The Tagcash NFC app is free to download and play, with the PLAY points that are embedded in the app - Usually, you will want to credit and debit from an online wallet, for central administration and tracking and you will want to know which device uploaded or downloaded your Tokens. If you have multiple sites, then again usually you will want to reocrd which location uploaded and downloaded credits. Each location in this case would be charged monthly. Any other devices using the app, if they are only being used for crediting and charging NFC cards, would not need to connect to the online wallet, and therefore not charge is made.
Pricing is $25 USD (or 70 TAG) per month for the first user license, and $10 USD (or 30 TAG) per month per user that connects to the online wallet
There are no fees charged per transaction, either offline or online. Your tokens can be sent to any other user, or even to a separate node of Tagcash Blockchain.
You have 2 options. The first is to use the Tagcash API (mainly the wallet/transfer command) - however, all your customers would need to have a Tagcash account. The registration can be done via your app as well. There are caps for API usage eg: free usage for up to 25,000 transactions per month
The second option is create a wallet node by connecting to the Tagcash Blockhain, and sending RPC-JSON commands, with commands to send Tokens to others, creating new addresses and so on. Those addresses can be tied to your users in your application. Other than the initial connection to the Tagcash Blockchain, there is no further connection to Tagcash, although all online transactions are recorded on the Tagcash Blockchain. However, the NFC transactions between device and cards is NOT stored on the Blockchain
