The BannerCoin project (ICO information here -
BannerCoin.com ) was designed to allow website merchants to accept both traditional and cryptocurrency payments via their website. The system tracks the price of the coin at the time of purchase so you have a cost basis recorded at the time of received payment. This will make it much easier to know the value of each coin you received when you go to sell it and can account for the increase or decrease in value for capital gains purposes.
In addition, unlike most so-called cryptocurrency payment acceptance platforms, the BannerCoin project is geared at assisting with post payment processing. For example, if you are running an online store selling physical goods, then you'd use the ecommerce system called BannerMerchant (
BannerMerchant.com) to handle order tracking, inventory management, etc.
Most payment apps are standalone meaning they don't directly integrate with backend post transaction processing systems, don't provide good historical transactional data and don't make it so you own the customer. When you use third party payment processing systems, the third party gets to maintain a relationship with the customer. Under this model, the customer never shares information with a third party and you own the full customer engagement cycle.
