A bolometer is a device for measuring radiant heat by means of a material having a temperature-dependent electrical resistance. It was invented in 1878 by the American astronomer Samuel Pierpont Langley.
A Faraday cage or Faraday shield is an enclosure used to block electromagnetic fields. A Faraday shield may be formed by a continuous covering of conductive material, or in the case of a Faraday cage, by a mesh of such materials. Faraday cages are named after scientist Michael Faraday, who invented them in 1836.
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder, a radio receiver and transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods.
Shoplifting, retail theft, or retail fraud is the theft of goods from a retail establishment during business hours, typically by concealing a store item on one's person, in pockets, under clothes or in a bag, and leaving the store without paying. With clothing, shoplifters may put on items from the store and leave the store wearing the clothes. The terms shoplifting and shoplifter are not usually defined in law. The crime of shoplifting generally falls under the legal classification of larceny. Shoplifting is distinct from burglary, robbery, or armed robbery. In the retail industry, the word shrinkage can be used to refer to merchandise lost by shoplifting, but the word also includes loss by other means, such as waste, uninsured damage to products and theft by store employees.
Anti-theft systems protect valuables such as vehicles and personal property like wallets, phones, and jewelry. They are also used in retail settings to protect merchandise in the form of security tags and labels. Anti-theft systems include devices such as locks and keys, RFID tags, and GPS locators.
Retail loss prevention is a set of practices employed by retail companies to preserve profit. Profit preservation is any business activity specifically designed to reduce preventable losses. A preventable loss is any business cost caused by deliberate or inadvertent human actions, colloquially known as "shrinkage". Loss prevention is mainly found within the retail sector but also can be found within other business environments.
Electronic article surveillance (EAS) is a type of system used to prevent shoplifting from retail stores, pilferage of books from libraries, or unwanted removal of properties from office buildings. EAS systems typically consist of two components: EAS antennas and EAS tags or labels. EAS tags are attached to merchandise; these tags can only be removed or deactivated by employees when the item is properly purchased or checked out. If merchandise bearing an active tag passes by an antenna installed at an entrance/exit, an alarm sounds alerting staff that unauthorized merchandise is leaving the store. Some stores also have antennas at entrances to restrooms to deter shoppers from taking unpaid-for merchandise into the restroom where they could remove the tags.
Bagger, packer, sacker or bag boy (US) is an unofficial title given to a courtesy clerk at a grocery store.
A paper bag is a bag made of paper, usually kraft paper. Paper bags can be made either with virgin or recycled fibres to meet customers’ demands. Paper bags are commonly used as shopping carrier bags and for packaging of some consumer goods. They carry a wide range of products from groceries, glass bottles, clothing, books, toiletries, electronics and various other goods and can also function as means of transport in day-to-day activities.
A store detective is a member of loss prevention whose main role is to prevent and detect theft and reduce shrink in retail outlets. They do this by patrolling the store in plain clothes looking to identify members of the public who are stealing from the store. More common terms today with major retailers are loss prevention agent, detective or investigator and asset protection officer. Special officer, once common, is now rarely used, as few jurisdictions still allow it.
Bag tags, also known as baggage tags, baggage checks or luggage tickets, have traditionally been used by bus, train, and airline carriers to route checked luggage to its final destination. The passenger stub is typically handed to the passenger or attached to the ticket envelope:
- to aid the passenger in identifying their bag among similar bags at the destination baggage carousel;
- as proof—still requested at a few airports—that the passenger is not removing someone else's bag from the baggage reclaim hall; and
- as a means for the passenger and carrier to identify and trace a specific bag that has gone astray and was not delivered at the destination. The carriers' liability is restricted to published tariffs and international agreements.
Vacuum packing is a method of packaging that removes air from the package prior to sealing. This method involves placing items in a plastic film package, removing air from inside and sealing the package. Shrink film is sometimes used to have a tight fit to the contents. The intent of vacuum packing is usually to remove oxygen from the container to extend the shelf life of foods and, with flexible package forms, to reduce the volume of the contents and package.
An antistatic bag is a bag used for storing electronic components, which are prone to damage caused by electrostatic discharge (ESD).
Book store shoplifting is a problem for book sellers and has sometimes led stores to keep certain volumes behind store counters.
An intelligent banknote neutralisation system (IBNS) is a security system which protects valuable items by rendering them unusable or easily detectable if an unauthorised individual tries to gain access to them. Dye packs are commonly used to safeguard currency against bank robberies in this manner; when such a pack is taken out of the bank, it releases an indelible dye that stains the money with a conspicuous bright color, making it easy to recognise as stolen. Bonding agents (glues) have been used more recently as alternative degradation agents.
A bag is a common tool in the form of a non-rigid container. The use of bags predates recorded history, with the earliest bags being lengths of animal skin, cotton, or woven plant fibers, folded up at the edges and secured in that shape with strings of the same material.
Theft from libraries of books, historical documents, maps and other materials from libraries is considered a significant problem. One study commissioned in the UK estimated the average loss rate of libraries to theft at 5.3%.
A security bag is a heavy duty bag used to contain high-value products or documents or legally sensitive items. Envelopes with security features are called security envelopes as well as security bags. Cash for deposit in a bank is often placed in a special deposit bag with security features. When used to contain items related to a crime, special evidence bags are used. Authentication of signatures and chain of custody are often required.
Shirley Sally Pitts, later Shirley Sally Hawkins, was an English fraudster and thief known as the "queen of shoplifters". Born into poverty and crime, she began to steal as a child to feed her siblings. She was educated in shoplifting by the Forty Elephants, also known as the Forty Thieves, and later diversified into other non-violent crime such as fraud.
Evidence packaging involves the specialized packaging methods and materials used for physical evidence. Items need to be collected at a crime scene or a fire scene, forwarded to a laboratory for forensic analysis, put in secure storage, and used in a courtroom, all while maintaining the chain of custody. Items might include DNA, drugs, hair samples, body parts, blood samples, sperm, knives, vomit, firearms, bullets, fire accelerants, computers, checkbooks, etc.
