Source-derived summary

MEI Conlux (formerly known as Mars Electronics International) is a manufacturer of electronic banknote validators, coin acceptors and changers. MEI was spun off to private investment interests in July 2006. In December 2012, it was sold to Crane Co., which also manufactures vending machines. A new division was created inside the company by merging former CPS (Crane Payment Solutions) and MEI into CPI (Crane Payment Innovations).

The firm began operations in Great Britain in 1965 and expanded to the United States in 1967. The firm invented the electronic vending machine and is one of the largest manufacturers of vending machines in the world. As of 2011, the company operated in over one hundred countries and processed over two billion transactions per week.

It has had a co-educational relationship with the Mechanical Engineering department of the Imperial College, London.

In 1996, the firm signed a deal with DigiCash, one of the first digital currencies. This led to the widespread integration of smart card technology in vending machines.

Editorial analysis

Why this record matters

“MEI Conlux” is worth following because a concise public description often conceals a longer documentary argument. Here, Conlux, Open-knowledge and entry provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 15, 2025. The linked authority identifier is Q6715346. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2006, 2012, 1965 and 1967.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
