sdk are great for programming in Java. They also work great with a lot of community libraries you can find on google and forums over the internet, since a lot of people works with these readers so they have done a lot of development for them. Hope it helps.
