A versatile transaction scanner for use in a food and beverage venue, comprising an optical reader and a wireless transceiver, which is adapted to read transaction information encoded within a transaction code, and transmit the transaction information to a point of sale system for processing. The transaction scanner can be used by a user who is a venue staff member to scan transaction codes representing new customer orders which are then received by the point of sale system and prepared by the venue. The transaction information may further contain payment information, allowing the transaction to be processed and completed with a single scan. The transaction scanner may further comprise a vibration mechanism which alerts the user when the customer's order is ready to be served. The transaction scanner may also have an integrated bottle opening mechanism, allowing a bartender to simultaneously take beverage orders and open bottle caps.
