She became the England women's wicket-keeper in 1992, regained her place in the team in 2003 following a year’s absence and is the most successful keeper in the women’s game.
She was part of the England squad that won the Women's World Cup in 1993 and also featured in the 1997 and 2000 tournaments before being selected in the squad for the 2005 World Cup in South Africa.
Smit performed well behind the stumps in South Africa, especially against Sri Lanka when she claimed two catches and two stumpings, and helped England reach the semi-finals before they lost to tournament favourites Australia.
She played three of the five one-day internationals against Australia the following summer in the NatWest Women's Series and was part of the team that won at Stratford to clinch England's first win against their rivals in 12 years.
She also played both npower Tests as England won the series 1-0 to claim the Ashes.
Smit was then selected for the 2005 winter tour and helped England beat Sri Lanka 2-0 before drawing a one-off Test in India, although the hosts took the ODI series 4-1.
Her best performance with the bat came in the Test in Delhi when, replying to India's first-innings total of 289, England were in trouble at 104 for eight and with Katherine Brunt unable to bat.
Smit (21 not out) shared a 50-run stand for the last wicket with Beth Morgan, however, which saw England avoid the follow-on and ultimately draw the Test.
She holds a share of the ODI record for England’s fourth- and fifth-wicket partnerships, putting on an unbeaten 131 with Charlotte Edwards against India in Pune in 1997 and an unbeaten 188 with Claire Taylor against New Zealand in Lincoln in 2003.
Her last Test came in 2006 against India, after which she was replaced behind the stumps by young Sussex wicketkeeper Sarah Taylor.
Despite playing in a handful of ODIs in 2006 and 2007, she was selected for the tour of Australia and New Zealand in 2008 as England look to retain the Ashes.
She played in a solitary competitive game - the Twenty20 international - on the Australia leg of the tour, and announced her retirement from international cricket after the one-day series was drawn.
