How a Bern P300 EEG Test Actually Runs
The practical detail clients ask about most: how do we get to Bern, where does the test happen, what does the day look like, what does the written report include. Everything below is the same whether you book a single test, a two-person visit, or a dedicated visit.
Travel to Bern
UK-qualified examiner inbound to Zurich Airport (ZRH) — a short flight of under two hours from the UK. Medical-grade 8-channel BrainBit EEG kit travels as cabin baggage in cushioned cases. Examiner arrives 2-3 hours before test start to allow for any travel delay.
Venue in Bern
a discreet suite in a Bern or nearby hotel, around 1 hour 20 minutes from Zurich. Corporate premises also accepted for workplace investigations. Venue is booked in advance and confirmed in writing once payment clears — strict confidentiality from the front desk.
The Bern Day
30-minute pre-test interview, 30 mins P300 EEG examination, 30-minute post-test debrief, 30-minute waveform analysis. Total venue time: 3.5 hours. Written report handed to the paying client before they leave the venue.
The Report
8-page forensic report — raw waveform data, P300 spike analysis per probe question, deception score breakdown, methodology summary, signed certificate of examination. Issued only to the paying client; never copied or shared.
Confidentiality
The Bern venue is booked under our company name, not yours. The examiner arrives in plain clothes with unmarked equipment cases. Nobody at the venue is told what the booking is for. Records are held under UK GDPR equivalent standards.
Payment from Bern
EUR or GBP via international bank transfer, SEPA, Wise, or major credit card. Invoiced by DadLink Technologies Limited (UK). Full payment confirms the booking — this is how we hold your travel slot. No deposits on international bookings.
Brain-Wave Testing. Not Sweat & Heart Rate.
Why does P300 EEG matter for your Bern case specifically? Because the people most likely to fail a polygraph are anxious truth-tellers and the people most likely to pass it are calm, prepared liars. P300 EEG flips that on its head: it measures brain recognition, which does not care how nervous you are. The honest person passes, the guilty one fails.
Traditional Polygraph
- Measures anxiety symptoms — not truth directly
- Heavily affected by nerves, anger, stress
- Countermeasures documented widely online
- Accuracy ~85-89% on single-issue tests
- Subjective chart interpretation
- Limited availability in Bern
P300 EEG (What We Do)
- Measures brain recognition — not emotional state
- Involuntary neural response — hard to suppress
- Countermeasures don't block P300 spikes
- 95% accuracy on guilty-knowledge protocols
- Objective waveform analysis
- UK-qualified examiner flown to Bern
Built for Bern's Most Common Cases
From Bern couples to Bern family solicitors to Bern SMEs, the cases that come through our doors have more in common than you would think. Six clean categories cover most of it — and you can probably see your situation in one of them already.
Relationship & Infidelity
Private, discreet testing for cheating allegations, emotional affairs, messaging history disputes, or to verify a partner's statements before trust is rebuilt. Confidential venue, written report within 1 hour. Test both partners on the same visit for just £799.
Family & Household
Theft in the home, inheritance disputes, adult children under suspicion, sibling disagreements, or accusations within blended families. Clear, objective answers without police involvement.
Business & Workplace
Specific-incident investigations with employee consent — missing stock, data leaks, suspected fraud, internal misconduct allegations. Test multiple suspects on one visit for significantly lower per-test cost.
False Accusations
If you've been accused of theft, dishonesty or misconduct at work or in your personal life, a passed P300 EEG test provides objective brain-wave evidence that you're telling the truth — far more robust than your word alone.
Pre-Relationship / New Partner
Past behaviour verification, dating-profile honesty, discrete checks before a serious commitment. Used quietly by many Bern clients before getting engaged, buying property together, or introducing someone to children.
Second Opinion
Previously failed a polygraph elsewhere and want an independent P300 EEG test on the same facts? P300 measures brain recognition, not anxiety — so a nervous polygraph result doesn't predict a P300 result. Clean slate, different technology.
What Bern Clients Say
★ 4.9 / 5 · based on 499 verified reviews across Deception Detection UK
Three-person business partner test came in cheaper than one polygraph each
"We needed all three founders tested independently after a money dispute. The grouped-visit pricing meant the whole exercise came in cheaper than three separate polygraphs would have been. Reports in our hands same day."
Cleared a teenage son of a drug accusation in the home
"We had wrongly accused our teenage son of something and needed to make it right with proof he could see and accept. The test cleared him cleanly. The conversation we had afterwards rebuilt trust in a way an apology alone could not."
Best technology I have seen in this space
"I work in tech and was sceptical until I saw the actual waveform data. The 8-channel EEG plus the methodology behind the analysis is genuinely impressive. Different league to anything else marketed as a lie detector."
Two-test couple visit handled with sensitivity
"Booked a two-test couple visit after months of arguments. The examiner separated us professionally, ran identical protocols on each, and gave us the results privately first before any joint conversation. Handled with care."
Definitive report stood up to scrutiny
"Used the report in a formal grievance hearing and the other side could not credibly challenge it. The waveform analysis and methodology section were strong enough that we did not need any expert witness in addition."

Common Questions From Bern Clients
We run a rolling schedule of Switzerland visits and plan each trip around confirmed bookings. For a Bern booking you can either join the next scheduled visit — cheaper, you take the next available slot — or book a dedicated visit at £1,499 where the examiner flies out for your Bern case alone within 14 days. Either way the examiner arrives into Zurich Airport (ZRH) by a short flight of under two hours from the UK and can usually complete everything in a single day.
Yes — and it's our most popular option in Bern. Each additional person on the same visit is only £299, because our flights and venue costs are already covered. Two tests on the same day costs £799 instead of £1,398 if booked separately. Three tests for £1,297. Five or more — get in touch for a group rate. Ideal for couples, business partners, family members in a dispute, or staff in a specific-incident investigation.
Traditional polygraph measures anxiety — breathing, heart rate, sweat. P300 EEG measures a specific brain-wave that fires involuntarily when your brain recognises a detail you've seen or done before. It's measurably more accurate (95% vs ~85%), not defeated by common countermeasures, and not distorted by nervousness. Crucially, a guilty person's brain still recognises the crime even if they're calm — and an innocent person's brain won't recognise details they've never seen, no matter how anxious they are.
Strictly confidential. Tests take place in private booked venues. Reports are issued only to the paying client. We operate under UK GDPR standards, consistent with Switzerland's Federal Act on Data Protection (FADP) and do not share, store or disclose any case information to third parties without written instruction. Nothing is filed with any authority, employer or family member unless you explicitly ask us to.
Very common reason for booking us. Traditional polygraph results can be distorted by nerves, medication, medical conditions, or poor question design — a genuinely truthful person can fail simply by being anxious. P300 EEG measures something different: brain recognition, not anxiety. A P300 test on the same underlying facts can provide a clear, independent second result.
We accept GBP or CHF payment via international bank transfer, Wise, or major credit and debit cards. All invoices are issued by DadLink Technologies Limited (UK). Full payment is required to confirm the booking — we don't take deposits on international bookings. This protects both parties and secures examiner travel arrangements.
Tests are conducted in English. If the subject needs a German, French, Italian or other interpreter, we can arrange one locally — just raise this at the enquiry stage so we can factor it into scheduling.
Yes. We travel widely across Europe. If you're in France, Germany, Italy, Austria or elsewhere near Switzerland, get in touch and we'll quote your location on the same flown-in basis — the pricing structure is identical, adjusted only for the specific travel route. Book or enquire here.
