Thank you, Ricardo. Hello, everyone. In this section we will be breaking down our business unit's performance through the first quarter of 2024. Starting with payments on Slide 8. We showed that our merchant acquiring business keeps growing through the combination of our superior value proposition and the broad bridge of our sales channel, positively impacted by our sales force expansion that has started in the last year.
We have been able to accelerate TPV growth faster than the industry, driven by our main merchant segments. TPV reached BRL 112 billion in Q1 '24, growing 27% year-over-year with TPV per merchant growing 37% on a yearly basis. Continuing our strategy to expand our payments business focus on merchants profile with better engagement and profitability, we observed 5% growth year-over-year of our active merchants on a third-day criteria when excluding Nano-merchants.
Moving on to Slide 9. Let's look further into MSMB segment, which gathers micro merchants with monthly TPV up to BRL 15,000 and small and medium merchants business with monthly TPV from BRL 15,000 up to BRL 1 million. MSMB's TPV grew 24% year-over-year, reaching BRL 77.6 billion in the first quarter of 2024. The strong merchant's gross adds positively contributed to this performance, combined with higher productivity in our hubs and geographic expansion.
We present an unparalleled value proposition to MSMB in Brazil. Our comprehensive approach embraces a broad reach of sales channel, ensuring maximum exposure and accessibility for merchants. With instant settlement, we offer the cheapest working capital source empowering business to drive without financial strain.
Fast POS delivery and replacement ensures an interrupted service while our seamless integration of payments and banking simplifies transactions, enhancing efficiency and engagement. Additionally, we are also happy to share that PagVendas, our ERP software has surpassed 1 million users showing how we remain committed to innovation and customer satisfaction.
Moving on to the next slide here on Slide 10, we show how our TPV from the LMEC segment has performed comprised by large merchants, e-commerce and cross-border clients. In the first quarter of 2024, this segment posted a 35% TPV growth in comparison to Q1 '23, reaching BRL 34.2 billion in transactions. We are increasing our share of wallet on large merchant segment that gathers business with monthly TPV above BRL 1 million driven by the development of an integrated ominchannel payments platform embedded with management software solutions for more than 350 software partners from the new PagBank partnership program.
Our online segment posted a strong TPV growth with e-commerce boosted by our strategy to unraveling PIX scale code and tap on phone for e-commerce platforms. Leveraging facial authentication helped to enhance security measures in online transactions, ensuring trust and reliability. Furthermore, our cross-border unit under the brand PagSeguro International, is connecting foreign merchants with Latin American buyers fostering a seamless experience and enriched global commerce ecosystem.
Moving on to the banking business. Our strategy to provide seamless experience combining payments, value-added service and banking through multiple interfaces for merchants and consumers continued to drive engagement up. This engagement increase resulted in over BRL 66 billion in PagBank cash-in composed by fixed P2P, wire transfers, deposits through Boleto and invoices into PagBank accounts from other financial institutions.
Finally, cash-in per active client, an important indicator of our client engagement grew 44% year-over-year, reaching BRL 3900 per client. Our active bank client base reached 16.9 million clients, a 4% year-over-year growth. We also present in this slide, the breakdown of active customers growth by product which demonstrate the increasing penetration of our financial products and service and how powerful the value proposition of our banking platform is. The number of clients using investments and credit products clear stands out, growing 85% and 235%, respectively, compared to Q1 '23.
On Slide 12, we shared that deposits were up 64% compared to the first quarter of 2024, reaching a record of almost BRL 31 billion, boosted by our AAA rating attributed by S&P Global which enhanced our CDs distribution among retail and institutional investors an on and off platform. Checking account balance, the cheapest funding source and a key performance indicator to measure client engagement grew 37% year-over-year. Annual percentage yield for checking accounts and total deposits remained compelling, creating a unique engine connecting pricing power without harming profitability by lowering the average cost of funding for the company.
We remain so excited about the Brazilian payments opportunity and have a privileged position of holding a solid balance sheet and low cost of funding like big banks, while demonstrating speed and superior product user experience like FinTechs.
Moving on to the next slide. Slide 13 shows that our credit portfolio resumed growth since Q3 2023 and this quarter, it reached BRL 2.7 billion, with increasing share of secured products now representing more than 70% of our book loan promoting financial inclusion, education and important financing lines to our clients through this product. We successfully passed through the pandemic, the rising of Brazilian interest rates and one of the worst credit cycles in the country with no negative impacts in our financial results and without compromising our long-term growth strategy.
During this period, we took the opportunity to completely review our credit cycle fundamentals, enhancing our onboarding process, fraud prevention, risk assessment, underwriting and collection policies and procedures. The results were fully captured by the relevant improvement in our asset quality, lowering our NPL90 from 18% to 4.5% in 12 months. And now we see an opportunity to gradually resume the credit underwriting of other credit lines in the second half of 2024 such as working capital loans and overdraft account limits.
Now I turn over to Artur for the financial highlights of the first quarter of 2024. Arthur, please.
