A Rolodex is a rotating card file device used to store a contact list. Its name, a portmanteau of the words "rolling" and "index", has become somewhat genericized for any personal organizer performing this function, or as a metonym for a total accumulation of business contacts. In this usage, it has generally come to describe an effect or characteristic of the small-world network [1] of a business's investors, [2] board of directors, [3] or the value of a CEO's contacts, [4] or in organizational structure. [5] Models have been exhibited in the Smithsonian Institution. [6]
The Rolodex was invented in 1956 by Danish engineer Hildaur Neilsen, the chief engineer of Arnold Neustadter's company Zephyr American, a stationery manufacturer in New York. [7] Neustadter was often credited with having invented it. [8] [9] First marketed in 1958, [10] it was an improvement to an earlier design called the Wheeldex. Zephyr American also invented, manufactured and sold the Autodex, a spring-operated phone directory that automatically opened to the selected letter; Swivodex, an inkwell that did not spill; Punchodex, a paper hole puncher; and Clipodex, an office aid that attached to a stenographer's knee. [11] [12] Rolodex also marketed non-rotary (linear) tub-like card-file systems using the same cards (size and notches) as the rotary files.
Neustadter retired and sold out to a larger firm in 1970. [13] The Rolodex remained popular throughout the 1980s, and individual Rolodexes containing a large amount of information were considered valuable, and lawsuits were filed by companies against employees who attempted to take their Rolodex with them when leaving the company. A 1985 episode of the detective TV series Moonlighting involved a stolen Rolodex being ransomed for $50,000- a figure reflecting the value of the data it contained. The system fell out of widespread use in the 2000s, as digital storage became the norm. However, Rolodex cards are still produced, and have a niche usership. [14]

Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 centimetres (1.6 in) or less. NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. Like other proximity card technologies, NFC is based on inductive coupling between two electromagnetic coils present on a NFC-enabled device such as a smartphone. NFC communicating in one or both directions uses a frequency of 13.56 MHz in the globally available unlicensed radio frequency ISM band, compliant with the ISO/IEC 18000-3 air interface standard at data rates ranging from 106 to 848 kbit/s.
An address book or a name and address book is a book, or a database used for storing entries, called contacts. Each contact entry usually consists of a few standard fields. Most such systems store the details in alphabetical order of people's names, although in paper-based address books entries can easily end up out of order as the owner inserts details of more individuals or as people move. Many address books use small ring binders that allow adding, removing, and shuffling of pages to make room.

An index card consists of card stock cut to a standard size, used for recording and storing small amounts of discrete data.

Contactless payment systems are credit cards and debit cards, key fobs, smart cards, or other devices, including smartphones and other mobile devices, that use radio-frequency identification (RFID) or near-field communication (NFC) for making secure payments. The embedded integrated circuit chip and antenna enable consumers to wave their card, fob, or handheld device over a reader at the Point-of-sale terminal. Contactless payments are made in close physical proximity, unlike other types of mobile payments which use broad-area cellular or Wi-Fi networks and do not involve close physical proximity.
