The Six-Lakh-Rupee Slippers That Talked Back
Inside the high-tech, wireless, and wildly expensive world of Rajasthan’s REET Bluetooth footwear racket that forced a statewide barefoot examination order.

If you walked through the bustling markets of Bikaner or Ajmer in late September 2021, you could purchase a standard pair of rubber strap slippers—the kind favored by millions across India for bathroom visits and evening walks—for roughly one hundred rupees.
Unless, of course, your slippers were equipped with a micro-SIM card reader, a rechargeable lithium battery, an induction transmitter, and an invisible Bluetooth connection to a micro-earpiece smaller than a grain of rice.
In that case, the price was **six lakh rupees**.

What Actually Happened
On Sunday, 26 September 2021, the state of Rajasthan ground to a virtual halt. Over 1.6 million candidates were registered to sit for the Rajasthan Eligibility Examination for Teachers (REET) across four thousand designated examination centres.
Given the rampant history of paper leaks and mass cheating syndicates in North India, the state administration mobilized like a military command: - Thousands of armed police personnel were deployed to checkpoints. - Mobile internet, mobile data, and SMS services were suspended across sixteen districts from 6:00 AM to 6:00 PM to prevent paper circulation on WhatsApp and Telegram. - Metal detectors and thermal scanners were installed at entrance gates.
Yet, where there is an internet blackout, there is human engineering.
An organized syndicate—led by a coaching centre operator named Tulsaram Kaler—devised a hardware workaround that bypassed the state's mobile internet blackout entirely. The solution did not require cellular data or Wi-Fi; it operated on conventional 2G voice networks.
The syndicate hollowed out the dense foam soles of standard rubber slippers. Inside the cavity, they embedded a custom printed circuit board (PCB), a GSM SIM module, a tiny lithium-polymer battery, and an induction coil. The slipper was then resealed with industrial adhesive, sanded down, and painted so that it appeared indistinguishable from ordinary market footwear.
The operation was ingeniously simple: 1. Outside the centre, a hidden accomplice with a question paper would dial the mobile number of the SIM card embedded in the candidate’s slipper. 2. The footwear was configured for auto-answer. When the call connected, the built-in transmitter relayed the incoming voice signal via magnetic induction to a microscopic flesh-toned earpiece inserted deep into the candidate's ear canal. 3. The candidate simply had to sit with their foot resting on the floor, listen to the answers being dictated into their ear, and bubble their OMR sheet.
The cost of this bespoke espionage gear? Between **₹2.5 lakh and ₹6 lakh per candidate**.

How People Found Out
The syndicate's fatal error lay not in its electrical engineering, but in physical ergonomics.
Around 8:30 AM on exam morning, outside the examination gates in the Gangashahar area of Bikaner, an observant police constable noticed a young candidate walking with an unnaturally stiff, awkward gait. The candidate was constantly adjusting his right foot, walking as though his slipper were made of solid lead.
Police officers stopped the candidate and asked him to step aside for a manual check. When an officer picked up the slipper, the discrepancy was immediately obvious: an ordinary rubber slipper weighs approximately 150 grams; this slipper weighed nearly half a kilogram.
The candidate was escorted to the nearest police station. Using a utility blade, officers carefully sliced through the rubber sole. The rubber parted to reveal a bright blue circuit board, neatly soldered wires, a SIM card slot, and a micro-battery.
Upon searching the candidate’s person, officers discovered that a tiny Bluetooth receiver had been pushed so deeply into his ear canal that standard tweezers could not grasp it. The candidate had to be escorted to an ENT specialist at a local hospital to have the magnetic bead surgically extracted.

The Internet Reacts
When news agencies and police departments published high-resolution photographs and teardown videos of the dissected slippers, the Indian internet erupted: - Netizens dubbed the mastermind the *"Chappal Don"* and coined satirical brand names like *"Adibas Bluetooth Pro"* and *"Air Chappal Max"*. - The exorbitant price tag—six lakh rupees—became a running joke on finance Twitter: > *"Forget Apple Watch. The most expensive wearable tech in India is a rubber chappal from Bikaner."* - Memes contrasted the sophistication of the footwear with the modest job being sought: candidates were paying corporate executive bribes to secure a Grade-3 primary school teaching post with a starting salary of ₹23,700 per month.

What the Authorities Said
Superintendent of Police (Bikaner) **Priti Chandra**, who supervised the operation, explained the scope of the bust: > *"We arrested five persons, including three candidates and two gang members. The gang had manufactured these slippers with high precision. The device was completely invisible from the outside. If our personnel had not noticed the unnatural walking style and the unusual weight of the footwear, the candidates would have walked right into the hall."*
As alerts flashed across the state police network, district collectors across Rajasthan issued an emergency directive to all four thousand exam centres: **all candidates must remove all footwear outside the gates**.
For the rest of the day, over 1.6 million candidates sat for the REET examination completely barefoot, their shoes and sandals piled in mountain-sized heaps outside school compounds.

What Happened Next
The Bikaner police bust dismantled the syndicate, arresting kingpin Tulsaram Kaler and his technical associates. Police recovered dozens of unsold Bluetooth slippers from hotel rooms in Bikaner and Ajmer.
The scandal had far-reaching legislative and procedural consequences: 1. **The Barefoot Protocol**: Across several northern Indian states, wearing closed shoes, thick-soled footwear, or boots was permanently banned at competitive entrance exams. Standard admit card guidelines now explicitly state: *"Candidates must wear only thin-soled open sandals or slippers without metallic embellishments."* 2. **The Anti-Cheating Act**: The sheer scale of the REET scandals prompted the Rajasthan Legislative Assembly to pass the *Rajasthan Public Examination (Measures for Prevention of Unfair Means) Act, 2022*, introducing prison sentences of up to ten years and fines of up to ₹10 crore for organized cheating syndicates.
