  • Publication number: 20220108288
    Abstract: A system and method of enhancing ‘tip’ or ‘gratuity’ management, herein referred to as a ‘Daily Tip Payment System’ (DTPS) is disclosed. One example embodiment is comprised of a software application (app), a data processor executing the app, and a cloud network. The software connects with an employer's existing point of sale (POS) platform used in retail settings (such as restaurants, etc.) and allows tips from cashless transactions to be seamlessly deposited directly into an service provider's bank account, prepaid debit card, or mobile payment app after each shift for a small fee. An object of the example embodiments of the invention is to streamline tip coordination and allocation for the employer and allow the service provider to receive tips more frequently and more conveniently.

  • Patent number: 8986399
    Abstract: A process of covalently modifying a lignocellulosic material is provided. The process includes oxidizing a lignocellulosic material having hydroxyl groups with an oxidant to oxidize at least a portion of the hydroxyl groups to carboxylic acid groups, optionally activating the carboxylic acid groups with an activating agent to form activated carboxylic acid groups, and reacting the carboxylic acid groups or the activated carboxylic acid groups with a first nitrogen-containing reagent selected from amino acids, peptides, or protected derivatives thereof to provide a treated lignocellulosic material. The treated lignocellulosic materials thus prepared displays resistance to degradation.
