Overview

Digital Angel Corporation was a technology business whose activities encompassed identification, tracking, communications, and consumer software. Its earlier and better-known technology portfolio centered on Global Positioning System and radio-frequency identification systems for people, animals, food-supply chains, government and military applications, and commercial assets. The company’s products included implantable RFID identification devices, scanners, antennas, GPS and satellite communications equipment, end-to-end food-safety systems, telecommunications and security infrastructure, and search-and-rescue transponders. A particularly notable and controversial part of the company’s history was its minority ownership of VeriChip. Digital Angel formerly held a 49 percent interest in VeriChip, which was associated with implantable human RFID technology. The human-implant application generated civil-liberties and privacy concerns, making it a prominent but contentious aspect of the Digital Angel story. Digital Angel divested its VeriChip stake in 2008. VeriChip Corporation and Steel Vault Corporation subsequently combined to form PositiveID, which later attempted a friendly acquisition of Digital Angel in 2010; Digital Angel’s board unanimously rejected the proposal. Digital Angel also operated in animal identification and tracking through its Destron Fearing subsidiary. Destron Fearing supplied implantable identification products, scanners, and related equipment for pets, wildlife, and livestock. Digital Angel sold that subsidiary to Allflex USA in July 2011 for $25 million, marking a significant reduction in the company’s animal-identification activities. The company’s technology work extended beyond identification chips. It researched GPS search-and-rescue transponders that combined satellite communications with location tracking for aircraft, ships, and other high-value assets. These systems were positioned for both military and private-sector use. Digital Angel also owned Signature Communications, a United Kingdom distributor of two-way communications equipment. Signature Communications served customers requiring conventional radio systems for safety, security, construction, and manufacturing monitoring, as well as trunked radio systems for larger users such as local authorities and public utilities. The reference material also describes Digital Angel as a developer and publisher of consumer applications and mobile games for tablets, smartphones, and other mobile devices. This indicates a later or parallel effort to broaden the company beyond specialized tracking and identification hardware. The available material does not establish the duration, scale, product names, or present status of that mobile-software business. Digital Angel’s leadership changed several times during the period documented in the reference material. Randy Geissler served as chief executive from 2000 to 2003. Joseph J. Grillo became chief executive on January 2, 2008, succeeding Kevin McGrath. Daniel E. Penni became interim chief executive on February 1, 2012, and L. Michael Haller was appointed chief executive on August 23, 2012. The supplied sources do not provide enough information to determine the company’s current operating status, present ownership, headquarters, or whether the Digital Angel name remains active as a commercial brand.

History

Digital Angel Corporation developed and commercialized technologies for identifying, locating, and monitoring people, animals, products, and physical assets. Its best-documented business area combined radio-frequency identification with Global Positioning System and satellite communications capabilities. These technologies supported animal identification, food-supply monitoring, commercial asset tracking, government and military applications, and specialized search-and-rescue systems. The company’s animal-identification activities included implantable RFID microchips, scanners, and antennas for pets, wildlife, and livestock. Digital Angel also described applications for end-to-end food-safety systems, in which identification and tracking technologies could be used to monitor products through parts of the supply chain. Its GPS and satellite work included search-and-rescue transponders designed to track aircraft, ships, and other high-value assets for military and private-sector users. Digital Angel’s corporate history became closely linked to VeriChip, a company associated with implantable RFID technology for humans. Digital Angel formerly owned a 49 percent minority position in VeriChip. The human-implant application attracted criticism and concern from civil-liberties advocates, particularly around privacy, surveillance, consent, and the potential uses of implanted identification technology. Digital Angel divested its interest in VeriChip in 2008. VeriChip later combined with Steel Vault Corporation to form PositiveID. PositiveID subsequently sought to acquire Digital Angel. In 2010 it made a friendly acquisition attempt, but Digital Angel’s board unanimously rejected the proposal. The episode is significant because it shows the continuing corporate relationship between Digital Angel and the business that had developed from VeriChip, while also demonstrating that Digital Angel remained an independent company at that point. Digital Angel operated its animal-identification business through Destron Fearing. In July 2011, the company sold Destron Fearing to Allflex USA for $25 million. The transaction transferred a substantial part of Digital Angel’s animal-identification portfolio and represented a strategic change in the company’s business mix. The company also owned Signature Communications, a United Kingdom distributor of two-way communications equipment. Signature Communications supplied conventional radio systems for safety, security, construction, and manufacturing customers. It also distributed trunked radio systems for larger organizations, including local authorities and public utilities. This activity gave Digital Angel an operating presence in communications distribution in addition to its proprietary tracking and identification work. The supplied reference material further characterizes Digital Angel as a developer and publisher of consumer applications and mobile games for tablets, smartphones, and other mobile devices. The available source does not provide a sufficiently detailed chronology of this software activity, nor does it identify particular applications, launch dates, financial performance, or the relationship between the mobile business and the company’s earlier hardware operations. Leadership records in the available material identify Randy Geissler as chief executive from 2000 to 2003. Joseph J. Grillo became chief executive on January 2, 2008, succeeding Kevin McGrath. Daniel E. Penni served as interim chief executive beginning February 1, 2012, and L. Michael Haller was appointed chief executive on August 23, 2012. The supplied references do not establish Digital Angel’s current legal status, ownership, headquarters, or whether it continues to operate under the same name.
