MIT’s Biodegradable Capsule Confirms Medication Ingestion in Real Time

MIT engineers have developed a biodegradable ingestible capsule with a zinc-cellulose antenna and a micro-RFID chip that emits a real-time signal confirming a pill has been swallowed. The capsule dissolves in the stomach while the RFID component is excreted, enabling noninvasive adherence monitoring for critical therapies (e.g., transplant immunosuppression) and potential integration with health records. The SAFARI project uses safe, eco-friendly materials and aims for human trials, offering a pathway to real-time feedback without bulky wearables.

"Global Hotel Security Alert: 3 Million Door Locks Vulnerable to Simple Hack"

A security flaw in the RFID-based keycard locks by Dormakaba, affecting Saflok systems installed in doors across 131 countries, allows hackers to open over 3 million hotel doors worldwide with just two taps using a specialized RFID device to read and duplicate a crucial code from a hotel's keycard. The vulnerability exploits weaknesses in Dormakaba's encryption and the underlying RFID system, enabling the creation of functional keycards capable of unlocking doors. While a fix is rolling out, it may take months or years to be in place worldwide, and many Saflok lock systems remain unupdated.

"Security Flaw Exposes Millions of Hotel Door Locks to Hackers"

Researchers have disclosed a series of security flaws, dubbed "Unsaflok," that impact 3 million Saflok electronic RFID locks deployed in 13,000 hotels worldwide, allowing attackers to easily unlock any door in a hotel by forging a pair of keycards. The vulnerabilities were discovered by a team of researchers who reverse-engineered Dormakaba's front desk software and a lock programming device, enabling them to create forged keycards that could open any room on the property. While the manufacturer is actively working to mitigate the flaw, as of March 2024, 64% of the locks remain vulnerable, and guests can check their keycard type using the NFC Taginfo app to determine if their locks are vulnerable.

"Tamper-Proof ID Tag Authenticates Almost Anything"

MIT researchers have developed a tiny, tamper-proof ID tag that utilizes terahertz waves to authenticate items, offering improved security over traditional RFIDs. By mixing microscopic metal particles into the glue that sticks the tag to an object, a unique pattern is created, akin to a fingerprint, which is used for authentication. A machine-learning model has been demonstrated to detect tampering with over 99 percent accuracy. While the tag is cheap and small enough to attach to items throughout a supply chain, it is limited by the distance and angle between the sensor and tag. The researchers hope to address these limitations and inspire further exploration of terahertz applications beyond broadband wireless.

"Tech Strategies: America's Retail Giants Combat Organized Retail Theft"

Major retailers in the United States, including Walmart, Target, Lowe's, Kroger, Macy's, and CVS, are partnering with technology companies to combat organized retail theft using advanced technologies such as AI-powered video surveillance systems, facial recognition cameras, license-plate and vehicle readers, autonomous security robots, RFID tags, and predictive analytic software. The goal is to deter criminals and make theft less appealing by detecting and identifying potential offenders before they commit crimes. While these technologies show promise in reducing theft, retailers must be mindful of ethical concerns and ensure that human oversight is maintained to prevent any negative consequences for customers or employees.

Augmented Reality Gets X-Ray Vision Upgrade with Microsoft's HoloLens

MIT researchers have developed an augmented reality (AR) technology called X-AR, which uses a flexible antenna to locate specific objects outside the wearer's line of sight, as long as they're marked with a radio frequency identification tag and less than 15 feet away. The technology could be used in warehouses, shipping, retail, and other places where RFID tags are commonly used. It could also have potential applications in determining food safety and aiding search and rescue efforts.
