Abstract

Devices and systems for detecting tape or a piece of glue on a document, and methods for detecting tape or a piece of glue on a document are described. The device comprises at least one light source, at least one light receiver and at least one light barrier. The at least one light source is arranged on a first side of the at least one light barrier, and the at least one light receiver is arranged on a second side of the at least one light barrier opposite the first side. The light barrier is configured to contact the document to prevent or reduce light emitted from the light source on the first side of the light barrier from being transmitted to the light barrier. the light receiver on the second side.

Description

technical field [0001] The present disclosure relates to devices and systems for detecting adhesive tape on documents and methods for detecting adhesive tape on documents. For the purposes of this disclosure, the term "ticket" includes, but is not limited to: banknote, sheet, bill, coupon, security paper, currency, ticket , or any other flexible planar object of the same nature. Background technique [0002] Coupons of any kind are used to pay for goods. There are more and more goods sold in vending machines, such as food, toys, medicine, tickets and so on. Customers can pay at these vending machines or at automated teller machines with coupons such as checks, banknotes or gift certificates. Machines that accept tickets for transactions must provide high reliability in validating the tickets. Inserted tickets are unacceptable for several reasons. If the tickets are unacceptable, the machines will return the tickets to the user, saving the companies that operate the mach...
